7. The cell labeled A is a bacteria cell
Bacteria cells are similar to eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. The features that distinguish a bactrial cell from other cells or eukaryotic cells include, the circular DNA of the nucleoid, the lack of membrane bound organelles, the cell wall of peptodoglycan, and the presence of flagella.
8. The cell labelled C is a plant cell.
One of the distinguishing feature of plant cell is the cellulose cell wall, other features that distinguishes plant cell from other eukaryotic cells are the presence of chloroplasts, and the intracellular vacuoles. Photosynthesistakes place in the chloroplasts; cell walls allow plants to have a strong, upright structures; and the vacuoles help regulate how cells handle water and storage of other important molecules.
