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 difference between Epicotyl and hypocotyl?

The difference between the hypocotyl and epicotyl is explained below. The part of the embryonal axis which exists below the cotyledon in a dicot embryo is called the hypocotyl. The part of the embryonal axis which exists above the cotyledon in a dicot embryo is known as the called epicotyl.

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 difference between a Plumule and a radicle?

(a)Radicle and plumule. Plumule is the embryonic shoot of the plant. Radicle is the first part of the seedling. ... The radicle makes the root of the plant.

What is the Plumule?

1 : the primary bud of a plant embryo usually situated at the apex of the hypocotyl and consisting of leaves and an epicotyl. 2 : a down feather.

What is the function of 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 the purpose of the 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.

Why does the Plumule grow upwards?

In seeds like the bean and the pea, the plumule grows out slightly bent so that the first green leaves are not damaged by anything lying on top of the seed. Once in the air the plumule continues to grow upwards and straightens out so that the first green leaves are facing the light.

Why are Coleoptile and Coleorhiza only present in monocots?

Monocots have single cotyledons whereas dicots have two cotyledons in them. Coleoptile and Coleorhiza are important in the monocots so as to protect the plumule and radical respectively. Coleoptile encloses the shoot apex and the leaves within it and when they grow out of the seed through the soil, it protects them.

What is the function of Epicotyl and hypocotyl?

(Top) In a corn seed (monocot), nutrients are stored in the cotyledon and endosperm tissue. The radicle and hypocotyl (region between the cotyledon and radicle) give rise to the roots. The epicotyl (region above the cotyledon) gives rise to the stem and leaves and is covered by a protective sheath (coleoptile).

What comes first radicle or Plumule?

Plumule comes out after the radicle. Radicle is the first to appear from the seed, followed by the plumule. Plumule grows on to become the shoot of the plant, into its stem and leaves. Radicle grows on to become the root system of the plant.

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.
