There are three processes you need to know of:
Diffusion, Osmosis and Active Transport.
Liquids (such as water) move via osmosis.
Osmosis is literally the movement of particles across a partially permeable membrane from an area of high conc to an area of low conc.
CO2 would move via either diffusion or active transport.
Diffusion is the movement of particles across the concentration gradient (i.e from high conc to low conc)
Active transport is the movement of particles against the conc gradient (i.e from low conc to high conc)
