Which pair of structures would provide a positive identification of an animal cell under a microscope?

flagellum, lysosome


nucleus, mitochondrion

ribosome, cell wall

chromatin, chloroplast

Answer 1

Step-by-step explanation:

Firstly cell wall and chloroplasts can only be found in plant cells and will not appear in an animal cell.

Flagellum usually appears in many bacteria (microorganism) and only a few animal cells. Most animal cells do not have flagellum.

However animal cells do have a nucleus which contains important genetic material such as DNA and mitochondrion which creates energy for the cell to use for metabolism inside the cell. (Even though most eukaryote cells have these 2 organelles)

Between the 1st and 2nd options, none of them is exactly correct. But nucleus and mitochondria are more widely found in various types of cells (plants, etc.)

I would choose the 1st option as the best answer here because it is more detailed.

Answer 2

flagellum, lysosome: Both of these are found in animal cells, but the real difference is flagellum is ONLY found in animal cells

nucleus, mitochondrion: Both of these are found in Animal cells X

ribosome, cell wall: Cell wall is only in plants X

chromatin, chloroplast: Chloroplast is only found in plant cells X
