You will be able to identify the different parts of a leaf and a plant cell.
Understand the process of photosynthesis

4. The structure of a plant cell
Lets start with the basics…………….
The structure of a plant cell
Cell wall – gives support
Nucleus – controls cell function
LD/SD Students to fill in labels on worksheet
Chloroplasts – where photosynthesis takes place
Vacuole – holds water and gives shape

5. Task
Now draw a fully labelled plant cell from memory (include the functions of the relevant parts).

6. How do plants get the food they need?

Discuss with students
Plants cannot move very much, so how do they get the food that they need?

What is the name of the process by which plants

Discuss with students

8. What is photosynthesis?
