1. LO: I can recap my learning of cells to prepare for Bacc Exam
What is a cell?
Starter: What do you think this photo is of?

2. What is a cell? What is a cell?
A cell is the very smallest unit of living matter.
All living things, including plants and animals, are made up of cells.

3. What is a cell? What is a cell?
There are many different kinds of cells, doing many different jobs in a plant or animal.

4. Animal and Plant Cells
Animal and plant cells

5. Cell Membrane Cell membrane
One part found in all cells is the cell membrane. The cell membrane surrounds the cell and holds the cell together. It controls what chemicals can enter and leave the cell.

6. Nucleus
Nucleus
Another part found in all cells is the nucleus. The nucleus controls the cell. Inside the nucleus is DNA which contains genetic information.

7. Cytoplasm
Cytoplasm
All cells also contain cytoplasm. Cytoplasm is a jelly-like mixture of chemicals where most of the work of the cell takes place

8. Parts of a Plant Cell Plant cell parts
Plant cells may contain some extra parts.

9. Chloroplasts (plant cells)
Chloroplasts which are disc shaped and contain chlorophyll for photosynthesis.

10. Cell wall (plant cells)
A cell wall which is a strong outer layer to support the cell and give it shape.

11. Vacuole Vacuole (plant cells)
A vacuole where the plant cell stores sap (the food that it has made; a mixture of sugars, salts and water).

12. In reality …. More complicated!
Most cells are much more complicated than this!

13. Then grab a whiteboard and come round the front
