许多腔肠动物,如珊瑚、水螅、体内都生活有绿藻。生物学家们正在逐渐探明这些共生体是如何分享营养物质的。G.索林顿及在研究共生、细胞起源和生命起源方面的著名科学家L.马吉利斯现已证明:带有放射性标记的氨基酸和核苷酸是从绿水螅(Hydra uiridis)转移到其共生藻中去的。水螅是一种生活在洁净的淡水溪流和湖中的常见动物。其共生藻(小球藻属)生活于消化道内层的细胞
Many coelenterates, such as coral, water chinense, are living with green algae in the body. Biologists are gradually figuring out how these symbionts share nutrients. G. Thorinton and L. Markis, a well-known scientist who studies symbionts, cellular origins, and the origins of life, have now shown that radioactively labeled amino acids and nucleotides are transferred from Hydra uiridis to their symbiosis Go in the algae. Minamata is a common animal living in clean freshwater streams and lakes. Its symbiotic algae (Chlorella) live in the inner lining of the digestive tract
