Question

Write short notes on the following:
(a) Micro propagation

Answer 1

Micro propagation is the propagation of plants by tissue culture technique.
Tissues of vegetative buds, shoot apex, or other suitable plant parts are used as an explant for micro propagation.
The explant is treated with sterilization chemicals to prevent microbial growth and is then cultured in a particular nutrient medium.
Cells grow and divide to form a cell mass called callus. Some growth regulators are added and callus differentiates into plant parts looking like a tiny plant called plantlets. After \(4-6\) weeks these plantlets are transferred to the soil.
