Botany and Plant Science

Corolla consists of petals, which can be of different colours.

Flower bears male and female reproductive parts which are involved in sexual reproduction.

Pistil or gynoecium bears ovary in a flower.

Scion is a cutting of young stem used for grafting.

Pollination involves transfer of gametes (pollens) from male reproductive part (anther) to female reproductive part (stigma) for fertilization.

Micropyle is an opening at the lower end of the ovule.

Radicle is a part of embryo of plants.

Pollination is the process of transfer of pollen grains from anthers to stigma of flower.

Plumule is a part of embryo that gives rise to shoots.

Radicle of embryo give rise to roots and thus forms the root system of the plants.

Self pollination does not produce variation in plants but leads to genetic uniformity.

Pistil develops pollen tube when pollen reaches stigma.

Stomata are minute apertures on plants, found typically on the outer leaf skin. 

The stem of cactus plant is very fleshy, it stores water and uses it very slowly in dry conditions.

Kranz anatomy (mesophyll is divided into spongy parenchyma and bundle sheath cells) is the characteristic of C4 plants.
