5
Why is the phospholipid bilayer special?
It does not let water through
It doesn't let any molecules through
It likes water
It has hydrophobic and hydrophilic components
6
A semi-permeable membrane:
Acts a a barrier preventing flow of material
Only lets water through
Let's all molecules through
Allows some molecules to go through
7
Osmosis is passive
False
True
8
This diagram depicts:
Active transport
Bulk transport: Exocytosis

Passive transport
9
What is one of the main differences between plant and animal cells?
Animal cells have a strong outer membrane (cell wall)
Chloroplasts are present in plant cells but not in animal cells
There are no differences between plant and animal cells
Plant cells have a small vacuole compared to animal cells
10
Simple diffusion across a membrane requires the assistance of a protein
False
True
11
What is a key benefit of cells being small?
Increases mobility
Conservation of energy
