Cytotoxic edema allows cells to
increase volume to the point of rupture, damaging neighboring cells and it causes
ischemia to build up lactic acid due to anaerobic metabolism.
Cytotoxic cerebral oedema is a
type of cerebral oedema, commonly seen in cerebral ischaemia, in which
extracellular water passes into cells, resulting in their swelling. Ischemia
causes the insufficient removal of anaerobic metabolic end products, producing
extracellular acidosis. If the level of the blood flow is reduced,cellular edema can cause the cell membrane to rupture thereby allowing the outflow of
intracellular contents into the surrounding extracellular fluid and this can lead
to the damage of neighboring cells.
During a drought, there is less water available for the plants. There is less runoff and less infiltration. During a drought, less water is returned to the atmosphere by the plants through transpiration, and there is a decrease in the plants' rate of photosynthesis.
