Answer 1

Answer:

The cells placed in the nutrient medium for tissue culture grow rapidly to form callus

Answer 2

'callus'

A small piece of plant tissue is taken from the growing point of the plant or from the tip of the plant and placed on a sterile jelly which contains nutrients and plant hormones. The hormones make the cells in the plant tissue divide rapidly producing many cells which forms a shapeless lump of mass called 'callus'.
