Consider the following statements regarding reproduction in plants and choose the appropriate answer.
I. Totipotency of cells enables the human being to micropropagate desired plants.
II. The genetic constitution of a plant is not affected in vegetative reproduction/ propagation.
III. Rhizome in ginger and Curcuma are-considered organs of vegetative propagation.

Question

Q. Choose the correct statement/s.
(i) The genetic constitution of a plant is unaffected in vegetative propagation.
(ii) Rhizome in ginger serves as an organ of vegetative reproduction.
(iii) Totipotency of cells enables us to micropropagate the plants.

Answer 1

Totipotency is the capacity or ability of any single plant cell to differentiate into entire new 'plant when providing with suitable growing medium. It enables us to micropropagate desired plants. In vegetative propagation, there is no genetic recombination, so the genetic constitution of a plant is not affected in vegetative propagation. In ginger and turmeric (Curcuma) the means of vegetative reproduction/propagation is fleshy dorsiventral, horizontal, branched underground perennial modified stem-(rhizome). Hence correct answer is option A.
