Which adaptation assists temperature regulation in plants? (A) Large leaves for cooling (B) Increased production of seeds (C) Movement of glucose to roots (D) Evaporation of water from stomates - HSC - SSCE Biology - Question 6 - 2004 - Paper 1

The evaporation of water from stomates, also known as transpiration, plays a significant role in temperature regulation in plants. During transpiration, water is lost from the plant's surface through tiny openings called stomata, primarily located on the leaves.

As water evaporates, it absorbs heat from the plant and the surrounding air, leading to a cooling effect. This process helps maintain an optimal temperature within the plant, allowing it to function efficiently and preventing overheating. Therefore, the correct adaptation that assists in temperature regulation in plants is:

(D) Evaporation of water from stomates.
