Which technology involves growing cells in controlled conditions outside the living organism?

• A. Computer models
• B. Tissue cultures
• C. Both
• D. None

Answer: (B)

In vitro growth of cells outside the organism is called tissue culture. It involves keeping cells in sterile containers with defined nutrients and conditions (temperature, carbon dioxide, humidity) to support their growth and sometimes differentiation, all away from the whole living body. This controlled environment lets researchers study cell behavior, test drugs, or produce biological products in a reproducible way. Computer models, while useful for simulating biological processes, do not involve actual cell growth, so they don’t fit the description of growing cells outside a living organism.
