you asked: why boiled seeds do not respire?
In the realm of life, seeds possess an inherent ability to respire, a fundamental process that enables them to extract energy from their stored reserves. However, when subjected to the intense heat of boiling water, this vital function ceases to exist. The high temperatures denature the enzymes responsible for respiration, rendering them incapable of performing their intricate tasks. Consequently, the seeds lose their ability to break down complex molecules into simpler forms, effectively halting the production of energy. Without this essential process, the seeds are unable to germinate, depriving them of the opportunity to embark on the journey of growth and development.
why boiled seeds are dead?
When seeds are boiled, they are exposed to high temperatures that cause the proteins and other molecules within the seed to denature and break down. This process kills the embryo, which is the part of the seed that would otherwise grow into a new plant. Additionally, the high temperatures can also damage the seed coat, making it more difficult for water and nutrients to reach the embryo. Boiled seeds are therefore considered to be dead and will not germinate or grow.
why do boiled seeds not sprout class 12?
Seeds are living organisms that contain a tiny plant embryo, a food supply, and a protective coat. When conditions are favorable, the embryo germinates, and the seed sprouts. However, if seeds are boiled, they will not sprout because the high temperature kills the embryo and damages the food supply.
Boiling seeds also destroys the protective coat, making them more susceptible to attack by microorganisms. Additionally, the high temperature can cause the seed coat to become hard and impermeable, preventing water and oxygen from reaching the embryo. As a result, the seed will not be able to germinate and sprout.
do seeds need to respire?
Seeds do need to respire. They take in oxygen and release carbon dioxide, just like animals and plants. Respiration is the process by which cells break down food to produce energy. Seeds use this energy to germinate and grow.
The rate of respiration in seeds varies depending on the temperature and moisture content of the environment. Seeds respire more quickly in warm, moist conditions than they do in cold, dry conditions. This is because enzymes, which are proteins that catalyze chemical reactions in cells, work best at warm temperatures.
Seeds can respire even when they are not germinating. This is called dormant respiration. Dormant respiration is essential for keeping the seed alive and viable. It allows the seed to maintain its cellular structures and repair any damage that may occur.
When a seed germinates, the rate of respiration increases dramatically. This is because the seed is now using energy to grow and develop. The germinating seed needs to produce new cells, synthesize proteins, and transport nutrients from the seed coat to the growing seedling.
The respiration rate of a seed will continue to increase until the seedling has emerged from the seed coat and is able to photosynthesize. Once the seedling is able to photosynthesize, it will no longer need to respire to obtain energy.
what happens when you boil seeds?
Boiling seeds can have various effects depending on the type of seed and the purpose of boiling. In general, boiling seeds can soften the seed coat, making it easier for the seed to germinate. It can also kill pathogens that may be present on the seed surface, reducing the risk of disease transmission. Boiling can also help break down certain compounds in the seed, making them more digestible and easier for the plant to use during germination and growth. Additionally, boiling can help remove inhibitors that may be present in the seed, which can prevent germination. However, it’s important to note that boiling seeds for too long or at too high a temperature can damage the seed and prevent germination. Therefore, it’s crucial to follow specific guidelines and recommendations for boiling seeds based on the type of seed and the desired outcome.
can boiled gram seeds germinate?
No, boiled gram seeds cannot germinate. The process of boiling destroys the embryo of the seed, which is essential for germination. The embryo is the part of the seed that contains the genetic material and the energy reserves necessary for the growth of the new plant. Without the embryo, the seed cannot germinate and grow into a new plant.

what are germinated seeds called?
Germinated seeds are the seeds that have begun to grow. They are also known as sprouts. When a seed germinates, it absorbs water and nutrients from the soil. The seed coat breaks open, and a radicle emerges. The radicle is the first root of the plant. It grows down into the soil, anchoring the plant and absorbing water and nutrients. The hypocotyl is the stem of the plant. It grows up from the radicle and supports the cotyledons. The cotyledons are the first leaves of the plant. They are usually simple and have a different shape than the true leaves of the plant. Once the cotyledons have emerged, the plant is said to be established.
what does a seed have inside it?
A seed is a small, hard-coated structure that contains the embryo of a plant. Inside the seed, the embryo is protected by a layer of food called the endosperm. The endosperm provides the embryo with the nutrients it needs to grow. The embryo consists of a radicle, a plumule, and one or two cotyledons. The radicle is the first part of the embryo to emerge from the seed. It grows down into the soil and becomes the root of the plant. The plumule is the part of the embryo that grows up into the air. It becomes the stem and leaves of the plant. The cotyledons are the first leaves of the plant. They provide the plant with its first source of food. Seeds are dispersed by a variety of methods, including wind, water, and animals. When a seed lands in a favorable environment, it germinates and begins to grow. The embryo uses the nutrients in the endosperm to grow into a new plant.
are ungerminated seeds dead?
No, ungerminated seeds are not dead. They are alive but in a state of dormancy, waiting for the right conditions to germinate and begin growing. This dormancy can be broken by a variety of factors, such as moisture, temperature, and light. Once the seed germinates, it will begin to grow into a new plant.
do germinating seeds take in oxygen?
Germinating seeds do take in oxygen because they respire. Oxygen is necessary for the breakdown of stored food reserves within the seed, providing energy for the developing seedling. The oxygen is taken in through tiny pores on the surface of the seed coat. In exchange, carbon dioxide is released as a waste product of respiration. The amount of oxygen taken in varies depending on the type of seed, the temperature, and the availability of water. For example, corn seeds take in more oxygen than bean seeds, and seeds germinating in warm temperatures take in more oxygen than seeds germinating in cool temperatures. If oxygen is not available, the seed will not be able to germinate.
are non-germinating seeds dead?
A non-germinating seed can be either dormant or dead. A dormant seed is alive but is temporarily unable to germinate. This can be due to a variety of factors, such as a hard seed coat, a lack of water or oxygen, or the presence of a chemical inhibitor. A dead seed, on the other hand, is no longer alive and cannot germinate at all.
There are a few ways to tell if a seed is dormant or dead:
If you are unsure whether a seed is dormant or dead, you can try to germinate it. If the seed germinates, it was dormant. If the seed does not germinate, it is dead.
do seeds need sunlight to germinate?
While some seeds require sunlight to break their dormancy and start the germination process, others do not. Seeds that need light to germinate are known as photoblastic seeds, while those that do not require light are called non-photoblastic seeds. Photoblastic seeds typically have a transparent or translucent seed coat that allows light to penetrate and reach the embryo inside. Once the embryo receives enough light, it triggers a series of chemical reactions that lead to the seed germinating. Non-photoblastic seeds, on the other hand, have an opaque seed coat that blocks out light. These seeds typically germinate when they are exposed to moisture and warmth. So, while some seeds need sunlight to germinate, others do not. It all depends on the species of the seed.
why do germinated seeds respire more?
Germinated seeds respire more because they are actively growing and dividing, and this process requires energy. The energy is obtained through the breakdown of stored food reserves, such as starch and lipids, in the seed. The breakdown of these reserves releases carbon dioxide and water, which are waste products of respiration. The rate of respiration increases as the seed germinates and the new plant grows. This is because the new plant requires more energy to grow and develop. The rate of respiration also increases as the temperature rises. This is because the enzymes that catalyze the reactions of respiration work more efficiently at higher temperatures.
