Otherwise, the refraction at the cover slip-air interface causes the light ray to miss the objective and its information is lost. Even with this magnification, you will not be able discern details of cell structure. You will be able to distinguish the shape of the cells, and the cellular arrangement. Prokaryotic cells do not contain a membrane-bound nucleus or any other membrane-bound organelles. Organelles are organized strctures of macromolecules having a specialized function and are suspended in the cytoplasm. The cytoplasmof prokaryotes is enclosed in a plasma membrane (cellular membrane)and is surrounded by a supporting cell wall covered by gelatinous capsule. Flagella (singular, flagellum) and hairlike outgrowths called pili are common in prokaryotes. Within the cytoplasm of prokaryotes are ribosomes (small particles involved in protein synthesis), mesosomes (internal extensions of the plasma membrane), and chromatin bodies (concentrations of DNA). Prokaryotes do not produce sexually, but they have mechnisms for genetic recombination. Bacterial cells () are classified as cocci if they are round , bacilliif they are rod-shaped, and spirillium if they are spiral-shaped. The diagram indicates intracellular structure of a typical prokaryote.
