A cell being observed under a microscope is seen to possess a cell wall, plasma membrane, ribosomes and chromosome material that are not found in a nucleus. Based on this, it could be

  1. a cell from a cactus.

  2. a cell from a paramecium.

  3. a cell from a bacterium.

  4. a cell from a mushroom.

  5. a cell from a fish.



The nucleolus produces ribosomal RNA (rRNA) which will be sent out of the nucleus into the cytoplasm.
