The image is an electron micrograph of a typical eukaryotic cell.

What can be concluded about the eukaryotic cell from the electron micrograph?

• It is an animal cell because it contains a permanent vacuole.

• It is a plant cell because it contains many lysosomes.

• It is an animal cell because it does not have a cell wall.

• It is a plant cell because it contains many chloroplasts.
