Steele HS Cell Structure and Function Review

What is something that prokaryotic and eukaryotic cells have in common?

• They have a nucleus. 

• They are multi-cellular. 

• They have DNA. 

• They have organelles that are membrane-bound.

What is facilitated diffusion?

• Transport that uses proteins to help move molecules across the membrane. 

• Movements of substances through a membrane. 

• When molecules spread from High to Low concentration on their own. 

• When pressure pushes something through a membrane.
