Question

24 which of the following is a prokaryotic cell?

Explanation:

Prokaryotic cells lack a true nucleus and membrane - bound organelles. The cell labeled A has a nucleus (the purple - colored structure) and organelles like chloroplasts (the green, oval - shaped structures), which are characteristic of eukaryotic cells (in this case, a plant cell). The cell labeled B lacks a true nucleus (has a nucleoid region instead) and membrane - bound organelles, which are features of prokaryotic cells (in this case, a bacterial cell).

Answer:

B.
