Question

Which plant hormone is named anti-ageing hormone?

Answer 1

Hint: This hormone naturally synthesised in a region where rapid cell division occurs, for example, developing shoot buds, root apices, young fruit, etc. It has a specific effect on cytokinesis.

Complete answer:
The hormone is a chemical signal that coordinates the various parts of the organism. These hormones are produced in one part of the body and then sent to another part of the body, where a response is triggered. Similarly in plants, the hormones are produced by the cell in one area and then transported to another area of the plants. There are five different types of hormones that are present in plants such as auxins, gibberellins, cytokinins, ethylene, and abscisic acids.
Auxins:
Produced by growing apices of the stem and root.
Helps in initiating rooting in the stem cutting.
Helps to prevent leaf and fruit drop in the early stage.
Gibberellins:
Increase in the length of the axis
Delay senescence
Helps in elongation of fruit and improves the shape of fruit like apple.
Cytokinins:
Stimulate growth and have an anti-ageing effect
Combine with auxin and helps in cell differentiation and growth of stem and root.
Helps in growth and development of the chloroplasts.
Ethylene:
Break seed and bud dormancy
Promotes senescence and abscission of the plant organs especially flowers and leaves.
In deep water rice plants, promote the elongation of internode/petiole.
Abscisic acid:
Inhibits seed germination
Increase the tolerance of plants from various kinds of stresses.
Role in seed development, maturation and dormancy.
Hence, by knowing the different roles and functions of different hormones in plants, we can say that cytokinins are named as anti-ageing hormones.

Note: In some parts of plants, cytokinins produced the anti-ageing effect. It provides a healthier and young look to the plants. Due to this effect, cytokinins are used by many florists to give a fresh look to the cut flowers. They also slow down the ageing process and provide much prettier flowers for a longer time.
