Question

A small piece of root tissue was taken from a rose plant and placed in a nutritive medium, each tissue grow a ne rose plant, what reproductive process is this? what type of genes will be possessed by rose plant?

Answer 1

This type of tissue culture where whole plant could be generated from any part of plant in special nutritive media is called totipotency.

Type of genes possessed by rose plant will be identical and are called somaclones.

Answer 2

Solution:

This process is known as totipotency and the gene possessed by the rose plant is a somaclonal gene.

Explanation:

• It has been observed that a cell is capable of undergoing development like the zygote, which is capable of developing into a normal embryo under a suitable environment.
• This capacity of the cell is known as totipotency.
• When a small piece of root tissue is placed in a nutritive medium a new plant is grown because of totipotency.
• In this, the rose plant possesses somaclonal genes.
