Detailed explanation-1: -Epigeal germination implies that the cotyledons are pushed above ground. The hypocotyl elongates while the epicotyl remains the same in 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.

Detailed explanation-2: -Epigeal Germination: In this type of germination, the cotyledons are pushed upwards above the soil into the air and light due to the rapid growth and elongation of the hypocotyl. For example, bean, cotton, castor, papaya, onion, and tamarind.

Detailed explanation-3: –Examples of epigeal germination are cotton, sunflower, castor, and bean (or common bean).-As epigeal germination plants are more vulnerable to grazing and weather conditions, the plants produce a large number of seeds as an evolutionary strategy.
