What would happen if germinating seeds are replaced by boiled seeds? Answer: As germinating seeds respire actively and at a faster rate, they are taken for the experiment. Boiled seeds do not respire and so no results will be obtained if they replace the germinating seeds in the experiment.
What will happen if boiled seeds are placed in the flask instead of germinating seeds in the experiment to prove that respiration occurs in plants justify?
7. No, they cannot be used as boiled seeds cannot undergo respiration. The experiment will show no result.
Can seeds germinate after being boiled?
Additionally, boiling seeds also destroy the enzymes required for germination. This destroys cells, causing death. Following this, cells do not grow and divide. Hence, boiled seeds fail to germinate.
What happens to a seed when it is boiled?
The boiled seeds failed to sprout because boiling denatures or damages certain enzymes or proteins that are required for germination. Thus, boiling kills the seeds. Seeds need moisture (water) and air for sprouting. When the seeds are boiled moisture content will lost and enzymes or proteins are killed.
Why seeds are boiled in control experiment?
In experiments on respiration, the seeds taken as control are boiled to stop respiration in the seeds.
Why boiled seeds do not respire?
Answer. Hi there! Boiled seeds won’t grow – evidence that they have been killed by the boiling process. The high temperature irreversibly destroys crucial proteins in the plant cells, including structural proteins, so the cells fall apart (that’s why the water goes green when you boil them) and cease respiration.
Why are the boiled seeds treated with carbolic acid for experiments on respiration?
Add some carbolic acid to flask B to prevent the growth of bacteria on dead seeds.
How does boiled water affect germination?
While you can tumble or scrape seeds with sandpaper or a file to help water penetrate their hard exteriors, hot water may also work for some seeds. The water should be close to boiling, but you should not boil the seeds. Boiling seeds will kill the embryos inside and the seeds will not germinate.
Can we boil seeds?
Boiling the seeds softens the fiber and releases it into the liquid, which when left to stand, gels. Flax seeds are boiled to produce flax gel. The boiled seeds may be eaten, used in baked goods or in cereal, or tossed away.
How does hot water affect seed germination?
Hot water seed treatment has the beneficial effect of priming seeds, resulting in faster germination than untreated seed. However, the treatment can decrease germination rates, especially of older seed (more than 1 year old) or seeds that were grown under stressful environmental conditions.
How boiled seeds are different from sprouted seeds?
Boiling the seeds destroys the cell organelles which are required for germination. Therefore, they fail to grow. Hence, boiling kills all the living properties of seeds, so only living seed can be germinated and converted to sprouts.
Can boiled seeds still produce heat?
The temperature of the boiled seeds remains unchanged. The temperature of the unboiled seeds increases gradually and levels off as the seeds begin germinating.
Do roasted seeds sprout faster?
Answer. Answer: No, once you roast the seed it will not be able to sprout. Seeds are technically alive but dormant until they are given the proper conditions to grow.
What is the significance of Sterilising the seeds before they are used?
Seed sanitizing treatments can be used to prevent seed-borne plant diseases, especially those caused by bacteria, and can minimize the potential risks associated with seed contaminated with foodborne pathogens. Improper use of seed treatments can damage or kill the seeds.
Why did we use germinating seeds in this experiment?
Germinating seeds are used in the experiment of the release of carbon dioxide during respiration because they respire a lot more than a plant that has already grown. A new plant will require more energy and oxygen to get started.
What is the relationship of aerobic respiration and seed germination explain your answer?
As cellular respiration takes place in the germinating seeds, the carbon dioxide given off is in direct proportion to the oxygen being taken up by the seed. However, this carbon dioxide (gas) reacts with CaO to form calcium carbonate (solid), which reduces the amount of gas in the tube and allows the water to rise.
Why should germinating seeds be kept moist during respiration experiment?
Why should the seeds be kept moist during the experiment? Answer: Germinating seeds require water for growth. If moisture is not available, the seeds dry up, and rate of respiration would fall.
Why do germinating seeds respire more?
Seeds do not possess the required photosynthetic abilities/resources to synthesize their own energy. Hence, there is a high rate of consumption of oxygen in seeds that are germinating as they are living and need extra oxygen to grow.
What happens during seed germination heat is liberated?
The germinating seeds can respire by using the water. When there is an increase in the respiration process, the breakdown of the glucose molecule occurs which results in the evolution of energy in the form of heat.
Does germinating seeds produce carbon dioxide?
The germinating seeds in the conical flask release CO2 during respiration, which is absorbed by the KOH solution kept in the small test tube. This creates a partial vacuum in the flask that forces the water up the delivery tube. Thus, it proves that germinating seeds produce carbon dioxide during respiration.
