a microscopic chemical lab that lasts ten days before quitting and being reborn.
means One of the tiny sensory clusters on your tongue and mouth that detect the five basic tastes — sweet, salty, sour, bitter, and savory — and report them to your brain.
from A plain English compound of "taste" and "bud." "Taste" came through Old French "taster" (to touch, try, sample), from a Latin root meaning to feel or handle — a reminder that tasting was once cousin to touching. "Bud," the little swelling on a plant ready to bloom, is native English of uncertain deeper origin; here it describes the shape, since each one looks like a tiny bulb nestled in the tongue's surface. So a "tastebud" is literally a small budding organ for sampling the world.
