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.

Answer 2

Answer:

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.
