Final answer:

Transpiration is the loss of water from plant stomata, influenced by environmental factors. Plants have developed adaptations to regulate transpiration effectively.


Explanation:

Transpiration: Transpiration is the loss of water from the stomata of plants. It creates a 'suction' or transpirational pull that is important for the movement of water through the plant. Transpiration is affected by environmental conditions e.g wind, temperature, humidity, and light intensity. The rate of transpiration is measured using a potometer. In order to prevent excessive transpiration, plants have developed adaptations such as thickened cuticle, position of stomata, hairs on leaves, reduction of leaf size, leaf spines, leaf arrangements, and rolling of leaves.
