Every living thing is made up of cells. Many cells differ in size or shape and have different functions
of four regions, the cell body, dendrites, axons and presynaptic terminal. The cell body (soma) contains
The cell membrane consists of eight distinctive parts that each have their own unique structure and function
In an animal cell, plasma membrane is the border surrounding the cell that allows the passage of enough

A eukaryotic cell not only has a plasma membrane as its external boundary, but it also has a variety
and functioning of cell membranes, and explain how they compare to the membranes relating to a specific

A membrane is the cell’s gatekeeper. This phospholipid bilayer says what molecules can move in or out
