Final answer:
Tissue culture is a technique in biology that involves growing and maintaining cells outside their natural environment. This is done by taking healthy cells from an organism and placing them in a culture medium to facilitate cell growth and multiplication.
Step-by-step explanation:
Tissue culture is a technique used in biology to grow and maintain cells outside their natural environment. The process involves taking a small sample of healthy cells from a living organism, and placing them in a culture medium that provides the necessary nutrients and conditions for cell growth. The cells are then incubated in a controlled environment, allowing them to multiply and form a culture of cells that can be used for various scientific and medical purposes.
