It works like this. Fewer stomata: One of the other adaptations, in order to reduce excessive loss of water through transpiration, is that the leaves of certain plants have very less number of stomata. Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. The leaves may be covered by thick cuticle such as in Banyan tree, so as to reduce transpiration. Light Brown.

The stomata are typically sunken, occurring within the hypodermis instead of the epidermis. Pinus species, Cistus species, Solution:-The three adaptations in plants to reduce the transpiration are, 1. Pits create a pocket of moist air between the stomata and the epidermal surface, reducing the concentration gradient between the inside of the plant and the outside, reducing evaporation and preventing water loss. 0000000555 00000 n Stomata are typically found in plant leaves but can also be found in some stems. In addition, it bears a number of unique adaptive anatomical features. The leaves in hot or dry environments may be adapted to reduce transpiration. Found inside – Page 2042.2 of Chapter 2A on photosynthesis and will come back to it in Chapter 4A on the plant's energy balance. A special case where boundary layer conductance is expected to be very low is that of sunken stomata, where stomata are concealed ... In these plants the stomata are found embedded into the leaf layers rather than on the leaf surface.
