Question

a student uses a microscope to observe a cell and draws the image shown.
which evidence can the student use to confirm which type of cell is being observed?
a a cell membrane is present, which indicates that it is a eukaryotic cell.
b a firm cell wall is present, which indicates that it is a prokaryotic cell.
c a stage of mitosis is shown, which indicates that it is a eukaryotic cell.
d a step of binary fission is shown, which indicates that it is a prokaryotic cell.

Explanation:

• Option A: Both prokaryotic and eukaryotic cells (except some eukaryotic cells like animal cells have cell membrane, and prokaryotes also have cell membrane), so this can't confirm.
• Option B: Plant cells (eukaryotic) have cell walls, so cell wall presence doesn't mean prokaryotic.
• Option C: Mitosis is a process of eukaryotic cell division (prokaryotes do binary fission). The image shows a stage of mitosis (chromosomes separating), so this indicates eukaryotic.
• Option D: Binary fission is prokaryotic division, but the image shows mitosis - like chromosome movement, not binary fission.

Answer:

C. A stage of mitosis is shown, which indicates that it is a eukaryotic cell.
