What is hypocotyl in plants?
What is hypocotyl in plants?
The hypocotyl (short for “hypocotyledonous stem”, meaning “below seed leaf”) is the stem of a germinating seedling, found below the cotyledons (seed leaves) and above the radicle (root).
What is epicotyl in plants?
In plant physiology, the epicotyl is the embryonic shoot above the cotyledons. On so many plants the epicotyl will eventually develop into the leaves of the plant. In dicots, the hypocotyl is what appears to be the base stem under the spent withered cotyledons, and the shoot just above that is the epicotyl.
What is the hypocotyl chegg?
The hypocotyl is a part that is found between radicle and cotyledons. During the process of germination, the cotyledons behave like an absorptive organ. The formation of triploid endosperm takes place during the process of double fertilization.
What is the role of a hypocotyl?
The part of a plant embryo or seedling that lies between the radicle and the cotyledons. Upon germination, the hypocotyl pushes the cotyledons above the ground to develop. It eventually becomes part of the plant stem.
What is hypocotyl and epicotyl?
The hypocotyl refers to the part of the stem of an embryo plant beneath the stalks of the seed leaves or cotyledons and directly above the root while the epicotyl refers to the region of an embryo or seedling stem above the cotyledon.
What is the difference between Plumule and hypocotyl?
The hypocotyl refers to the part of the stem of an embryo plant beneath the stalks of the seed leaves or cotyledons and directly above the root. The plumule is the tip of the epicotyl which gives rise to the shoot of the new plant.
What is it called when hypocotyl elongates and rises above the ground?
The correct option is D. Epigeal germination. In Epigeal germination, the cotyledon rises above the ground after germinating. The cotyledons are brought above the ground due to elongation of the hypocotyl.
What is the difference between epicotyl and hypocotyl?
The main difference between hypocotyl and epicotyl is that the hypocotyl is between the cotyledonary node and the radicle whereas the epicotyl is between the plumule and the cotyledonary node.
What is the role of the hypocotyl?
What is meant by hypocotyl and epicotyl What is their significance?
the epicotyl is the embryonic shoot above the cotyledons. In most plants the epicotyl will eventually develop into the leaves of the plant. In dicots, the hypocotyl is what appears to be the base stem under the spent withered cotyledons, and the shoot just above that is the epicotyl.
What is the meaning of hypocotyl in science?
Science definitions for hypocotyl. hypocotyl. The part of a plant embryo or seedling that lies between the radicle and the cotyledons. Upon germination, the hypocotyl pushes the cotyledons above the ground to develop. It eventually becomes part of the plant stem.
What is the function of the hypocotyl during germination?
Upon germination, the hypocotyl pushes the cotyledons above the ground to develop. It eventually becomes part of the plant stem. Most seed-bearing plants have hypocotyls, but the grasses have different, specialized structures. The American Heritage® Science Dictionary Copyright © 2011.
What is a hopocotyl stem?
In the embryo, the hopocotyl is the rudimentary stem. The sprouts of some plants have an elongate hypocotyl that bears assimilative cotyledons. This type of aboveground germination characterizes hornbeam. In other plants the hypocotyl is underdeveloped, and the cotyledons do not appear on the surface.
What is the hypocotyl of a turnip?
In many root crops, including the turnip, carrot, and sugar beet, the hypocotyl consists of the fleshy part of the storage organ, which is found between the stem base and the root proper.
