Cell transport notes
Take Cornell notes in your notebook

Cell membranes and transport
• L.T: • I can identify the structure of a cell membrane. • I can predict movement of substances through the cell
membrane. • I can define diffusion and osmosis.
• Notes = pre lab: – Take notes on the following slides for your pre-lab– No pre-lab…no lab!
– Notebook check off when done- 10 pts

Osmosis and Diffusion:• Osmosis: the movement of water through a
membrane• Diffusion: the movement of any substance
through a membrane– Particles ALWAYS move from high to low
concentration

Solutions:• Hypertonic solution: a solution with MANY particles• Hypotonic solution: a solution with FEWER particles• Isotonic solution: a solution with the SAME number of
particles on each side.

Movement of Particles:
• Selectively permeable membrane: a membrane (like the cell) where some things can cross and some things cannot.
– Particles ALWAYS move DOWN the concentration gradient (from high concentration to low)
• Practice problems wksht:• Try to figure out the problems. • Put these in your notebook as part of your pre-lab
