The evolutionary driving forces leading to sunken or 'hidden' stomata whose antechambers are filled with hairs or waxy plugs are not fully understood. Question 28 Succulents are known to keep their stomata closed during the day to check transpiration. Stomatal transpiration accounts for between 50-and 97% of total transpiration. The correct answer, step by step is: Nerium has stomata that are sunken below the leaf surface to regulate the rate of transpiration. An official website of the United States government. (a) Stomatal transpiration : Stomata remain open during the day so that CO 2 can diffuse in to enable photosynthesis. So, in order to reduce the excessive transpiration, the size of stomata of leaves is reduced in some plants, or they are covered by thin hairs. They have an extensive root system to absorb the maximum amount of water. Stomata are found distributed only on the upper surface of leaf, e.g., water lily, Nymphaea and many aquatic plants. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. Sunken, covered, and encrypted stomata have been anecdotally linked with dry climates and reduced transpiration and therefore have been used to infer dry palaeoclimates from fossils. 3.
