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:
“The host is rushing ‘twixt night and day,
And where is there hope or deed as fair?
Caoilte tossing his burning hair,
And Niamh calling Away, come away.”
—William Butler Yeats (1865–1939)
