What Does Water Uptake Mean

Plant water uptake, or transpiration, represents the process by which water in soil is drawn into plants and returned in gaseous form to the atmosphere through leaf stomata.

How does a plant uptake water?

Plants absorb water through their entire surface – roots, stems and leaves. However, the majority of water is absorbed by root hairs. Root hairs are thin-walled uni-cellular outgrowths of epidermis. They are in close contact with the thin film of water surrounding the soil particles.

How do you find the water uptake?

A simple potometer is a piece of capillary tubing to which a plant has been connected. The water uptake is measured by recording the time taken for a bubble in the tube to move a set distance.
