Q. Consider the following statements and choose the correct option. 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 plants.
A) Statements I and II alone are true
B) Statements II and III alone are true
C) Statements II alone is true
D) All the three Statements I, II and II are true
Explanation
In vegetative propagation, there is no genetic recombination, so the genetic constitution of a plant is unaffected in vegetative propagation. In ginger (Zingiber officinale), the means of vegetative propagation is fleshy, dorsiventral, horizontal, branched, underground, perennial, straggling rhizome (modified stem). Totipotency is the capability of any plant cell to develop into entirely new plant when provided with the suitable growing medium. it enables us to micropropagate plants.
