Explanation: In a culture media bacterial reproduce to form cells called colony.

A culture is a media used in growing a population of bacteria. It could either be solid, liquid or semi solid.

A solid and semi solid media contains Agar (a solidifying Agent) that provides a platform for the bacteria.

The media contains nutrients source that supply the required nutrient needed for the bacteria growth this include extracts of protein, inorganic salt,carbohydrate and vitamins.

Culture should be done in a disease free environment to avoid contamination.
