(1) What is the function of the algae inside corals' tissues? A . To perform photosynthesis. B . To produce energy needed by their host. C . To pump light into shaded areas. D . To build complex skeletal structures. (2) What do algae get in the symbiotic relationship with corals?
Symbiotic transitionalgae-coral triggeredpaleoclimatic eventsThe algae–coral endosymbiosis is a canonical instance of mutualistic interaction, a textbook example of a relationship between two species in which each derives benefits. The dinoflagellate algae accommodate nearly all of the respiratory demands of...
Corals and algae have a mutually beneficial orsymbiotic relationship. Algae, which live protected in coral polyps, make much of the food consumed by a reef. Each sedentary animal that is part of a reef possesses a hard exoskeleton that contributes to its strength and rock-like appearance, but ...
Coral bleaching is a stress condition in reef corals that involves a breakdown of the symbiotic relationship between corals and algae (zooxanthellae). The algae provides food for the coral and also holds the colony together. The bleaching of the coral indicates the absence of the algae and signal...
The algae gets energy from the sun and shares it with the coral internally. The coral builds a rock-like structure, which makes up most of the reef, providing homes and food for many organisms that live there. Coral bleaching is when the symbiotic relationship breaks down. Without the algae...

These results indicate some of the algae, and is considered, together with Fe SOD, fundamental processes needed for successful to be an evolutionarily ancient form of SODs Symbiodinim–coral interaction. Pathways related (Lesser, 2006). CAT is a heme-containing enzyme to nutrient transfer, ...
The latter is microscopic algae that grow within corals and share a symbiotic relationship with the polyp. Zooxanthellae are photosynthetic organisms that require sunlight to live. They produce nutrients they share with the polyp, while the polyp offers protection in exchange. ...
