Level Of Organisation
Muhtasari
A single heart cell cannot pump blood around the body on its own. Thousands of cardiac muscle cells, working together as a tissue, contract in rhythm. Those tissues combine into the heart organ, which forms part of the circulatory system. This layered arrangement, from the smallest organelle to the largest organ system, is how complex organisms achieve things no single cell could manage alone.
In this lesson you will learn the five levels of organisation in multicellular organisms: organelles, cells, tissues, organs and organ systems. You will explore examples from both animals and plants and practise identifying each level in diagrams.
Malengo
- Describe the levels of organisation in organisms: organelles, cells, tissues, organs and systems
