Do prokaryotes lack mitochondria?
No they do not have.They do not have any membrane bound organell.
Given that prokaryotes lack membrane-bound organelles why do cyanobacteria which are prokaryotes possess membrane-bound thylakoids?
Cyanobacteria were formerly known as blue-green algae which are photosynthetic. Thylakoids in the cyanobacteria are not separate organelles as we see in eukaryotic cell (eg:chloroplast). In fact the chloroplasts of eukaryotic cells were originated in a endosymbiotic event where cyanobacteria was taken up by the cell. Please read about enodsymbiosis.
Does anabaena cells have chlorophyll?
No anabaena cells do not have any organelles so they do not have a nucleus. This is because they can perform photosynthesis in their own cell membrane.
Microscopic single celled organism that has no defined memebrane bound nucleus would fit into which 2 kingdoms?
Archaebacteria and Eubacteria
Do eubacteria have mitochondria?
While eubacteria may lack the organized organelles found in eukaryotic cells, many eubacteria have specialized internal membranes. Cyanobacteria, for example, have membranes that contain chlorophyll and other chemicals required to carry out photosynthesis.

What are the charateristics of monera?
Monera do not have nuclear membrane and they also lack membrane bound cellular organelles. This Monera includes bacteria, cyanobacteria, and mycoplasma. They are unicellular organisms and do not have a certain mode of nutrition.
Microscopic single celled organism that has no defined memebrane bound nucleus would fit into which 2 kingdoms?
Archaebacteria and Eubacteria
Do bacteria lack chlorophyll?
Yes, bacteria generally lack chlorophyll. In cyanobacteria, however, chlorophyll is found.
What eats cyanobacteria?
Pretty much nothing. Your real question has to be, what kills cyanobacteria? The answer to that is lack of nutrition and well-circulated water. Cyanobacteria like nutrients, and moving water prevents them from forming colonies.
Do eubacteria have mitochondria?
While eubacteria may lack the organized organelles found in eukaryotic cells, many eubacteria have specialized internal membranes. Cyanobacteria, for example, have membranes that contain chlorophyll and other chemicals required to carry out photosynthesis.
What is the scientific name for domain bacteria?
Monera - the taxonomic kingdom that comprises the unicellular prokaryotes (bacteria and cyanobacteria). Prokaryotes are single-celled organisms that lack a membrane-bound nucleus and usually lack membrane-bound organelles.
What is prokaryotic?
The word, prokaryotic, refers to cellular organisms (prokaryotes), the cells of which, have no nucleus. So, when reference is made of a prokaryote, generally it is a reference to a species that is ancient, or lower on the evolutionary tree.
Is Cyanobacteria a consumers or producers?
The cyanobacteria is a consumer
What was the first cell to lack a membrane bound nucleus?
prokaryotic cells are the cell that lack nuclear membrane
