Cells

Cells are able to function because of the many organelles working together within them. Lets find out what some of these are:

Plasma/Cell Membrane

Description/Structure

Not a solid structure, made of millions of smaller molecules that create a flexible and porous container.

Function

Keeps the pieces inside
