Botany and Plant Science

Both POP2 and POP3 are the genes directing pollen tube to ovule.

In basal placentation, the placenta develops at the base of ovary and a single ovule is attached to it, as in sunflower and marigold.

Radicle is enclosed in a sheath called coleorhiza

Fabaceae; Inflorescence is racemose. Flower is bisexual, zygomorphic.

In conjoint type of vascular bundles, the xylem and phloem are situated at the same radius of vascular bundles. Such vascular bundles are common in stems and leaves.

There are five petals, the largest (standard) overlaps the two lateral petals (wings), which in turn overlap the two smallest anterior petals (keel); this type of aestivation is known as vexillary.

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.

It is said to be the other generation of plant.
