Botany and Plant Science

In whip grafting, both stock and scion are cut obliquely at about the same angle.

This flower possesses some mechanical barrier on their stigmatic surface to avoid self pollination, presence of gynostegium and pollinia in caleotropis.

Here anthers matures before stigma.

Coleoptile is the pointed protective sheath covering the emerging shoot in monocotyledons such as grass. It is also called plumule sheath.

Sieve tubes are the specialised cells of phloem.

It is the study of flowers.

A seed is an embryonic plant enclosed in a protective outer covering.

It is the study of arrangement of flowers on peduncle.

In this, the formation of embryo takes place from any other cell of the embryo sac.

It is said to be the other generation of plant.

It is a plant in which both male and female sex organs occur in the same flower.

Opposite the micropylar end, is the chalaza, representing the basal part of ovule.

A typical angiosperm embryo sac, at maturity, though 8-nucleate is 7-celled. The large central cell has two polar nuclei.

Epicotyl has a shoot apex and a few leaf primordia enclosed in a hollow foliar structure, the coleoptile.

Seedless bananas and grapes are triploids.
