A scientist looks at a cell. It has a nucleus, mitochondria, ribosomes, a cell membrane, a cell wall and a large vacuole, but no chloroplasts.
What can the scientist conclude?
it must be an animal cell because it has no chloroplasts
it must be a bacterial cell because it has a cell wall
it cannot be a plant cell because plant cells all photosynthesise
it could be a plant cell from a part that receives no light
