根据第三段中的 Those polyps have a close relationshipwith algae(海藻) called zooxanthellae,who live inside a coral polyp's tissues. Theygive coral its bright appearance.”和第四段中的“Without their colorful companions,the coral polyps become transparent. ”可知zooxanthellae使珊瑚礁颜色鲜艳,故选 B...
In this symbiotic system, the coral polyps provide a protected habitat, carbon dioxide and nutrients needed for photosynthesis to zooxanthellae; in turn, the symbiotic zooxanthellae provide food as products of photosynthesis to coral polyps. The Photosynthesis of zooxanthellae is therefore an important ...
A coral reef consists of many individual polyps functioning together as one unit. The polyps themselves are transparent. Coral reefs get their color from the tiny creatures living inside the polyps: algae called zooxanthellae. Coral and zooxanthellae enjoy a mutually beneficial partnership, known as ...
What are coral polyps? Coral Reefs: Coral reefs are found all over the world, located generally in the subtropics and tropics. Several major reefs are found around the world, particularly the famous Great Barrier Reef. They can usually be found in shallow waters and support thousands of species...

What is the significance of zooxanthellae to corals? Zooxanthellae are symbiotic algae that provide corals with essential nutrients through photosynthesis, crucial for their growth and color. 15 What is coral? Coral refers to marine invertebrates that form colonies of many identical individual polyps, ...
photosynthesis between retained zooxanthellae, which were isolated immediately after stress treatment, and those released from the coral exposed to either 30 or 32°C, while the zooxanthellae population released at 28°C showed significantly lower PSII functioning than those retained in the polyps. The...
In stressful conditions, coral can expel the algae that grow within their polyps and provides them with oxygen, the zooxanthellae. As a result of this action, the coral bleaches and often die. Since coral plays a major role in the ocean’s habitat and for humans, there are many organizatio...
