Answer 2

Callus is defined as (d) an unorganised actively dividing mass of cells maintained in a culture.

• Callus deliberately divides the mass of cells preserved in culture. It has a meristematic cell providing enough cytoplasm to cause cell division.
• The growth hormones are used to enable the division and differentiation of the cells.
• When treated with auxin, the callus promotes rooting and when treated with cytokinine it stimulates cell maturation, differentiation and ultimately promotes stem growth.
