The importance of homeostasis

Cells depend on the body environment to live and function. Homeostasis keeps the body environment under control and keeps the conditions right for cells to live and function. Without the right body conditions, certain processes (eg osmosis) and proteins (eg enzymes) will not function properly.

Why is homeostasis important for cells?

Living cells depend on the movement of chemicals around the body. Chemicals such as oxygen, carbon dioxide and dissolved food need to be transported into and out of cells. This is done by the processes of diffusion and osmosis, and these processes depend on the body's water and salt balance, which are maintained by homeostasis.

Cells depend on enzymes to speed up the many chemical reactions that keep the cell alive and make it do its job. These enzymes work best at particular temperatures, and so again homeostasis is vital to cells as it maintains a constant body temperature.
