WebThe stomata pores are regulated by surrounding guard cells which regulate the rate of transpiration. When guard cells become turgid they cause stomata to open allowing water to evaporate. When transpiration exceeds the absorption of water by a plant's roots a loss of turgor occurs and the stomata close. Guard cells loose water and become flaccid.

WebThus, it has the ability to fix carbon dioxide in reduced carbon dioxide conditions, such as when the stomata on the leaves are only partially open. As a consequence, at similar rates of photosynthesis, C 4 plants lose less water when compared with C 3 plants. This explains why C 4 plants are favoured in dry and warm environments.
