Solution:

Organelles are specific structures which may be membrane bound found in eukaryotic cell having a specific function viz. Golgi body, and not found in prokaryotic cell.
All the prokaryotes are known to have a cell wall covering over the plasma membrane except mycoplasma, now commonly known as PPLO (Pleuro Pneumonia Like Organisms).
Prokaryotes do not have organelles like eukaryotes but they have structures called mesosome which is formed by the infolding of the cell membrane participating in different activities of the cell. Flagella are long whip-like extensions protruding from the cell membrane through the cell wall of bacteria that helps in their motility. Cilia are a small extension of cell membrane commonly observed in eukaryotes helping in locomotion and capturing substances.