Why is boiled and cooled glucose covered with paraffin?
(B) To prevent supply of air, boiled and cooled glucose is covered with paraffin.
Do germinating seeds respire aerobically?
Oxygen is required by the germinating seed during aerobic respiration, it is the main source of energy for the seedlings until the formation of leaves. Oxygen is an atmospheric gas that is found in soil pore spaces.
Are boiled seeds performing cellular respiration?
As cellular respiration occurs, more oxygen is consumed, with more oxygen being consumed (high rate of aerobic respiration) by the unboiled germinating seeds compared to the boiled seeds which virtually respired (lower rate of oxygen consumption compared to unboiled peas).
What is boiling water treatment for seeds?
Hot-water seed treatment is one method that you can use to eradicate, or at least reduce the level of pathogens (particularly bacterial pathogens), in vegetable seed. Some commercial vegetable seed companies routinely use this method (as well as other more stringent decontamination methods) to eradicate pathogens.
What happens during seed germination?
In the process of seed germination, water is absorbed by the embryo, which results in the rehydration and expansion of the cells. Shortly after the beginning of water uptake, or imbibition, the rate of respiration increases, and various metabolic processes, suspended or much reduced during dormancy, resume.
Why do dry seeds not germinate?
Solution : Dry seeds are known as dormant seeds. They remain alive without germinating for months or years. When the seed is soaked in water, enzymes get activated by absorbing water, and thus, it helps in germination and development of embryo.
Can we boil flaxseed?
Also, you can boil flax seeds and consume. You can take 200 ml of water and add 1 spoon of flax seeds to it. Once, the water becomes half, you can sieve it and have. The boiled water will be a bit sticky but its very effective.
Will seeds germinate in cold weather?
For many garden plants in fact, a soil temperature below 50°F can be a problem. With temperatures in the 40s, seeds will readily absorb water, but not start to grow. This creates an opportunity for disease and rot, which can result in damping-off or poor growth.
Can I soak seeds in hot water?
Some seeds can tolerate boiling water, but as the tolerance for heat can vary greatly from species to species, hot tap water is safest for seed soaking. Once your bowl is filled with hot water, place your seeds inside the bowl, then allow the seeds to stay in the water as it cools down.
How do you speed up seed germination?
One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don’t soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.
Does salt water affect seed germination?
In general, high soil salinity inhibits seed germination due to the low osmotic potential created around the seed, which prevents water uptake (Welbaum et al., 1990). In addition, high concentrations of sodium and chloride ions in the soil may be toxic to seeds (Khajeh-Hosseini et al., 2003).
Are sprouts better than boiled seeds?
As per experts, raw sprouts are even difficult to digest as compared to the cooked ones. Your body might not be able to absorb all the nutrients of the seeds and beans in the raw form. Cooking the sprouts slightly makes the nutrient more accessible to the body.
Are boiled seeds healthy?
They are good sources of iron and copper which are essential to maintain the red blood cell count. They strengthen the immune system by providing the essential vitamin A and vitamin C. They are a rich source of omega-3 fatty acids which is important for a healthy heart.
What are sprouted seed?
Sprouting is the natural process by which seeds or spores germinate and put out shoots, and already established plants produce new leaves or buds, or other structures experience further growth.
What do seeds need to germinate?
All seeds need water, oxygen and the right temperature to germinate. Dormancy is a state of suspended animation in which seeds delay germination until conditions are right for survival and growth. Some Australian plants need fire or smoke to germinate, while others rely on insects and animals.
Do seeds need light to germinate?
Most seeds germinate best under dark conditions and might even be inhibited by light (e.g., Phacelia and Allium spp.). However, some species (e.g., Begonia, Primula, Coleus) need light to germinate (Miles and Brown 2007). Don’t confuse seed light requirements with what seedlings need. All seedlings require sunlight.
Can we use deep fried seeds instead of sprouted seeds Why?
And after the seeds die out it is not possible for the seeds to germinate and sprout. So as a result it’s not possible for the seeds to germinate after it has been fried in the oil. Hence the seed will not germinate.
Do sprouts grow better in dark or light?
LIGHT OR DARKNESS
It does not matter if your kitchen is very bright or shady when you grow sprouts. In nature, the seeds germinate in the dark soil or in the more light-filled topsoil. Regardless of the depth in the soil, the root will grow downwards and the stem will grow upwards.
Can you sprout any seeds?
You can sprout almost any legume, seed, or nut. Everything from chickpeas to broccoli to millet to radish to red clover to mung beans.
How does temperature affect the rate of respiration in germinating seeds?
Additionally, that at higher temperatures, the rate of cellular respiration in the seeds will increase.
