WebHypocotyl. Epicotyl. The portion of the embryonal axis which lies below the cotyledon in a dicot embryo is known as the hypocotyl. The portion of the embryonal axis which lies above the cotyledon in a dicot embryo is known as the epicotyl. It terminates with the radicle. It terminates with the plumule. WebDuring embryonic development, epicotyl refers to the portion of the embryonic axis that is between the plumule and the point of attachment of the cotyledons. An embryonic or seedling stem’s portion above the cotyledon is referred to as the hypocotyl. With almost all plants, the epicotyl eventually develops into the plant’s leaves.

Difference Between Epicotyl and Hypocotyl

WebThe main difference between hypocotyl and epicotyl is that, epicotyl is the part of embryonal axis which exists just above the cotyledonary node and ends with plumule on … WebIn hypogeous germination, the hypocotyl remains short and the cotyledons do not emerge from the seed but rather force the radicle and epicotyl axis to elongate out of the seed coat. The seed, with the enclosed cotyledons, remains underground, and the epicotyl grows up through the soil. my view on cheating in examination

WebJun 8, 2024 · Therefore, as the epicotyl pushes through the tough and abrasive soil, the plumule is protected from damage. Upon exposure to light, the hypocotyl hook straightens out, the young foliage leaves face the sun and expand, and the epicotyl continues to elongate. During this time, the radicle is also growing and producing the primary root. WebIn epigeous growth, the hypocotyl elongates, pulling the plumule and cotyledons above ground; in hypogeous growth, the cotyledons remain below ground because the epicotyl grows faster than the hypocotyl and pulls the plumule erect.
