• Reproduction

• Homeostasis

• Photosynthesis

Identify basic examples of homeostasis.

• Balanced rate of absorbing and using food + oxygen

• Steady regulation of heart rate and body temperature

• Movement of water molecules through a cell membrane

Osmosis is the movement of water molecules through a cell membrane. Why does this help maintain homeostasis?

• All cells need a particular amount of water to live

• Too much or little water can damage or kill a cell.

• Cells don’t need to regulate how much water they have.
