You are told that the cells on a microscope slide are plant, animal, or bacterial. You look at them through a microscope and see cell walls and membrane-bound organelles. How should these cells be classified?

• plant cells

• animal cells

• They could be plant cells or bacterial cells.

• They could be plant cells, animal cells or bacterial cells.
