happened to the phospholipid bilayer, oxygen, glucose (food), carbon dioxide (waste product!), and water.

ACTIVE TRANSPORT• EXIT SLIP - Describe what

happened to the phospholipid bilayer, ATP, sodium, potassium, sugar.

11/28/12 Wednesday

• Entry task

• How do you think the cell uses passive and active transport to maintain homeostasis?

• Introduce concept mapping…

Cell Membrane Concept Map• Concept Maps:

– Big ideas towards to top and details down lower.

– Each line explains the relationship between the words.

• Work in partners to arrange the following words in a concept map.

• Please include a diagram to add more information to your map.

– Cell membrane– Homeostasis– Phospholipid bilayer– Polar heads– Non-polar tails– Glucose– Oxygen– Carbon Dioxide– ATP– Mitochondria– Passive Transport– Diffusion– Active Transport– Active Transport Pump– Endocytosis– Exocytosis
