These cells regulate the opening and closing of the stoma by either inflating and opening when there is high water content in the leaf, or collapsing and closing the stoma when water content in the leaf is low. Sunken stomata are commonly found in plants in arid environments as one of their adaptations to preserve water. Transpiration normally takes place in the presence of Sunlight. Coniferous type stomata are sunken. Bookshelf Stomata are altogether absent or if present they are vestigeal. 2. Thicker the cuticle, the lower the transpiration. How does humidity affect the evaporation rate? Boundary layers increase as leaf size increases, reducing rates of transpiration as well. 5. This is an adaptation to check excessive transpiration in these plants. Transpiration is the loss of water In the form of water vapour from the leaves of the plant.
