Virus
A virus is an infectious particle containing genetic material inside a protein coat, sometimes with an outer envelope.

What are they, and what does the difference actually look like?
Two things. One honest scale.

A virus is an infectious particle containing genetic material inside a protein coat, sometimes with an outer envelope.
100 nmCharacteristic size
A pollen grain carries the male reproductive cells of a seed-producing plant.
30 µmCharacteristic sizePollen grain has about 300 times the characteristic size of Virus.
A chosen 100 nm viral particle, including the approximate envelope. Viruses vary greatly.
