Describe ways a lack of water could affect cell functions?
ladessa [460]

The way a lack of water could affect cell functions is that cell membranes would lack structure.

Osmosis causes water to flow from the cell into the surrounding liquid. This causes the protoplasm all the material inside the cell, to shrink from the cell wall. Excessive water loss leading to cell wall breakdown can lead to cell death. Water is an important part of the protoplasm of living cells as it is directly involved in myriad biochemical reactions such as photosynthesis and respiration.

Without them, cells cannot move waste and byproducts absorb nutrients, carry out intracellular transport functions or send signals. Regulates body temperature. Moisten eye nose and mouth tissues. Protects body organs and tissues. Carry nutrients and oxygen to cells. Plasmolysis is a situation in which cells lose water in hypertonic solutions. the plant cells lose water causing them to shrink or shrink removing the cell cytoplasm from the cell wall.
