Question

1. Ginger is consider to be a stem , not a root. Why ?

2. Write a brief account on pollination.​

Answer 1

Ginger is a rhizome. It is a modified stem of a plant that usually grows horizontally underground. It generally has roots and shoots arising from its nodes. The root is a part of a plant that bears no leaves and therefore lacks nodes. Hence, ginger is a stem, not root.

Pollination:

Pollination is very important. It leads to the creation of new seeds that grow into new plants.
