Other forms: zoospores
In biology, a zoospore is a tiny, seed-like cell that propels itself using a long appendage called a flagellum. Some types of bacteria and fungi have zoospores, whose mobility helps them reproduce more efficiently.
For some organisms, like moss, mushrooms, and ferns, tiny spores are the way they reproduce. A zoospore is simply a type of spore that can move around on its own, using its whip-like tail as a propeller. If you take a biology class, you might learn about protozoans and fungi that use zoospores to propagate themselves. This word is formed by adding the prefix zoo-, "animal or living being," to spore, from the Greek spora, or "seed."
