Answer 1

Answer:

For food storage, support, respiration, and moisture

Explanation:

Here are four reasons for root modifications.

1. For food storage

Examples are the roots of turnips, carrots, and sweet potatoes (Fig.1).

2. For better respiration

Plants like Rhizophora that grow in swampy areas have roots that grow upwards for respiration (Fig. 2).

3. For support

For example, the roots of the banyan tree develop in its branches. They grow down to the ground and support the tree (Fig. 3).

4. To obtain moisture

Flowers like orchids have roots that develop on the trunks and branches of trees. They hang freely and absorb moisture from the air (Fig 4).
