The plant cell

Plant cells are eukaryotic cells because they have a nucleus. Unlike animals cells, the cell (plasma) membrane of plant cells is surrounded by a tough cellulose cell wall. Plant cells also often have large vacuoles in their cytoplasm. The plant cells that carry out photosynthesis also contain special organelles called chloroplasts.

Both images are sections of plant cells photographed with a transmission electron microscope.

Plant cells

This image shows several cells lying next to each other separated by thick cell walls (note also the nucleus which is about 5 micrometers in diameter). 

 

 

This plant cell has a much thinner cell wall. The cell contains numerous chloroplasts and also not the large vacuole. You should also be able to pick out the nucleus. The cell is about 22 micrometers across at its widest point.
