Cell structure GapFill

Eukaryotic cells and prokaryotic cells share some of the same features, including:

In addition to the components listed above, a eukaryotic cell is likely to have several  walledmembrane-boundphotosyntheticendocrine organelles, such as mitochondria, chloroplasts, Golgi apparatus and endoplasmic reticulum, which is categorised as  smooth or roughshiny or dullflexible or inflexiblehard or soft, depending on whether it contains ribosomes, as well as  ciliaa vacuolegraticulesa cytoskeleton in order to move these components around the cell. Prokaryotes may also contain one or more  vacuolesnucleiplasmidsvesicles, a secondary source of genetic material, and  spindlesa plasmidflagellaGolgi vesicles for locomotion (which may also be present in some eukaryotes but are less common).

Microscopes are useful tools for studying cells and their contents. Light microscopes are cheaper and easier to use than electron microscopes, but their  distributionmagnificationresolutioncolour is not as good, so images are not very sharp. Specimens are placed on slides onto the  stagegraticulelaserfocusing knob and viewed using the eyepiece lens.  Wax distortionLaser scanningGraticule divisionDifferential staining can be used to identify various features of the specimens, and their true size can be calculated by dividing the image size by the  graticule scaleprecisionresolutionmagnification. Electron microscopes can achieve much greater magnifications but have several limitations, including the fact that they cannot be used to view  three-dimensionalcolouredhydrophobiclive specimens.
