Question

What could increase the rate of water uptake by a shoot?

• A. Covering the shoot with a black plastic bag
• B. Covering the shoot with a clear plastic bag
• C. Providing more minerals in the soil
• D. Increased rate of transpiration

Answer 1

The correct option is D Increased rate of transpiration

Transpiration is a process by which the water is lost through the leaves from the structures called as stomata. The xylem cells make up a tube starting from the leaves, down the stem, till the roots. This creates a drinking straw from which the water travels from the roots to the leaves. Hence, if the rate of transpiration increase, the uptake of water from the roots and the shoots also increases.
