1. Single Cell and Multicellular organisms

2. Multicellular organisms are organisms that consist of more than one cell. All plants and animals are multicellular.

3. Single Cell organisms or unicellular organisms are organisms that have only one cell. Most cannot be seen with the naked eye.

5. All living things are made of cells
All living things are made of cells. When many cells group together it is called a tissue.

6. Animal cells do not have chloroplast because animals do not need to make their own food. The vacuole is larger in a plant cell because animals are able to find water where plants cannot.
