What is the other name for the plasma membrane?
Cell membrane
What is the function of the plasma membrane?
It regulates what enters and exits the cell.
Why is it important that the plasma membrane regulates what enters and leashes the cell?
Because it helps the cell and the organism maintain a steady internal environment.
What is the key structure of the plasma membrane?
It's made up of proteins and phospholipids.
Is the head of the phospholipid hidrophilic or phobic?
It's hydro Philip because it loves the water.
Is the tail of the phospholipic hydro phylic or phobic?
It's hydro phobic because it has a phobia of water.
