Passive Transport
Diffusion
Osmosis

Plants are constantly absorbing water to keep their cells in a hypotonic environment. Why would they try to maintain this condition?
Hypotonic conditions move water into the cells, increasing turgor pressure.
Hypotonic conditions move water out of the cells, relieving the pressure.
