Biology is a branch of science that studies organisms (living things) and their changes. It includes the study of cells, plants, animals and the human body. It studies all forms of life no matter where they exist, from the largest to the smallest.

Useful words

Here are some words you may come across when learning about biology:

Organisms: All living things are called organisms. Plants, animals, humans and even germs are all organisms.

Cells: All living things are made up of cells. Some living things like bacteria are made up of just one cell. Animals and plants are made up of millions of cells.

Genes: Genes determine how living things grow and function. They pass down characteristics from parents to children like hair colour and eye colour.

Life cycle: The stages that all living things go through from the beginning of life until the end of life.

Food chain: A food chain shows how living things get food from other living things. For example cows eat grass and humans eat cows. Grass is lower in the food chain than cows and cows are lower than humans.

Body systems: Are the organs and systems that keep the body functioning. They include the lungs in the respiratory system, the heart in the circulatory system and the stomach in the digestive system.
