Concepts to know:
Structure of the plasma membrane- label parts
Function of parts of the plasma membrane
Be able to predict which type of molecules can diffuse through the plasma
membrane and which kind need to use a transport protein
Be able to explain the processes of diffusion, facilitated diffusion, osmosis, active
transport, endocytosis, and exocytosis and give examples
Be able to predict the effect of a hypotonic, isotonic or hypertonic solution on a
cell
Be able to discuss how the plasma membrane helps a cell maintain homeostasis
Dialysis tubing lab/demonstration – be able to explain which molecules diffused
through “membrane” and which molecules did not and why.
Egg demonstration – be able to predict what will happen to egg in hypotonic,
isotonic and hypertonic solutions
Ideal cell size activity - Be able to relate surface area and volume ratios to cell
size and rate of diffusion
