Organelle

• Made up of many organs all working towards the same purpose.

• Component of a cell. Each one has a particular function within the cell.

• A group of cells of the same type working together.

• Smallest living unit of an organism. Made of organelles.

Organism

• Made up of many organs all working towards the same purpose.

• A group of tissues working together to carry out a particular function.

• This is a living thing. It can either be made up of one cell (e.g. bacteria) or many cells (e.g. human)
