Facilitated diffusion
Endocytosis
Selective permeability
Exocytosis
1. Equal solute concentrations in two solutions.
2. Difference in the concentration of a substance from one
location to another.
3. Protein that detects a signal molecule and performs an action in response.
4. Molecule that forms a double-layered cell membrane.
5. Movement of molecules from a region of high concentration to a region
of low concentration.
6. Solution that has a higher solute concentration compared to another solution.
7. Movement of molecules across a membrane from low to high
concentration; requires energy.
8. Release of substances out of a cell by the fusion of a vesicle with the membrane.
9. Solution that has a lower solute concentration compared to another solution.
10. Diffusion of water molecules across a membrane from high water
concentration to low water concentration.
11. Diffusion of molecules assisted by protein channels that pierce a cell
membrane.
12. Used by cells to take in large materials or liquids, the cell membrane
folds in and forms a vesicle.
isotonic
13. Allowing some substances, but not others, to cross the membrane.
14. Movement of molecules across the cell membrane without energy
input from the cell (high to low concentration).
15. Model that describes the arrangement and movement of the molecules
(lipids, proteins, cholesterol) that make up a cell membrane.
Selective permeability
Concentration gradient
receptor
phospholipid
diffusion

osmosis
Facilitated diffusion
endocytosis
Passive transport
Fluid mosaic model
16. Used by cells to take in large solid particle, the cell membrane “grows”
out around the particle.
phagocytosis
Directions: Label the diagram with the following terms: Phospholipid, hydrophobic region, hydrophilic region, integral
protein, cholesterol
