Nucleolus
Dark-staining, spherical body in the nucleus that produces ribosomal subunits.
RER
Continuous folds of membrane linked with the nuclear envelope Rough surface
SER
Smoother surface, outer section of ER
Golgi body
Can be distinguished from ER as it is not connected to other membrane-bound compartments and has a 'wifi-symbol' appearance
Mitochondria
Relatively large organelles surrounded by double-membrane Smaller than nucleus and chloroplasts but can be seen with a light microscope
Chloroplasts
Larger than mitochondria, contain grana, surrounded by double membrane
