Hey...there is your answer..
Epigeal germination implies that thecotyledons are pushed above ground. Thehypocotyl (part of the stem below the cotyledon) elongates while the epicotyl (part of the stem above the cotyledon) stays the same length. In this way, the hypocotyl pushes the cotyledon upward.
Normally, the cotyledon itself contains very little nutrients in plants that show this kind of germination. Instead, the first leaflets are already folded up inside it, andphotosynthesis starts to take place in it rather quickly

Answer:
Epigeal germination is the germination of a seed occurring above the ground level. In this type of germination, the hypocotyl develops to grow for the formation of a loop above the soil. It then clongates thereby pushing the cotyledons through the ground upwards.
