Photosynthesis occurs in which types of organisms?

• A. Only Eukaryotes
• B. Prokaryotic and Eukaryotic organisms
• C. Only Plants
• D. Only Algae

Answer: (B)

Photosynthesis is a process that appears in organisms across different cellular setups, not just in one group. In prokaryotes, certain bacteria have specialized photosynthetic membranes and pigments that capture light and convert carbon dioxide into sugars. In eukaryotes, chloroplasts carry out the same chemistry in plants, algae, and some protists. Because both prokaryotic and eukaryotic organisms can perform photosynthesis, the correct idea is that it occurs in prokaryotic and eukaryotic organisms.
