What is the difference between a hypocotyl and an epicotyl?

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. Epicotyl develops into the upper part of the stem, which bears leaves, flowers, and fruit.

What is difference between hypocotyl and radicle?

1) hypocotyl is the part of an embryo plant beneath the stalks of the seed leaves or cotyledons and directly above the root while radicle is the embryonic root. 2) hypocotyl develops into the first part of the stem from which the root will develop while radicle grow downward in the soil to form root.

What is the difference between epicotyl and cotyledon?

As nouns the difference between epicotyl and cotyledon is that epicotyl is (botany) in plants with seeds, that portion of the embryo or seedling above the cotyledons while cotyledon is (botany) the leaf of the embryo of a seed-bearing plant; after germination it becomes the first leaves of the seedling.

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.

What is epicotyl and hypocotyl germination?

Hint: Epicotyl is the first part of the plant that emerge after the germination, where as it is important in the beginning stage of the plant life, whereas hypocotyl is the structure that can be observed in the seedling after the germination.

What is difference between integument and testa?

An integument is an outer covering of the ovule. Testa is an outer covering of the seed. It is a pre-fertilization product. The cells of the testa are dead.

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.

Which grows faster epicotyl or hypocotyl?

In 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.

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 does the hypocotyl do?

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 role of epicotyl?

What is tegmen and testa?

The main difference between testa and tegmen is that testa is the outer seed coat whereas tegmen is the inner seed coat. Furthermore, testa is smooth, thick, impermeable, and may be colored while tegmen is a thin membranous and hyaline.

What is the difference between epicotyl and hypocotyl in dicot?

The 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 ther hand hypocotyl is part of embryonal axis which is just below the cotyledonary node in Dicot embryo. Differences between epicotyl and hypocotyl in Dicot seed

What do you mean by hypocotyl?

Hypocotyl definition in biology: the portion of embryonal axis which lies below the cotyledon and present between the radicle and cotyledonary node in a Dicot embryo is known as hypocotyl and terminate with radicle.

What is hypogeal and epicotyl germination?

The cotyledons of the hypogeal germination are below the ground. Examples are as Pea, Runner bean, Eutacta, Mango, Maize, Rice. The hypocotyl part of the germinating seedling lies above the ground, whereas the epicotyl part lies below the ground.

What is the hypocotyl and radicle?

The hypocotyl is the part of the seedling stem found between the cotyledons and the radicle. It is the main elongation part of the plant, which ultimately develops into the first part of the stem. The radicle is the part occurs at the end of the hypocotyl, which develops into the root.
