Question

along with plants and algae, in which organisms can photosynthesis occur?
○ some bacteria
○ all fungi
○ some animals
○ all protists

Explanation:

• Some bacteria: Certain bacteria like cyanobacteria (blue - green algae) can perform photosynthesis. They have pigments (e.g., chlorophyll - like pigments) and the necessary biochemical pathways to convert light energy into chemical energy.
• All fungi: Fungi are heterotrophic. They obtain nutrients by absorbing organic matter from their environment. They lack the pigments and mechanisms for photosynthesis.
• Some animals: While there are some animals that have symbiotic relationships with photosynthetic organisms (e.g., some corals have symbiotic algae), animals themselves do not have the cellular machinery (like chloroplasts with the full set of photosynthetic pigments and enzymes in a way that can independently carry out the full process of photosynthesis from start to finish) to perform photosynthesis on their own.
• All protists: Protists are a diverse group. Some protists (e.g., algae which are a type of protist) can photosynthesize, but there are also heterotrophic protists (e.g., amoebas) that cannot.

Answer:

some bacteria
