Question

Which among the following is NOT an artificial method of vegetative propagation in higher plants?

• A. Grafting
• B. Micropropagation
• C. Budding
• D. Fragmentation

Hint:

Artificial vegetative propagation involves human intervention; natural methods occur without it.

Answer 1

The Correct Option is D

Step 1: Understanding vegetative propagation.
Vegetative propagation is a type of asexual reproduction in plants where new plants are produced from vegetative parts such as stem, root, or leaf.
Step 2: Artificial methods.
Artificial vegetative propagation methods are techniques developed by humans, such as grafting, budding, and micropropagation, to produce plants with desired traits.
Step 3: Natural method explanation.
Fragmentation is a natural method of asexual reproduction where the plant body breaks into fragments, and each fragment grows into a new individual.
Step 4: Analysis of options.
(A) Grafting: Artificial method.
(B) Micropropagation: Artificial tissue culture technique.
(C) Budding: Artificial horticultural practice.
(D) Fragmentation: Natural method, not artificial.
Step 5: Conclusion.
Fragmentation is not an artificial method of vegetative propagation.
