An important difference between plasma and LCD technology is that an LCD screen doesn't have a coating of phosphor dots (colors are created through the use of filters). That means you'll never have to worry about screen burn-in, which is great news, especially for anyone planning to connect a PC or video game system.
Fungi, singular, fungus, is a group of eukaryotic, non-phototrophic organisms with rigid cell walls, that includes mushrooms, molds and yeasts. This definition has some words in it that probably need definitions of their own.
Yeast are single-celled microorganisms that are classified, along with molds and mushrooms, as members of the Kingdom Fungi.
