Answer 1

The correct option is D All of the above

Blue-green algae, mycoplasma and PPLO (Pleuro Pneumonia Like Organisms), all are prokaryotic cells. Prokaryotic cells are characterised by lack of nucleus, instead they have circular DNA floating in the cytoplasm. They also lack membrane bound organelles like endoplasmic reticulum, mitochondria, etc.
