Here are a few definitions (along with pictures) that I have been discovering along the way:

*fungicide: an agent that kills fungi
"This new fungicide helps prevent disease control for shrubs, flowers and roses."

*flagellum: a thin threadlike attatchments on prokaryotic and eukaryotic cells that are helpful to their mobility.

" Bacteria uses their flagellum to swim around their aqueous environment."

*extremophiles:microorganisms that grow under harsh or extreme environmental conditions such as very high temperatures or low PHs
"Extremophiles are found in a unexpected, even extreme places."
