In epigeal germination, the sprouting seed leaves rise above ground level, while in hypogeal germination, seed leaves emerge from the seed and remain underground or at ground level. The seed leaves that emerge from the seed coat during germination are called cotyledons. Seed germination is the growth of a seed when exposed to adequate soil conditions, water and light.Know More
In hypogeal germination, the cotyledons emerge from the seed containing enough nutrients to fuel seed development and are not photosynthetic. These seeds are usually larger than epigeal seeds. As the seedling grows, its shoot rises above ground level, while the cotyledons remain below or at ground level.
In epigeal germination, the cotyledons emerge and rise above ground level as the seedling grows. They may also serve a photosynthetic role in seedling development. Seedlings that develop this way quickly form a shoot and leaves, both of which perform photosynthesis to fuel further development.Learn more about Science
Seed germination begins when the first root breaks through the seed wall and ends when the first pair of true leaves begin the process of photosynthesis. The three stages in-between are when the primary root, which is called the radicle, develops root hairs, the first young shoot rises emerges from the soil and the first pair of true leaves form to begin to manufacture food for the plant.Full Answer >
Acid rain with a pH of 1.0 and lower affects seed germination by delaying the germination process. Some seeds are more resistant to the effect of acid rain than others.Full Answer >
Factors that can affect the germination of mung bean seeds include a lack of water, a lack of favorable temperature, infertile soil, a lack of fertilization and a lack of light. Seeds do not germinate if planted in such conditions.Full Answer >
A seed is a small embryonic plant that is enclosed in a seed coat; a nut, on the other hand, is a hard-shelled fruit that contains a single seed. Some examples of seeds are sunflower seeds, sesame seeds, flax seeds and pumpkin seeds. Chestnuts, acorns and hazelnuts are some examples of true nuts.Full Answer >
