4 - there is a 2:1 ratio for surface area to volume of a cell.

It's the plasma membrane. This is because it acts like a gate regulating what can enter and leave the cell. If the plasma membrane did not exist the cell would die because it might take in something that could kill it.
Yes. Mitosis starts off as a single cell then the cell membrane disinegrates, the DNA divides and the cell membrane grows back on. And it eventually doubles and it repeats the process over and over.
Cell membrane
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
the cell membrane is as flexible barrier outside of the cell.

The outer boundary of a general animal cell is the cell membrane.
There are multiple membranes in a cell. Two of them are the cell membrane and the nucleur membrane.

the cell membrane is the outer part of the cell wall.