Why were germinating seeds used instead of dormant seeds?
Seed dormancy is the state in which seed is unable to germinate, even under ideal growing conditions (Merriam-Webster). Because dormancy can be broken by most ideal growing conditions (different and specific for each species), the seeds germinate when they are the most likely to flourish.
What is the effect of germination on the rate of cellular respiration in peas?
The affect of germination on the rate of cell respiration in peas is that in peas that are germinated, the rate of cell respiration is higher because the cells are growing/going through mitosis which requires energy/ATP in order to be carried out which is generated through the process of cellular respiration.
What will happen if boiled seeds are placed in the flask instead of germinating seeds in the experiment to prove that respiration occurs in plants justify?
7. No, they cannot be used as boiled seeds cannot undergo respiration. The experiment will show no result.
What factors affect seed germination experiment?
Several variables might affect the germination, these variables include light, temperature, water, soil type, and air quality. Choose one variable to investigate.
What type of respiration takes place in germinating seeds?
Anaerobic respiration is an incomplete oxidation process. during germination seed respire in the absence of oxygen.
How does a germinating seed obtain oxygen?
The seed continues to breathe until the plant can make its own food via the process of photosynthesis. The oxygen comes from tiny pockets of air in the soil. Most loose soil has plenty of air for seeds, but if the seed is surrounded by water, it will not be able to obtain enough oxygen to germinate.
Why do non germinated seeds not respire?
In addition to the germinating peas, the non-germinating peas, are not germinating so because of this they do not need significant amount of ATP production. Therefore, the non-germinating peas have a significantly low rate of respiration in comparison with the germinating peas.
What happens if instead of moist seeds boiled seeds are used for the experiment?
What would happen if germinating seeds are replaced by boiled seeds? Answer: As germinating seeds respire actively and at a faster rate, they are taken for the experiment. Boiled seeds do not respire and so no results will be obtained if they replace the germinating seeds in the experiment.
What kind of experiment can you do to prove that seeds need water to germinate?
Three bean seed experiment
Place the slide in the beaker containing water in such a way that the seed at top is above the water, the middle seed is at the water level and the third seed is submerged in water. Observation: The top seed does not germinate as it gets oxygen but no water.
What could be the possible reasons for rise in temperature in flask containing germinating seeds?
Expert Answer:
- The aim of the experiment is to show that heat is evolved during respiration.
- After few hours, the thermometer in flask A shows a higher reading, thus indicating a rise in temperature due to heat evolved by the germinating seeds.
Does germination have an effect on respiration Why or why not?
Germination is the growth processes of a seed. It requires a lot of energy to break the seed coat and as it continues to grow this energy need increases. Respiration is required to access this energy so as the seed germinates its respiration rates increase.
Why the germinating seeds have a higher rate of respiration compared to non-germinating seeds?
The germinating seeds will have a higher rate of oxygen consumption than the non-germinating seeds because the germinating seeds are living and need extra oxygen so that they can grow, whereas the non-germinating seeds are not nearly as active and won’t respire as much.
Do germinating seeds release heat?
Energy is released during the germination process. Seeds respire and release energy during the germination process. Heat is produced during the respiration process.
How can you prove that heat is liberated during respiration using germinating seeds?
Hint: A thermo flask along with a thermometer is used to prove that heat is liberated during respiration. As the germinating gram seeds in the thermo flask respire, the temperature in the thermometer rises indicating release of heat energy.
What happens to the given out by germinating seeds while performing the experiment?
Actually, the germinating seeds respire and produce CO2, which is absorbed by KOH solution. This creates a vacuum in the conical flask. The air present in the bent glass tube moves into the conical flask.
How does carbon dioxide affect seed germination?
Like seed mass, reported seed germination responses to elevated CO2 have been variable. The reported changes in seed C/N ratio can decrease seed protein content which may eventually lead to reduced viability. Conversely, increased ethylene production may stimulate germination in some species.
What happens when glucose is boiled?
Answer: Boil the glucose solution to sterelise it and remove any oxygen, leaving behind the glucose needed for anaerobic respiration. Yeast will respire anaerobically producing, alcohol, heat and co2 that can be collected in lime water.
Why does glucose need to boiled?
Boil the glucose solution to sterilise it and remove any oxygen, leaving behind the glucose needed for anaerobic respiration.
What is anaerobic germination?
Anaerobic germination (AG) is an important trait for direct-seeded rice (DSR) to be successful. Rice usually has low germination under anaerobic conditions, which leads to a poor crop stand in DSR when rain occurs after seeding. The ability of rice to germinate under water reduces the risk of poor crop stand.
