Ans. Is air spaces , (d)

Answer 2

Roots respire through air spaces because the roots of a plant also need oxygen which they obtain from the air spaces in the soil. If you give too much water to a plant in a pot you could kill the roots by drowning them! This is so that they can carry air from the atmosphere down to the root tips to be able to respire under water.
