Passive transport means the cell does not have to spend energy to move gasses and fluids. the gasses or liquids go from a higher concentration to a place of lower concentration. Think about shaking a can of soda. There's a lot of pressure that builds up in the soda. When you open the soda, all of the pressure escapes to an area of lower pressure outside of the can. This is called diffusion. Osmosis is another form of passive transport. For example, in water osmosis, the water goes from a less salty solution to a more salty solution.
