Question

this chart shows characteristics of four different cells observed under a microscope.
cell | cell wall | chloroplast | mitochondria | ribosome
--- | --- | --- | --- | ---
1 | | | x | x
2 | x | x | x | x
3 | x | | x | x
4 | x | | x | x
which is most likely a prokaryotic cell?
\\(\circ\\) cell 2
\\(\circ\\) cell 3
\\(\circ\\) cell 4
\\(\circ\\) cell 1

Explanation:

Prokaryotic cells lack membrane-bound organelles like mitochondria and chloroplasts but have ribosomes (non-membrane-bound) and may have a cell wall. Cell 3 has a cell wall and ribosomes but no mitochondria or chloroplasts, matching prokaryotic cell characteristics. Cells 1,2,4 have mitochondria (membrane-bound), so they are eukaryotic.

Answer:

Cell 3
