protists means: One- or multi-celled organisms, protists can live in wet and moist environments. They may be animal, plant, or fungus like. All of them are eukaryotic, which means that their cells contain a nucleus. Algae are found in plants and protists. Photosynthesis is the process by which algae can produce their own energy using sunlight. They have multiple cells. Other plant-like protists, however, have single celled organisms. Their tails look like flagellums and they have eyespots to sense light. They are similar to animal protists and are known as protozoans. Protozoans have single-celled bodies, but special holes called vacuole. (in Community Dictionary, added by Laney Schultz)
