Cyanobacteria (blue-green algae) are photosynthetic microorganisms frequently used as model organisms in cell biology textbooks.
What type of cell is a cyanobacterium?
Correct Answer
A prokaryotic cell
Explanation
The cyanobacterium (blue-green alga or blue-green bacterium) is a prokaryotic cell. It lacks a membrane-bound nucleus and membrane-bound organelles. Cyanobacteria are important because they are capable of photosynthesis - they contain photosynthetic lamellae studded with phycobilisomes - and are believed to have been among the earliest oxygen-producing organisms on Earth.
