What is an Epicotyl and hypocotyl?

An epicotyl, which extends above the cotyledon(s), is composed of the shoot apex and leaf primordia; a hypocotyl, which is the transition zone between the shoot and root; and the radicle.

What is the difference between Epicotyl and Plumule?

The key difference between epicotyl and plumule is that epicotyl is the part of the embryonic axis which lies above the point of attachment of cotyledons while plumule is the tip of the epicotyl which gives rise to the shoot of the new plant. The seed is the ripened ovule which contains the embryo.

What is the function of the 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. Most seed-bearing plants have hypocotyls, but the grasses have different, specialized structures.

What is hypocotyl example?

In some plants, the hypocotyl becomes enlarged as a storage organ. Examples include cyclamen, gloxinia and celeriac. In cyclamen this storage organ is called a tuber.

What is the function of Epicotyl?

An epicotyl is important for the beginning stages of a plant's life. It is the region of a seedling stem above the stalks of the seed leaves of an embryo plant. It grows rapidly, showing hypogeal germination, and extends the stem above the soil surface.

What is cotyledon hypocotyl?

In the developing embryo, the hypocotyl is the embryonic axis that bears the seedling leaves (cotyledons). In plant development: Origin of the primary organs. … other four will form the hypocotyl, the part of the embryo between the cotyledons and the primary root (radicle).

What is Coleoptile and Coleorhiza?

Coleoptile refers to a sheath protecting a young shoot tip in grass or cereal while coleorhiza refers to a sheath protecting the root of a germinating grass or cereal grain.

Is Epicotyl a Plumule?

The part of the embryonic axis that projects above the cotyledons is known as the epicotyl. The plumule is composed of the epicotyl, young leaves, and the shoot apical meristem. Upon germination in dicot seeds, the epicotyl is shaped like a hook with the plumule pointing downwards.

What is the function of radicle?

(a) Radicle: The radicle is the embryonic root of the plant,and grows downward in the soil. It is the first thing to emerge from a seed and down into the ground to allow the seed to suck up water and send out its leaves so that it starts photosynthesizing.

What does Epicotyl mean?

: the portion of the axis of a plant embryo or seedling above the cotyledonary node.

What is the function of Testa?

The testa of higher plant seeds protects the embryo against adverse environmental conditions. Its role is assumed mainly by controlling germination through dormancy imposition and by limiting the detrimental activity of physical and biological agents during seed storage.

What is the function of Plumule?

Complete answer: Function of Plumule (shoot tip): The plumule is the part of the embryo that develops into the shoot bearing the leaves of the plant. The plumule gives rise to aerial shoots. The function of cotyledon: They store reserve food material or serve as photosynthetic organs in young seedlings.
