HAPPY WEDNESDAY 1. Turn in Page 37 (Osmosis Practice Problems) – Write “CORRECTED” on it BIG and CIRCLED if you did

corrections. Everyone TURN IT IN!!!2. On your Bellwork Sheet write “Finish Molecule Transport Foldable (Page 35)”

= water molecule

= oxygen molecule

= ATP/energy

= movement

• Diffusion OR Osmosis OR Facilitated Diffusion OR Active Transport

• Does it use energy?• What’s moving? Water OR Solutes• Is it moving from High to Low OR Low

to High? • Does it move through the

Phospholipid Bilayer OR Protein Channel?
