Light micrograph (polarized light) of Anabaena sp. algae. Anabaena is a genus of filamentous cyanobacteria and are known for nitrogen-fixing abilities. They are one of four genera of cyanobacteria that produce neurotoxins, which are harmful to local wildlife, as well as farm animals and pets. Anabaena is capable to differentiate specialized cells, the heterocysts (round red/green cell in the photograph) to survive under different stress conditions. Under nitrogen limited condition, heterocysts provide the filament with nitrogen by fixing nitrogen. Magnification: x275 when printed at 10 centimetres wide at its longest edge. | |
