Question
The plant roots being underground respire by using which mechanism?

Answer
Roots of the plants respire under the ground. Root cells get oxygen from the air present in the space between the soil particles. There are several root hairs present on the roots of a plant. The oxygen from the air (between soil particle) diffuses into root hair and reaches to the cells of the roots. This oxygen is utilised for respiration.
