Membrane, This is a thin, flexible skin that surrounds the cell. It acts as a gatekeeper, controlling what comes in and what goes out.
These are tiny machines that build proteins. Proteins are necessary for almost everything a cell does. Ribosomes are found in every single type of cell, from simple bacteria to complex humans.
