Problem:

Question 1: Define simple diffusion, using the words concentration gradient. Give an example.

Question 2: Define osmosis. Define isotonic, hypertonic, and hypotonic solutions and give examples how these 3 types of tonicity effect red blood cells and plant cells using proper terminology (example: red blood cells undergo hemolysis when placed in a hypotonic environment)

Question 3: How does facilitated diffusion differ from simple diffusion across the plasma membrane? Give an example of facilitated diffusion.

Question 4: How does active transport differ from facilitated diffusion? Give an example of active transport.

Question 5: Diagram and define endocytosis and exocytosis.

Question 6: Describe and compare the three methods of endocytosis

Any help would be greatly appreciated!
