Division Cyanophyta (which is in Kingd om Monera) contains the cyanobacteria, which are one-celled or colonial prokaryotes that contain chlorophyll (but not chloroplasts, which contain the chlorophyll in true plants). Cyanobacteria are autotrophs (create their own energy via photosynthesis) and reproduce by fission (splitting in two). There are over 7,500 species of cyanobacteria and they are found in many environments: damp soil and rocks, fresh water, and salt water.
