Some cyanobacteria produce hormocysts, which are multicellular structures having a thick and massive sheath. Phylum: Cyanobacteria This phylum includes photoautotrophic bacteria that utilize photosynthesis but lack chloroplasts. They produce acidic chemicals for counteracting alkalinity of the soil and they supply nitrogen compounds which are generally deficient in these soils. The phycobiliproteins are phycocyanin (PC), allophycocyanin (AP), allophycocyanin B (APB), and phycoerythrin, and. So far as the sexual reproduction in its true sense is concerned, it is absent in them and the requirements of sexuality are considered to be met by some alternative pathways referred to as parasexual-pathways. Cyanobacteria of subsection I (formerly Chroococcales) and II (Pleurocapsales) are unicellular coccoids. The bacteria also falls under Kingdom Monera and Division Eubacteria. They do not have true roots, stems, and leaves as embryophytes do. 6. These short pieces of filaments are called hormogonia. Oscillatoria is a genus of filamentous cyanobacteria. Meaning and Characters of Cyanobacteria: The cyanobacteria (the earlier blue-green algae), or the blue-green bacteria, represent a group of photosynthetic, mostly photolysis-mediated oxygen-evolving monerans (prokaryotes). Privacy Policy3.
