Discuss. CO2 and water move in and out of cells through three main ways
- Diffusion: CO2 moves from where there’s lots of it to where there’s less. It just slips through the cell’s outer layer.
- Osmosis: Water moves to where there are more things dissolved in it. It helps balance stuff inside and outside the cell.
- Facilitated Diffusion: Big or tricky molecules like glucose use special doors in the cell’s outer layer to get in or out.
These processes help cells stay healthy by keeping the right balance of stuff inside and outside them.
