What gas is needed by the seed during germination?
Oxygen gas is needed by the seed during germination. Aerobic respiration takes place during seed germination to release lots of energy required for this process.
Explain how a seed obtains its food store from its parent plant.?
A seed obtains its food store from its parent plant through a process called seed maturation. During seed development, the parent plant transfers nutrients and energy to the seed through the vascular tissues. These nutrients, such as carbohydrates, proteins, and fats, are stored within the seed to support germination and early growth when the seed begins to sprout.
What gas is released during germination process?
During the germination process, oxygen is absorbed by the seed and carbon dioxide is released as a byproduct of respiration. This gas exchange is necessary for energy production and growth in the germinating seed.
What is epigeal and hypogeal germination?
Epigeal germination is when the cotyledons emerge above the soil surface during seed germination. Hypogeal germination is when the cotyledons remain below the soil surface during seed germination.
How does oxygen gets into the seed during germination?
During germination, the seed absorbs oxygen through small openings called micropyles. These openings allow oxygen to enter the seed and reach the embryo, which needs oxygen for respiration to break down stored nutrients and provide energy for growth.
When does the seed turn green?
during germination
State the difference in how seeds react for both types of germination?
Epigeal germination is the process in which the seed leaves or the cotyledons are brought on to the surface along with the shoot during germination. Hypogeal germination is the process in which the seed leaves or the cotyledons remain below the soil surface during germination.
Once respiration starts in a seed germination has begun?
Yes, once respiration starts in a seed, it signifies that germination has begun. During this phase, the seed absorbs water, activating metabolic processes and leading to the breakdown of stored nutrients for energy. This energy supports the growth of the embryo, eventually leading to the emergence of the seedling. Proper environmental conditions, such as moisture, temperature, and oxygen, are crucial for successful germination.
How does the embryo get food for germination?
The embryo in a seed gets its food from the endosperm or cotyledons within the seed. During germination, enzymes break down the stored food reserves in the seed to provide energy for the embryo to grow and develop into a seedling.
Where does a seed get its food from after it germinates?
A seed derives its food from the cotyledones or endosperm during germination
Why does the mass of a seed decrease during germination?
During germination, a seed utilizes its stored nutrients, primarily carbohydrates and proteins, to support the growth of the emerging plant. As these reserves are metabolized for energy and growth, the overall mass of the seed decreases. Additionally, water absorption can lead to weight changes, but the net effect is often a reduction in mass as the seed transitions to a growing seedling.
Germination happens between which two stages?
Germination is when a plant grows from a seed. It occurs between the dormancy stage of a seed and the establishment stage of the seed.
