Question

How does chemical coordination occur in plants?

Answer 1

Chemical coordination

1. Chemical coordination occurs in plants with the help of fluids secreted in plants known as phytohormones or plant hormones.
2. These hormones regulate the growth of plants.
3. For example, auxin is responsible for the growth of plants and cytokinin helps in cell division in the fast-growing parts of the plant.
4. Ethylene acts as a growth promoter as well as an inhibitor. Occurs in gaseous form. It is synthesized in the ripening fruits and tissues undergoing senescence.
5. Abscisic acid inhibits plant metabolism and regulates abscission and dormancy.
6. Giberllin promotes bolting, i.e. sudden elongation of internodes just before flowering in rosette plants like cabbage, beet
