Which of these animals is photosynthetic?

Explanation

Photosynthesis is a process by which green plants and some other organisms use sunlight, carbon dioxide, and water to produce oxygen and glucose. The question is asking which animal is photosynthetic. Among the options given, the correct answer is option C - Euglena sp. Euglena is a unicellular organism that belongs to the kingdom Protista. It is unique because it can produce its food through photosynthesis like plants and can also feed on other organisms like animals. Euglena contains chloroplasts, which are organelles that are responsible for photosynthesis in plants. These chloroplasts contain a green pigment called chlorophyll, which absorbs light energy used during photosynthesis. Paramecium and Amoeba are also unicellular organisms, but they do not possess chloroplasts and cannot carry out photosynthesis. Hydra is a multicellular organism that belongs to the phylum Cnidaria, and like Paramecium and Amoeba, it cannot carry out photosynthesis. In summary, Euglena sp. is the only photosynthetic animal among the options given. It can carry out photosynthesis due to the presence of chloroplasts with chlorophyll.
