Nostoc and Anabaena are both genera of cyanobacteria. While they share similar characteristics, such as being photosynthetic and capable of nitrogen fixation, they differ in their morphology. Nostoc typically forms gelatinous, colonial masses, while Anabaena forms filamentous chains of cells. Both organisms can thrive in moist environments and play important ecological roles, but they may also produce toxins under certain conditions.
