Question

Recovery of healthy plants from diseased plants is possible by

• A. Tissue culture
• B. Meristem culture
• C. Ovary culture
• D. Pollen culture

Answer 1

The correct option is B

Meristem culture

The correct option is B.

Explanation of the correct option:

1. Meristem culture refers to a process in which virus-free meristems are cultured( both apical and axillary) that are used to get virus-free plants by rapid multiplication.
2. In this culture, at first virus-infected plants are treated with thermotherapy, and chemotherapy and shoot tips are collected.
3. Then surviving meristems are regenerated.
4. The regenerated plants are hardened in insect-proof conditions and tested for viruses.
5. This is an effective method for eliminating plant viruses.

Explanation of the incorrect options:

Option A:

Tissue culture refers to a process in which both plant and animal tissues are developed in vitro conditions.

Option C:

Ovary culture is also an in vitro procedure for growing new plants from unpollinated flowers.

Option D:

Pollen culture describes a method in which haploid plants are produced by culturing pollen grains on artificial media.

Final answer: Recovery of health plants from diseased plants is possible by meristem culture.
