Cyanobacteria are ubiquitous, finding habitats in most water bodies and in extreme environments such as the polar regions, deserts, brine lakes and hot springs. They have also evolved surprisingly complex collective behaviours that lie at the boundary between single-celled and multicellular life. For example, filamentous cyanobacteria live in long chains of cells that bundle together into larger structures including biofilms, biomats and stromatolites. These large colonie… Webis that trichome is (botany) a hair- or scale-like extension of the epidermis of a plant while filament is (botany) the stalk of a stamen in a flower, supporting the anther.
