3969.	Question :''Tissue culture is the best method for propagating rare and endangered plant species''. Discuss.
Answer» Solution :The growth of plant tissue in special culture medium under suitable controlled CONDITIONS is known as tissue culture. Micropropagation : (i)The regeneration of a whole plant from single cell, tissue or small pieces of vegetative structures through tissue culture is called micropropagation. (ii)This is one of the modern methods used to propagate plants. Advantages of modern methods : (i)Plants with desired characteristics can be multiplied rapidly in a SHORT duration. (iii)Tissue culture can be carried out in any season to PRODUCE plants. (iv)Plants which do not produce viable seeds and seeds that are diffcult to germinate can be PROPAGATED by tissue culture. (v)Thus this method is ideal to propagate rare and endangered plants. (vi) Disease free plants can be PRODUCED by meristem culture.

Discussion

3970.	Question : Tissue culture is the best method for propagating rare and endangered plant species .
Answer» SOLUTION :Micropropagation of pants invitrothought tissue culturing is a modern and alternative tool to conserve and safeguard RATE plant species . Since the basis principal behind PTC is totipotency. With the HELP of a single expant it is possible to gernerate a huge population of plantlets within a short span of TIME.
