This overview explores the concepts of homeostasis, osmosis, facilitated diffusion, passive and active transport. It describes how these transport mechanisms help maintain cellular equilibrium by controlling the movement of substances in and out of cells. Relevant definitions, such as diffusion, isotonic, and turgor pressure, are provided, along with examples of cellular structures like contractile vacuoles and carrier proteins that play crucial roles in these processes. Understanding these concepts is vital for comprehending how organisms maintain stable internal conditions.

Helps an organism maintain homeostasis by controlling what enters or leaves the cell
Causes the concentration of molecules to be the same throughout a space
State that exists whenever molecular concentration is the same throughout a space
When the concentration of solutes inside & outside the cells is equal
Solute concentration that causes water to move into the cell
Prefix that refers to a high solute concentration & low water concentration outside the cell
Facilitated diffusion is another example of this type of transport
Direction across the cell membrane that carrier proteins allow movement
This happens to a carrier molecule when it binds with the molecule it’s moving
Point where molecules continue to move without a concentration gradient
