Q. Induction of cell division and delay in senescence are due to :
- Gibberellin
- Auxin
- Cytokinin
- Ethylene
Solution :
Correct option : C Cytokinin is a plant hormone. It plays major role in cell proliferation and cell division. It also delays the destruction of chlorophyll and protein. During senescence, cytokinin levels are low. It delays in senescence of leaves when sprayed externally by delaying the destruction of chlorophyll and proteins in leaves. So, the correct answer is ‘Cytokinin’
