Plant cells have defined structures and organelles that are unique for these type of cells. The organelles of plant cells include: cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes. One key structure that is able to differentiate between an animal and a plant cell is the cell wall, a wall comprised of polysaccharides cellulose that gives stability and rigidity. Since the scientist identified these cell structures on the electron microscope, the kind of organisms that he found at polar ice cap was a plant.
This invention helped them to discover a basic similarity among organisms.
