The Latin term in<unk> , meaning "in glass", is used because early biological experiments involving cultivation of tissues outside the living organism were carried out in glass containers, such as beakers, test tubes, or Petri dishes. Today, the scientific term "in<unk> " is used to refer to any biological procedure that is performed outside the organism in which it would normally have occurred, to distinguish it from an in vivo procedure (such as in vivo<unk> , where the tissue remains inside the living organism in which it is normally found. A colloquial term for babies conceived as the result of<unk> , "test tube babies", refers to the tube-shaped containers of glass or plastic resin, called test tubes, that are commonly used in chemistry and biology labs. However,<unk>  is usually performed in Petri dishes, which are both wider and shallower and often used to cultivate cultures. In a broader sense,<unk>  is a form of assisted reproductive technology (ART).
