Answer: Absorption of water from the soil by root hair cells of plants, thereby increasing water volume in plant cells.
Movement of water from the root hair cells across the cells of the cortex to xylem structures.
Makes plant cells turgid hence firm and rigid, giving support to seedlings and herbaceous plants.
During the day photosynthesis takes place in the Chloroplasts of the guard cells, glucose is formed, and more water is drawn from the neighboring epidermal cells by osmosis and becomes turgid hence opening the stomata.
Reabsorption of water from the kidney tubules into the bloodstream/osmoregulation by the hormones antidiuretic hormone.
