What is the epicotyl and radicle?

The epicotyl (region above the cotyledon) gives rise to the stem and leaves and is covered by a protective sheath (coleoptile). ... The radicle gives rise to the roots, the hypocotyl to the lower stem, and the epicotyl to the leaves and upper stem.

What type of roots do peanuts have?

Peanut plants have a typical dicotyledonous root system with a single taproot branched by the formation of first-, second- and third-order lateral roots (Fig. 1).

What is the shape of peanut seed?

The spheroidal shape in mature seeds was present in 8 cultivars, the shortbroad form in 4, elongated-slender in 12, cylindrical-tapered end in 10 cultivars, and only one cultivar was cylindrical-blunt ended (Figure 4).

What is the epicotyl of a seed?

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. ... In plant physiology, the epicotyl is the embryonic shoot above the cotyledons.

What is radicle and Plumule?

The plumule is the rudimentary embryonic shoot that grows from the seed after germination. ... Radicle is the embryonic root that grows from the seed. It is the first part to emerge from the embryo through the micropyle of the seed and is the embryonic root that later develops into the root system of the plant.

What is called radicle?

In botany, the radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination. The radicle is the embryonic root of the plant, and grows downward in the soil (the shoot emerges from the plumule). ... Radicles in seedlings are classified into two main types.

Is peanut a stem or root?

Answer: It is a fruit.

What are the characteristics of peanut?

The oblong pods have rounded ends and are most commonly 25–50 mm (1–2 inches) long with two or three seeds; the pods are contracted between the seeds and have a thin, netted, spongy shell. The seeds vary from oblong to nearly round and have a papery seed coat that ranges in colour from whitish to dark purple.

Are peanuts grown underground?

Many people are surprised to learn that peanuts grow beneath the soil and do not grow on trees like pecans or walnuts. Below you'll discover how peanuts grow, from preparing the soil for planting to the peanut harvesting process.

How are peanuts seeds dispersed?

Such seeds are dispersed readily by such, natural means as wind, water, animals, and birds. ... The natural means of dispersal have been lost long since by most of our cultivated seed crops, like the cereals, beans, and peanuts.

Is a peanut fleshy or dry?

This type of fruit structure is characteristic of peas, beans and peanuts. The peanut is one of the few legumes that does not split open when ripe. This is probably because the fruit of the peanut develops in the soil rather than in the air. The capsule is another type of dry dehiscent fruit.

Why is groundnut not a nut?

The peanut belongs to the botanical family Fabaceae (or Leguminosae), commonly known as the legume, bean, or pea family. ... The botanical definition of a nut is "a fruit whose ovary wall becomes hard at maturity". Using this criterion, the peanut is not a nut.

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.

Is the epicotyl part of the plumule?

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 part of the plant does the radicle grow into?

root anatomy and function

The primary root, or radicle, is the first organ to appear when a seed germinates. It grows downward into the soil, anchoring the seedling. In gymnosperms and dicotyledons (angiosperms with two seed leaves), the radicle becomes a taproot.
