Key Stage 3
Meaning
A cell is the smallest living part of all living things.
About Cells
- Cells cannot be seen with the naked eye. You need a microscope to see them.
- Every living thing is made of cells but not all cells are the same.
- Cells are made of smaller parts.
- Plant Cells and Animal Cells made of some different parts.
- All cells have cytoplasm and a cell membrane
- Both Animal Cells and Plant Cells have a nucleus and mitochondria.
- Only Plant Cells have chloroplasts, a cell wall and a permanent vacuole
Examples
The cells in an onion. | Muscle cells. | A single celled organism called a Euglena. |
White blood cells surrounded by red blood cells. | Several different types of plant cell found in a leaf. | Sperm cells shown under a microscope. |
