What is a cell?
Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function.
- Cells are the basic structures of all living organisms.
- Cells provide structure for the body, take in nutrients from food and carry out important functions.
- Cells group together to form tissues, which in turn group together to form organs, such as the heart and brain.
- Our cells contain a number of functional structures called organelles.
- These organelles carry out tasks such as making proteins, processing chemicals and generating energy for the cell.
- The nucleus is based at the centre of the cell and is the ‘control room’ for the cell.
- The genome is found within the nucleus.
