Host (biology)
In biology, a host is an organism that harbors a parasite, or a mutual or commensal symbiont, typically providing nourishment and shelter. In botany, a host plant is one that supplies food resources and substrate for certain insects or other fauna. Examples of such interactions include a cell being host to a virus, a legume plant hosting helpful nitrogen-fixing bacteria, and animals as hosts to parasitic worms, e.g. nematodes.

Famous quotes containing the word host:
“Carlyle’s works, it is true, have not the stereotyped success which we call classic. They are a rich but inexpensive entertainment, at which we are not concerned lest the host has strained or impoverished himself to feed his guests. It is not the most lasting word, nor the loftiest wisdom, but rather the word which comes last.”
—Henry David Thoreau (1817–1862)
