Question

What hormone delays senescence?

Answer 1

Senescence:

1. Senescence is the process in which cells stop dividing because of old age but does not die.
2. Gibberellins are found in the stems of plants and are responsible for stem elongation.
3. Cytokinin is responsible for cell division in plants.
4. They are mainly responsible for cell growth and division.
5. Hence, gibberellins and cytokinin delay senescence.
