Tissue culture

Tissue culture or  cell culture is a way to grow cells in a laboratory. Cells are taken, and put into in a flask or Petri dish. They can be grown on a growth medium, sometimes an agar plate. The cells divide, and can be treated in various ways.  This is done for a number of purposes, especially for the use of scientific research: 

Growing bacteria or fungi for experiments or for identification. An example would be growing bacteria to see what antibiotics they are resistant to.
Growing cells of plants or animals for various experimental purposes. 
Plant cuttings can be grown: roots grow out of a sprig. 
In-Vitro Fertilization is when eggs are taken and fertilized with sperm in the dish.
