Question

Roots are used in the vegetative propagation of
A: Ginger
B: Chrysanthemum
C: Sweet potato
D: Potato

Answer 1

Hint: Plants use their leaves, roots, and stems for vegetative propagation, which is an asexual method of reproduction. This can happen as a result of plant fragmentation and regeneration of particular vegetative sections. Vegetative propagation is often referred to as cloning. Asexual reproduction is possible thanks to meristem tissue. It consists of undifferentiated cells that are actively dividing, allowing for plant growth and giving rise to plant tissue systems.

Complete answer:
Option A:
The rhizome is used to spread ginger. Rhizomes are underground stems that grow horizontally. The underground stems of ginger are bloated with food reserves. The terminal bud develops into a flowering shoot, while the lateral buds develop into new plants.
So, option A is incorrect:
Option B:
A lateral branch that emerges from the main stem near the ground level moves a short distance underground. A sucker is the name for this branch. It comes to a halt at the end of its journey and produces adventitious roots in the ground as well as shoots above ground, resulting in the formation of a new plant. Suckers are used to propagate chrysanthemums, which are primarily grown for their beautiful flowers.
So, option B is incorrect.
Option C:
Sweet potato roots are used in vegetative propagation. When buried in moist soil, the roots produce adventitious buds from which new plants can emerge. Reproductive roots are the name for these types of roots.
So, option C is correct.
Option D:
Potatoes are propagated vegetatively, which means they are grown from small tubers. Farmers can cut tubers into several pieces to increase their planting stock. Within a few days, new plants emerge from the buds. If a potato like this is planted in soil, it may develop into a full plant.
So, option D is incorrect.

Hence, Option C is the correct answer.

Note:
Plants use their leaves, roots, and stems for vegetative propagation, which is an asexual method of reproduction. This can happen as a result of plant fragmentation and regeneration of particular vegetative sections. The formation of adventitious roots will aid natural vegetative propagation. As a result, new plants can emerge from the parent plant's roots, stem, and leaves. Humans carry out Artificial Vegetative Propagation in fields and laboratories. Grafting, cutting, tissue culture, and other forms of artificial vegetative reproduction are the most common.
