Algae are which type of organisms?

• A. Plantlike eukaryotes that are photosynthetic
• B. Non-photosynthetic bacteria
• C. Parasitic worms
• D. Acellular particles

Answer: (A)

Algae are plantlike eukaryotes that are photosynthetic. They have a nucleus and organelles, including chloroplasts, which harness light energy to convert carbon dioxide into sugars. They range from single-celled organisms to large multicellular seaweeds and typically inhabit watery environments, forming the base of many ecosystems and contributing significantly to oxygen production. This distinguishes them from non-photosynthetic bacteria (which are prokaryotes), parasitic worms (multicellular animals), and acellular particles like viruses. While some bacteria are photosynthetic, those organisms are not algae because they are not eukaryotic.
