Detailed explanation-1: -On a hot, dry day, the guard cells of plants close their stomata to conserve water. What impact will this have on photosynthesis? Levels of carbon dioxide (a necessary photosynthetic substrate) will fall. As a result, the rate of photosynthesis will decrease.
Detailed explanation-2: -A reflective cuticle will reduce solar heating and temperature rise of the leaf, helping to reduce the rate of evaporation. Tiny hair-like structures called trichomes on the surface of leaves also can inhibit water loss by creating a high humidity environment at the surface of leaves.
Detailed explanation-3: -Waxy cuticles, trichomes (leaf hairs), sunken stomata, and other leaf adaptations also help reduce transpiration rates by keeping the leaf surface cool or protecting it from air currents that increase evaporation.
