Which statement best describes prokaryote characteristics?

Which statement best describes prokaryote characteristics?

• A. Lacking a cell wall
• B. Cell wall; some are photosynthetic; single chromosome
• C. Mitochondria present in all cells
• D. Multicellular only

Answer: (B)

Prokaryotes typically have a cell wall that provides structure and protection, and among them are photosynthetic groups like cyanobacteria. They also usually carry a single circular chromosome located in the nucleoid region, not enclosed by a nucleus. They lack membrane-bound organelles such as mitochondria, and most prokaryotes are unicellular rather than multicellular. So the description that highlights a cell wall, the possibility of photosynthesis, and a single chromosome best fits prokaryotic characteristics.
