Solution
The correct option is D Mycoplasma
Dinoflagellates are photosynthetic eukaryotic organisms and have a cell wall made of cellulose.
Actinomycetes are bacteria with a cell wall made of muramic acid.
Cyanobacteria have a gelatinous cell wall.
Mycoplasmas are pathogenic bacteria that have no cell walls. Hence they are resistant to antibiotics that target cell wall synthesis mechanisms in bacteria.
