Options

(a) Induction of cell division and delay in senescence
(b) To take part in cell division
(c) Refers to cell movements
(d) To cause dormancy

Correct Answer:

Induction of cell division and delay in senescence

Explanation:

The cytokinin is a true cell division factor, promotes meristematic tissue regions. The cytokinin prevents distruction of chlorophyll in leaves. In presence of kinin the rate of mitotic cell division gets increased. Under this effect when green leaves are kept in cytokinin solution then they become green for long time. So this effect of cytokinin is called as Richmond-Lang effect of senescence.
