primordium
Sign in to savethumb|250px|right|Root primordia (brown spots) as seen on the butt of a freshly cut [[pineapple crown intended for vegetative reproduction]] A primordium (; : primordia; synonym: anlage), in embryology, is an organ or tissue in its earliest recognizable stage of development. Cells of the primordium are called primordial cells. A primordium is the simplest set of cells capable of triggering growth of the would-be organ and the initial foundation from which an organ is able to grow. In flowering plants, a floral primordium gives rise to a flower.

Although it is a frequently used term in plant biology, the word is used in describing the biology of all multicellular organisms (for example: a tooth primordium in animals, a leaf primordium in plants or a sporophore primordium in fungi.)
