According to sugar concentration theory,during daytime ,the guard cells begin photosynthesis and the sugar produced during the process increases the osmotic pressure which draws in water from the adjoining cells due to endosmosis.
Guard cells become turgid and their thin wall bluges outwards. Diffusion of gases in and out take place. During night time, the roots sense the shortage of water, therefore gradual loss of water takes place. This is sugar concentration theory.
