Question: What are cells actually made of?

Callum Johnston answered on 23 Nov 2012:

There are a few basic building blocks that actually make up a cell. The membrane which separates one cell from the next is made mostly of fats! Then inside the cell the nucleus contains DNA, this is like an instruction book of how to build all the machines the cell needs to do its jobs, like make energy, move, grow and replicate. These machines are all made of proteins and that is what makes up most of the inside of the cell!
