Cell Membrane Flashcards
1
Q
What is a cell membrane mostly made of?
A
Proteins and Phospholipids
2
Q
What is a phospholipid made out of?
A
A hydrophilic head and two hydrophobic tails
3
Q
What is the hydrophobic head’s job?
A
To attract water into the cell
4
Q
Does the cell membrane allow anything to go into it?
A
No, it’s semipermeable meaning it only allows small molecules (oxygen or carbon dioxid) to diffuse esaily through the cell.
4
Q

To create a barrier around the cell so that no water leaks out
4
Q
