The rate of diffusion depends on... | Temperature, size of the molecules, type of molecules diffusing and the concentration of the molecules is the same on both sides of the membrane |
Osmosis... | the diffusion of water across a semi-permeable membrane |
Water moves from areas of low solute... | to areas of high solute |
Water molecules will cross membranes until the concentrations of water... | and solutes is equal on both sides of the membrane called equilibrium |
At equilibrium, molecules continue to move across membranes... | evenly so there is no net movement |
Hypertonic Solution solute concentration... | outside the cell is higher |
Hypotonic Solution solute concentration greater... | inside the cell |
Isotonic Solution concentration of solutes... | same inside and outside the cell |
The cell of animals on land are... | usually in isotonic environment |
Freshwater organisms live in hypotonic environments so water... | constantly moves into their cells |
Unicellular freshwater organisms... | use energy to pump out excess water by contractile vacuoles |
Plant cell walls prevent plant cells from... | bursting in hypotonic environments |
Some marine organisms can... | pump out excess salt |
