Most reef-building reefs contain photosynthetic algae, called zooxanthellae, that live in their cells. The corals reefs and algae have a mutualistic relationship. The reefs provides the algae with a secured environment and substances they need for photosynthesis. In return, the algae produce oxygen and assist the coral to remove wastes. The relationship between the algae and coral reefs polyp facilitates a tight recycling of nutrients in nutrient-poor exotic waters. As much as 90 percent of the natural material photosynthetically created by the zooxanthellae is moved to the host coral tissue. Along with giving reefs with essential nutrients, zooxanthellae are in charge of the beautiful and one-of-a-kind shades of many hostile corals. Occasionally when corals reefs end up being literally stressed, the polyps remove their algal cells and the colony handles a plain white appearance. If the polyps go for too long without zooxanthellae, coral whitening can lead to the coral's death. Coral reef corals reefs require clear water to ensure that sunshine can reach their algal cells for photosynthesis. Zooxanthellae cells provide corals reefs with coloring. It will most likely die if a coral reefs polyp is without zooxanthellae cells for a lengthy period of time. Coral reefs polyps generate co2 and water as results of cellular respiration. The zooxanthellae cells use carbon dioxide and water to perform photosynthesis. Tiny plant cells called zooxanthellae live within most types of coral reefs polyps. Consequently, the reefs polyps provide the cells with a protected environment and the nutrients they require to execute photosynthesis.
