What's the difference between an animal cell, a plant cell and a bacterial cell?

An animal cell is eukaryotic and has

·      A nucleus containing the DNA

·      Mitochondria that produce the cell’s energy currency – ATP

·      ER where proteins are made

·      The golgi apparatus where molecules are sorted and packaged for transportation

·      Lysosomes that break down unwanted molecules

·      A cell membrane that lets things in and out

A plant cell is also eukaryotic and has everything an animal cell’s got as well as

·      A vacuole- a space for storing sugars

·      A cell wall to provide structure and to protect the cell

·      Chloroplasts that photosynthesise and transform light energy into chemical energy in the form of sugars (like glucose)

A bacterial cell is prokaryotic and has

·      No nucleus (instead the DNA is in the middle of the DNA as a nucleoid, with other small plasmids around it)

·      A cell wall to protect the cell and stop it shrinking or bursting

·      Flagella that rotate and propel the bacterium along

·      Ribosomes to make proteins
