WebWhen stomata are open, however, water vapor is lost to the external environment, increasing the rate of transpiration. Therefore, plants must maintain a balance between efficient photosynthesis and water loss. Plants have evolved over time to adapt to their local environment and reduce transpiration (Figure 5).

WebJul 30, 2024 · These hairs reflect sunlight and block wind movement, both of which reduce evapotranspiration from the leaves. Narrow and Pointed Leaves Plants like the Joshua tree have narrow, pointed, and sharp leaves whose reduced surface area protects the plant against water loss. Thick Leaves WebStep 2: Explanation of option ‘ (A)’. Spiny leaves do not increase the rate of transpiration in plants. Instead, these spiny leaves lower the transpiration rate. These spines possess thick cuticles and reduced surface area, and hence the rate of transpiration reduces significantly. Thus, spiny leaves do not increase transpiration.

WebJul 16, 2024 · How can sunken stomata reduce the amount of water lost through transpiration? Sunken stomata, which are responsible for the accumulation of moisture in the substomatal air gaps and lead to a low diffusion gradient, hence lowering the transpiration rate.
