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: -1) In Epigeal germination cotyledons are pushed above the ground.
Detailed explanation-3: -Once the seedling reaches the light, the hook opens to create a straight seedling. This pattern is called epigeous. In the second pattern, the cotyledons remain underground and the stem (epicotyl) emerges above ground. This pattern is called hypogeous.
Detailed explanation-4: -In viviparous germination, the seeds germinate while they are still attached to the parent plant. Embryo grows out of the seed and out of the fruit. The seed projects itself in the form of a green seedling and the root and the hypocotyl.
Detailed explanation-5: -The type of germination in which hypocotyl elongates rapidly and arch upward pulling the cotyledons which move above the soil is called epigeal germination. Gourd and castor are examples of epigeal germination.
