14. Components of the Plasma Membrane
The plasma membrane is composed of phospholipids.
Permits materials to enter and leave the cell.
Diffusion
Osmosis

15. Diffusion I Regular Diffusion High to low Facilitated Diffusion
Protein
Active Transport
Low to High
ATP

16. Diffusion V Osmosis Osmosis Special type of diffusion
The movement of a liquid solvent from an area of high concentration to an area of low concentration through a semi-permeable membrane.
The membrane does not allow solutes to pass through.

17. Osmosis Hypertonic vs. Hypotonic
Hypertonic Solution
High concentration of solute
Low concentration of solvent
Solvent wants to enter
Hypotonic Solution
Low concentration of solute
High concentration of solvent
Solvent wants to leave
