blue-green algae, blue-green bacteria, and Cyanophyta
Blue-green algae
The organism you are referring to is called a lichen. Lichens are a symbiotic relationship between a fungus and either green algae or cyanobacteria. The fungus provides structure and protection, while the algae or cyanobacteria provide energy through photosynthesis.
Stromalitic cyanobacteria belong to the kingdom Bacteria.
Cyanobacteria were the first organisms to perform oxygenic photosynthesis, a process that uses sunlight to produce oxygen as a byproduct. This ability ultimately led to the increase of oxygen in the Earth's atmosphere, paving the way for the development of aerobic life forms.
Phytoplankton is a diverse group of microorganisms, so it includes many different genera and species. Some common genera of phytoplankton include diatoms (Bacillariophyta), dinoflagellates (Dinophyta), and cyanobacteria (Cyanophyta/ Cyanobacteria). Each of these groups contains numerous species.
It is believed that cyanobacteria, also known as blue-green algae, evolved into the eukaryote chloroplast through a process called endosymbiosis. This process involved a cyanobacterium being engulfed by a eukaryotic cell and forming a symbiotic relationship, eventually leading to the development of the chloroplast organelle found in plant and algal cells.
cyanobacteria
It's called Cyanobacteria
Cyanobacteria, also called blue-green algae, are bacteria that photosynthesize but do not have chloroplasts.
cyanobacteria contains a green pigment chlorophyll
cyanobacteria
Some bacteria, but not all bacteria, have chlorophyll.
"Bacteria" refers to a whole domain of organisms, which is a classificational level above kingdom. The domain is called "Bacteria", and it contains several kingdoms of bacteria. Cyanobacteria are their own kingdom, generally called "Cyanobacteria" which is part of Archaebacteria.
heterocysts
cyanobacteria
Cyanobacteria is the phylum of bacteria. Often called blue-green algae, it belongs to the bacteria domain and the eubacteria kingdom.
both! some species are unicellular some are multicellular
The cyanobacteria is a consumer
