It's easy to tell the difference between an animal cell and a plant cell when you look at it,because a plant cell has a rigid wall around it. This keeps the cell in the right shape. An animal cell looks a bit more like a fried egg - it does not have the wall so is more fluid.A plant cell has a hole in the middle which is filled with sap containing nutrients that the cell needs to grow. An animal cell does not have this.Finally, a plant cell has things called chloroplasts which contain something called chlorophyll, this helps the cell make its energy from light.Both cells share some similar features - they both have a nucleus, which controls the cell. They also both have mitochondria, which provide energy for the cell!
