Cyanobacteria is a phylum of bacteria that obtain their energy through photosynthesis.

Cyanobacteria
Lichen is the organism made of a fungus and either green algae or cyanobacteria living together in a symbiotic relationship. The fungus provides structure and protection, while the algae or cyanobacteria provide nutrients through photosynthesis.
cyanobacteria
Heterocysts are specialized cells found in cyanobacteria, particularly in filamentous species like Anabaena and Nostoc. These cells are involved in nitrogen fixation, converting atmospheric nitrogen into a form that can be utilized by the organism.
A heterocyst in cyanobacteria is a specialized cell that helps in nitrogen fixation, converting atmospheric nitrogen into a form that can be used by the organism for growth and metabolism.
cyanobacteria releases oxygen as a byproduct into the atmosphere.
Organisms formerly known as blue-green algae are actually cyanobacteria. Cyanobacteria are a type of bacteria that can perform photosynthesis like plants, leading to their previous misclassification as algae.
Probably ancient cyanobacteria.
Prokaryotic organisms have no nucleus. This includes all bacteria, including the archea and cyanobacteria.
Cyanobacteria, also called blue-green algae, are bacteria that photosynthesize but do not have chloroplasts.
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.
