What is a colony of bacteria?

A colony of bacteria, sometimes referred to as a culture, is simply, a single type of bacteria that replicates itself many many times and forms a small mass. In order to see a colony of bacteria, typically a species will be placed on a nutrient rich media, like agar for instance in a petri dish. This newly innoculated agar will be placed in an incubator at the optimal temperature for that given species of bacteria. After 24 hours, a once spotless agar plate will be covered in tiny dots, these are the colonies beginning to grow. Millions of bacterial cells can be procuced from one single original cell, which multiplies exponentially. 1 becomes 2,4,8,16,32 etc.....................until you have millions. I hope that answers your question!
