2. The cotyledons are brought out of the soil by the excessive growth of the hypocotyl.
3. The plumule remains enclosed and protected by cotyledons till it comes out of the soil.
4. The cotyledons become green and function as the first leaves of the seedling.

In botany, a seed is described as showing epigeal germination when the cotyledons of the germinating seed expand, throw off the seed shell and become photosynthetic above the ground. The opposite kind, where the cotyledons remain non-photosynthetic, inside the seed shell, and below ground, is hypogeal germination.
The terms epigean, epigeic or epigeous are used for organisms that crawl (epigean), creep like a vine (epigeal), or grow (epigeous) on the soil surface: they are also used more generally for animals that neither burrow nor swim nor fly.
