A scientist at the polar ice cap was studying an ice sample from hundreds of meters below the surface. While examining the ice,
the scientist found some cells from many years ago. Using an electron microscope, the scientist identified these cell structures: a cytoskeleton, mitochondrion, nucleus, cell wall, and ribosomes. What kind of organism did the scientist find? a. animal
b. bacteria
c. plant
d. He did not have enough information.
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.
