Detailed explanation-1: -So the correct answer is (C). The option that is not a way plants control water loss is “plants have guard cells that leave stomata permanently open to regulate transpiration.”
Detailed explanation-2: -Leaves are covered by a waxy cuticle on the outer surface that prevents the loss of water. Plants that grow in dry environments and plants that grow on other plants (epiphytes) have a much thicker waxy cuticle than those growing in more moderate, well-watered environments (Figure 17.1.
Detailed explanation-3: -Internal factors that affect transpiration rates The leaf area influences the rate of transpiration. The wider the leaf area, the greater the rate of transpiration because wide leaves tend to have more stomata [5].
