Question

Grafting is a method of
A) Artificial vegetative propagation
B) Sexual reproduction
C) Artificial pollination
D) Cross-pollination

Answer 1

Grafting is a type of horticultural technique in which tissue parts of two or more plants are joined together to form a single plant. This way they grow as a single plant.

Complete answer:
Grafting is a form of tissue regeneration whereby a part of one plant (bud) also known as scion is placed on the stem, root or branch of another plant which is known as stock. This way a union takes place and the both the partners grow together. The stock part provides the root and the added part is called the scion. If a middle piece is added, it is called an interstock. Grafting is therefore a method of artificial vegetative propagation.

Let us analyze the options to find out the correct option.
Option A: Grafting is a method of artificial vegetative propagation. Therefore, this is the correct option.
Option B: Sexual reproduction is the fusion of a male and female gametes. Therefore, this is an incorrect option.
Option C: Artificial pollination is a mechanical pollination carried out by humans. It is done when the natural pollination process is undesirable. Therefore, this is an incorrect option.
Option D: Cross pollination is when a flower of one plant is pollinated with pollen of another flower or plant by wind, water or insects. Therefore, this is an incorrect option.

Hence the correct answer is option (A) Grafting.

Note: Grafting is a method used in horticulture to repair injured trees and plants, to make plants resistant to certain pests and diseases, to adapt to adverse conditions, to ensure pollination for producing multi flowered plants, etc. Grafting is used as a growth control method in ornamental plants like Roses.
