Epigeal germination
In this type of germination where the cotyledons come above the soil surface into air and light, due to rapid growth and elongation of hypocotyl. The cotyledons are green and make food to be used by stem during growing season. They finally dry off and seedlings become independent e.g. bean, gourd, castor, cotton etc.
See my time lapse of French bean as this shows an example of hypogeal germination.
