Key Stage 3

Meaning

A picture of a single animal cell at x1000 magnification.

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

Euglena.png
The cells in an onion stained blue. Muscle cells stained pink. A single celled organism called a Euglena that is green because of the chlorophyll inside.

4 White blood cells stained purple surrounded by several red blood cells. Several different types of plant cell found in a leaf. Sperm cells stained purple and shown under a microscope.

Key Stage 4

Meaning

A cell is the smallest living part of an organism.

About Cells

Cells can be divided into two main groups Eukaryotic Cells, which contain membrane bound organelles, and Prokaryotic Cells which do not contain membrane bound organelles.
