Question

A certain tissue, of a plant, infected with TMV was used to obtain a new plant using tissue
culture technique. Identify the technique used and reason out the possibility of obtaining a
new healthy plant.

Answer 1

Meristematic tissues actively divide cells.They divide at a very fast rate which inhibits the viral replication.So meristematic cells are devoid of any infection thus plants obtained do not have any infection.

Answer 2

Answer:

A tissue of a tobacco plant infected with tmv can be used to obtain a new plant by using shoot apical meristem of the plant and the technique that can be used for such growth is plant tissue culture. A shoot apical meristem is a region where differentiation of the cells does not takes place.
