2.1 Describe the levels of organisation within organisms:
- Organelles, cells, tissues,organs and systems.
Organelles: Highly organised structures of molecules.
- They have a specific function within a cell. Mitochondria is an example, generating energy for our bodies cells.
Cells: Made up of Organelles, described as a functional unit, they are the basis of living things.
Tissues: A collection of similar cells all serving a common function.
Organs: Made up of several kinds of tissues together forming a functioning unit.
Systems: Several organs forming an organ system.
- Like the cardiovascular system is made up of the heart, blood and blood vessels.
