What are the types of germination seeds.
How many are they?
There are two main types of germination in seeds:
1) Hypogeal germination: In this type, the cotyledon (seed leaf) remains below the ground after germination. The epicotyl (embryonic shoot) elongates and pulls the cotyledons and plumule (bud) above the soil surface. The cotyledons stay beneath the ground, and the first leaves emerge from the plumule. Examples include peas, beans, and peanuts.
2) Epigeal germination: In this type, the cotyledons are pulled above the ground soon after germination. The hypocotyl (part of the embryo connecting the radicle and cotyledons) elongates and pushes the cotyledons and plumule above the soil surface. The cotyledons become green and function as the first leaves. Examples include lettuce, sunflower, and tomato.
Therefore, there are two main types of germination seeds: hypogeal germination and epigeal germination.
