Which group of organisms is capable of performing photosynthesis?

• A. Animals and protozoa
• B. Plants, algae, and cyanobacteria
• C. Fungi and most bacteria
• D. Archaea that use methane as an energy source

Answer: (B)

Verified step by step guidance

1. Understand that photosynthesis is the process by which certain organisms convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.
2. Recall that photosynthesis primarily occurs in organisms that contain chlorophyll or similar pigments capable of capturing light energy.
3. Identify that plants and algae are well-known photosynthetic organisms because they contain chloroplasts with chlorophyll.
4. Recognize that cyanobacteria, a group of bacteria, also perform photosynthesis using pigments similar to those in plants and algae.
5. Conclude that animals, protozoa, fungi, most bacteria, and archaea that use methane as an energy source do not perform photosynthesis, so the correct group is plants, algae, and cyanobacteria.
