Every living thing on our planet, from plants to animals, is made up of cells. Cells are the building blocks of life, but what are they and how do they work?
- All cells have vital genetic information contained within the nucleus, which sits in cytoplasm.
- In animal cells, cytoplasm also contains protein-producing ribosomes, and mitochondria - which is essential for respiration.
- In plant cells, salts, proteins and pigments are contained within a permanent vacuole.
- Chloroplasts within cells enable plants to harness light energy through photosynthesis.
