In this review, I will deal principally with the optical morphology of these three types of object, and attempt to outline similarities and essential differences. By this, I mean to include studies of the types of host galaxy, nuclear and galaxy luminosities and colours, interactions with other galaxies, and the general associations with other galaxies. Where relevant, I will refer to morphology at other wavelengths (generally radio), spectroscopy, and UV or X-ray properties. However, I expect these areas to be covered much more fully by other reviews and papers in this volume.
