Any living thing, such as plants, animals, bacteria, or fungi.

A group of similar cells that work together to perform a specific function.

A structure made of tissues that performs a specific job in the body, like the heart or lungs.

A group of organs that work together to carry out a major function, like the digestive system.

The process plants use to make food using sunlight, water, and carbon dioxide.
