[Visitor (111.55.*.*)]answers [Chinese ] | Time :2024-11-30 | Zooxanthellae It is a type of seaweed, a kind of golden yellow intercellular symbiotic bacteria in a variety of marine animals and protozoa, especially corals, such as stony corals and tropical anemones. It is estimated that there are 30,000 zooxanthellae within every mm3 of coral tissue, and they coexist recipronively with polyps. Most zooxanthellae are autotrophs and provide the host with translocation reduction of carbides, such as glucose, glycerol, amino acids and other photosynthetic products. Zooxanthellae can provide up to 90% of coral reefs' energy needs. In return, corals provide zooxanthellae with protection, shelter, nutrients (mainly waste containing nitrogen and phosphorus) and a constant supply of carbon dioxide needed for photosynthesis.By expelling nutrients, light, and excess cells, corals can control the zooxanthellae population to prevent it from overblooming. Zooxanthellae also inhabit other protozoa (e.g. foraminiferans and radiolaria) and some invertebrates... Reef-building corals are very dependent on zooxanthellae, which confines them to growing only in the translucent zone.
