Anabaena (ann-a-bean-a) filamentous blue-green alga (cyanobacterium), some cells are different to others. They are referred to as heterocysts, and seem to be specialised to carry out nitrogen fixation. Differential interference contrast. This picture was taken by David Patterson of material from Limulus-ridden sediments at Plum Island (Massachusetts USA) in spring and summer, 2001. Image copyright: D. J.
