| principal feature of many tropical marine communities is the prevalence of algal-cnidarian symbioses. This study addresses the mechanisms by which glycerol and glucose enter freshly isolated zooxanthellae (FIZ), Symbiodinium microadriaticum (Freudenthal), of the mangrove jellyfish, Cassiopea xamachana (Bigelow), and the specific sites of host factor interaction. Glucose entry into FIZ is accomplished by a Na;Inhibition of glucose uptake by a low molecular weight fraction of host homogenates (mol. wt. |
