Anabaena cylindrica forms filamentous chains composed of vegetative cells, heterocysts, and akinetes.
Heterocysts are specialized cells in Anabaena cylindrica that provide an anaerobic environment necessary for nitrogen fixation.
It can perform photosynthesis and produce oxygen while fixing atmospheric nitrogen into a form usable by plants.
Anabaena cylindrica has a mutualistic relationship with certain plants, providing them with essential nitrogen compounds.
This cyanobacterium reproduces through fragmentation of filaments and hormogonia formation.
