Write short note on : Tissue culture

Explanation

Tissue culture advanced technique by which new plants are grown by removing tissue or separating cells from the growing tip of a plant i.e., root apex or stem apex. This reglon has meristematic tissue. The cells from the growing tip of a plant are placed in an artificial medium containing growth promoting hormone. The cells divide rapidly to form a small cell mass called callus.
The callus is transferred to another medium containing hormones for growth and differentiation. The plantlets are placed in the soil so that they can grow into mature plants.
Advantages : (1) Many plants can be grown from one parent in disease-free conditions.
(2) This technique is commonly used for ornamental plants.
