Question

You find a population of strange cells in a sample of pond water. You wish to determine first whether they are eukaryotic or prokaryotic. You look for a membrane-enclosed nucleus and don't see one, but sometimes the nucleus is hard to spot without staining. What else could you look for to determine which cell type this is?

Answer 1

Membrane bound cell organelles

Step-by-step explanation:

A prokaryotic cell lacks a membrane defined nucleus and all the membrane-bound organelles. A eukaryotic cell has a membrane-bound nucleus and other membrane-bound organelles such as mitochondria, chloroplasts, endoplasmic reticulum, lysosomes, Golgi apparatus, etc.

To determine if a cell is a prokaryotic or eukaryotic, one can look for the nucleus and the membrane-bound organelles. If the cell has a nucleus and membrane-bound organelles, it is a eukaryotic cell. The absence of these structures makes it a prokaryotic cell.
