4. Plant cell While observing cork through his microscope, Hooke saw tiny boxlike cavities, which he illustrated and described as cells.  He had discovered plant cells!  Hooke's discovery led to the understanding of cells as the smallest units of life—the foundation of cell theory.

5. Animal cells In the nineteenth century, biologists began taking a closer look at both animal and plant tissues, perfecting cell theory. Scientists could readily tell that plants were completely made up of cells due to their cell wall. However, this was not so obvious for animal cells, which lack a cell wall. Many scientists believed that animals were made of “globules.”
