1. Organism

1.1. An organism is made up of all the levels of organization.

1.2. All living things are organisms, such as a human or an animal.

1.3. These have cells that have organelles. They also have tissues that make up organs, which makes an organism. This creating an organism.

2.1. There are 11 major systems in the body.

2.2. When two or more organs come together to perform a function in the body.

2.3. These come together to keep the body alive and running.

3. Organs

3.1. Organs are made of different types of tissue.

3.3. These organs come together to serve a certain purpose.

4. Tissues

4.1. Cells multiply to become tissues.

4.2. Tissues form organs.
