Q
What are does the internal membranes of eukaryotic cells do
A
Increases the total area of the membrane
2
Q
Why is the plasma membrane of eukaryotic cells too small to carry out all the vital functions needed by the membrane
A
Because of their size, eukaryotes have a
relatively small surface area to volume ratio.

Q
What does the ER form
A
The endoplasmic reticulum (ER) forms a network of membrane tubules continuous with the nuclear membrane
4

A
A series of flattened membrane discs
