Question

Which of the following is NOT the significance of vegetative propagation?

• A. Variations are caused, which help in evolution
• B. The yield of plant can be increased by grafting
• C. Production of clones of economically useful and rare plants
• D. Easy and cheaper method of multiplication

Hint:

In vegetative propagation, there is no genetic variation. Clones are produced that are genetically identical to the parent plant.

Answer 1

The Correct Option is A

Step 1: Understanding vegetative propagation.
Vegetative propagation is a form of asexual reproduction where new plants are produced from vegetative parts such as roots, stems, or leaves. This method does not typically cause variations, as the offspring are genetically identical to the parent plant. Step 2: Analyzing the options.
(A) Variations are caused, which help in evolution: This is incorrect. Vegetative propagation produces clones, which do not involve genetic variation.
(B) The yield of plant can be increased by grafting: This is correct. Grafting is a form of vegetative propagation that increases yield.
(C) Production of clones of economically useful and rare plants: This is correct. Vegetative propagation is often used to propagate valuable plants.
(D) Easy and cheaper method of multiplication: This is correct. Vegetative propagation is generally cheaper and quicker than seed propagation. Step 3: Conclusion.
The correct answer is (A) Variations are caused, which help in evolution.
