Plant cells
In addition to the sub-cellular structures found in an animal cell, a typical plant cell also has:
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.
