Is cyanobacteria a prokaryote or eukaryote?
Cyanobacteria are prokaryotes. They lack a membrane-bound nucleus and other organelles commonly found in eukaryotic cells.
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.
What membrane bound organelle associated with photosynthesis is absent in cyanobacteria?
Cyanobacteria lack chloroplasts, which are membrane-bound organelles associated with photosynthesis found in eukaryotic cells, such as plants and algae. Instead, cyanobacteria perform photosynthesis using thylakoid membranes that are integrated into their cell membrane. These thylakoids contain chlorophyll and other pigments necessary for capturing light energy, allowing cyanobacteria to conduct photosynthesis without the need for chloroplasts.
What organelle present in alga and plant cell is lacking in cyanobacteria cells?
Cyanobacteria lack chloroplasts, which are organelles found in alga and plant cells responsible for photosynthesis. Instead, cyanobacteria perform photosynthesis using thylakoid membranes within their cytoplasm. This fundamental difference highlights the distinction between eukaryotic organisms, like plants and algae, which possess membrane-bound organelles, and prokaryotic organisms like cyanobacteria.
Do prokaryotes lack mitochondria?
No they do not have.They do not have any membrane bound organell.

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.
Is monera eukaryotic?
No, Monera is not eukaryotic. It is a biological kingdom that includes prokaryotic organisms like bacteria and cyanobacteria, which lack a true nucleus and membrane-bound organelles. Eukaryotic organisms, on the other hand, have a true nucleus and membrane-bound organelles.
Do prokaryotes lack mitochondria?
No they do not have.They do not have any membrane bound organell.
Is cyanobacteria Eukaryotic or Prokaryotic?
Prokaryote
Do bacteria lack chlorophyll?
Yes, bacteria generally lack chlorophyll. In cyanobacteria, however, chlorophyll is found.
Where in cyanobacteria does photosynthesis occur?
Photosynthesis in cyanobacteria occurs in specialized structures called thylakoids, which are membrane-bound compartments within the cell where the photosynthetic reactions take place.
Do prokaryotes lack membrane-bound organelles?
Yes, prokaryotes lack membrane-bound organelles.
Are cyanobacterium prokaryotic or eukaryotic?
The kingdom Plantae falls under the domain Eukaryota.
Microscopic single celled organism that has no defined memebrane bound nucleus would fit into which 2 kingdoms?
The microscopic single-celled organism without a defined membrane-bound nucleus would fit into the kingdoms Bacteria and Archaea. These organisms are known as prokaryotes and lack a true nucleus, making them distinct from eukaryotic organisms found in the kingdom Protista, Fungi, Plantae, and Animalia.
