Which term refers to the growth of cells outside an organism on a sterile nutrient medium?

• A. Culture
• B. Cell culture
• C. In vitro culture
• D. Tissue culture

Answer: (D)

Growing tissue outside an organism on a sterile nutrient medium is tissue culture. This term highlights that the starting material is tissue (pieces of tissue or cells derived from it) and that the culture is maintained in a sterile, controlled environment on nutrient medium, allowing cells to survive and multiply away from the body. While culture is a general idea of growing something outside, and cell culture focuses on individual cells, and in vitro culture is a broad label for anything grown outside the organism, tissue culture specifically refers to tissue growing in vitro on a nutrient medium.
