WebBoth of these adaptations help prevent water loss by trapping water vapour just above the surface of the leaf and above the stomata, creating a warm and saturated microclimate in the area, which means that there is less of a concentration gradient and so less evaporation and diffusion of the water out of the stomata pore. - Curled and spiny leaves. 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

What is the function of sunken stomata? - Quora

WebC 4 plants reduce the need to frequently open stomata by creating a high carbon dioxide concentration in the bundle sheath cells, which conduct the Calvin cycle. Regardless of photosynthetic pathway, plants can open and close stomata to regulate transpiration rate … WebDec 9, 2024 · Stomata of the rolled leaves will not be exposed to the wind, reducing the rate of transpiration further, reducing water loss. By reducing leaves to spines on some xerophytes, this greatly reduces the surface area of the leaf, which greatly reduces the amount of transpiration, helping assist in reducing water loss. dangers of flaxseed oil
