Question

What is common in vegetative propagation of the modified stems of potato, ginger and sugarcane?

Answer 1

Hint:Vegetative propagation is asexual method of reproduction in plants. Vegetative propagation of the modified stems of potato, ginger and sugarcane is by bud.

Complete answer:
Asexual reproduction is the production of new plants from existing plants without the involvement of gametes. Asexual reproduction in plants can take place by the following methods-
a) Vegetative propagation
b) Budding
c) Fragmentation
d) Spore formation
- Vegetative propagation of the modified stems of potato, ginger and sugarcane is by vegetative bud. Vegetative buds are normally present on the stems and branches of plants. Vegetative buds are also present on the modified underground stems of plants like potato etc.
- Vegetative propagation involves the growth and development of one (or more) buds on the old part of the plant to produce a new plant. These buds are in dormant state in old parts of the plant.
- The common thing in the vegetative propagation of the modified stems of potato, ginger and sugarcane is that they all have buds in their nodes that give rise to new plants.
Each potato plant produces many tubers, each tuber has more than one bud. This method of producing potatoes, ginger and sugarcane is much faster.

Note:Students can take potato tubers and they can see buds on tubers. Students can also take a cut tuber with bud on it and cover it under the soil and thus students can grow potatoes. This activity can be done by using ginger and sugarcane.
