What is a plant callus in tissue culture?

In plant tissue culture, what term describes the inherent capacity of a single plant cell to divide and differentiate into an entire plant?

A scientist wants to produce virus-free plants in tissue culture. Which part of the plant will he use as an explant? (a) Mature stem (b) Axillary meristem (c) Apical meristem (d) Mesophyll cells Choose the correct option from the following:

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). IAS Gyan Assertion (A): To generate only a part of the plant from a cell is totipotency. Reason (R): Suitable specialized nutrient media and sterile conditions are required in 'in vitro' conditions for the division of cells in explants.

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Meristems are grown 'in vitro' to obtain virus-free plants from an infected plant. Reason (R): If a plant is infected with a virus, the apical and axillary meristems are free of virus.

In plant tissue culture, an explant is transferred into a nutrient medium that must primarily contain which of the following substances for proper growth and differentiation?

In plant tissue culture, the explant is transferred into a nutrient medium that primarily contains which essential components for growth and differentiation?

In plant tissue culture, what would you call the parenchyma cells that are made to divide under controlled laboratory conditions?

Assertion (A): To generate a whole plant from any cell/explant is called totipotency. Reason (R): Suitable special nutrient media and sterile conditions are required in 'in vitro' conditions for the division and growth of cells in explants. Choose the correct option:
