Answer 1

Answer:

Roots need oxygen

As mentioned above, roots respire too! One of the functions of the substrate is to serve as a site for air exchange between the root zone and atmosphere. In other words, roots breathe oxygen like we do. Different plants have different oxygen requirements for their root systems.

Answer 2

The roots of plants too respire to generate energy but they follow a different method. They take up air rich in oxygen from air spaces between the soil particles. The breathed in oxygen is supplied to the cells where it is used to break down glucose into carbon-dioxide and water. ... Energy is stored in the form of ATP.
