Although not [[plant]]s and therefore incapable of [[photosynthesis]] themselves, many sea anemones form an important facultative symbiotic relationship with certain [[cell (biology)|single-celled]] green [[algae]] species which reside in the animals' gastrodermal cells. These algae may be either [[zooxanthella]]e, [[zoochlorella]]e, or both. The sea anemone benefits from the products of the algae's photosynthesis, namely [[oxygen]] and food in the form of [[glycerol]], [[glucose]], and [[alanine]]; the algae in turn are assured a reliable exposure to sunlight and protection from micro-feeders, which the anemones actively maintain. The algae also benefit by being protected due to the presence of stinging cells called nematocysts, reducing the likelihood of being eaten by herbivores. Most species inhabit tropical reefs, although there are species adapted to relatively cold waters, intertidal reefs, and sand/kelp environments.
