- Kingdom containing multicellular organisms having cells bound by a plasma membrane and organized into tissue and specialized tissue systems that permit them to either move about in search of food or to draw food toward themselves. Unable to make their own food within themselves, as photosynthetic plants do, they rely on consuming preformed food. They possess a nervous system with sensory and motor nerves, enabling them to receive environmental stimuli and to respond with specialized movements.
- A baked or semi-fired material that is usually a mixture of clay, grog, and water; it has been used for pottery, statuettes, lamps, roof tiles, and cornices since ancient times.
