Plant Cells
Biology: AQA GCSE Higher, topic 1.1.11
Plant Cells
As well as the sub-cellular structures that animal cells have, a typical plant cell has a few more:
Permanent vacuole
- A permanent vacuole is a fluid-filled sac that stores water.
- It is enclosed in a membrane (a wall that substances can pass through).
- It can make up as much as 90% of a plant cell’s volume.
Chloroplasts
- Chloroplasts contain chlorophyll, which is needed for the process of photosynthesis.
Cell wall
- The cell wall surrounds the cell and is made of cellulose.
- The cell wall increases the structural strength of the cell.

What sub-cellular structures do plant cells have, that animal cells do not have?
What does the membrane around a plant cell's permanent vacuole allow to happen?
What effect does the cellulose in a plant cell wall have on the cell?
