Not always. Sometimes, during protein synthesis, the DNA of bacteria makes a mistake and copies the wrong protein causing a defect. This can cause the bacteria in the same colony to be slightly different. Also, bacteria can evolve very quickly, so this can also cause the bacteria in one colony to be slightly different.
If a colony of bacteria starts with one cell and doubles 12 times, the population can be calculated as (2^{12}). This equals 4,096 bacteria in the colony.
This is called binary fission.
Isolated colonies of bacteria are the result of a single bacterium which has replicated many times and eventually formed a visable lump of genetically identical bacteria. The colony's shape, texture and colour can somtimes be helpful in identifying the species of bacteria. For example collonies of Serratia marrceccens are typically pink, moist looking, round and small on nutrient agar. I laymans terms isolated colonies are the single separated spots (normally semi-spherical like zits) on the plate after it has been incubated. If the bacteria are put on the plate too close together they will form a lawn which looks like the whole plate is covered evenly.
One parent produces offspring that are exact copies of the parent.
Not really. It is likely that some microorganisms stick with each other, and is simply not separable by simple streaking. Sometimes the organisms exist in a bundle together, and all of these lead to the growth of one colony. Hence, microbiologist usually use the term "Colony Forming Unit" (CFU) to represent the origin of a colony, be it only one organism, or more than one.
A colony is a visible cluster of bacteria that has grown and divided on a solid agar surface. Each colony arises from a single bacterial cell and represents a genetically identical population of bacteria. Colonies can vary in size, color, shape, and other characteristics depending on the type of bacteria.
It is important for someone who works with bacteria to have a genetically identical bacterial colony so they can test different things on one type of bacteria. Making observations on that one colony is valuable for visual research and identification of that microorganism.
If a colony of bacteria starts with one cell and doubles 12 times, the population can be calculated as (2^{12}). This equals 4,096 bacteria in the colony.
A group or cluster of bacteria derived from one common bacteria.
Two identical cells
This is called binary fission.
All it takes is one bacteria. The cell's divide by binary fission where the microbes DNA splits to form a new cell.
Bacteria typically divide through a process known as binary fission, where one bacterial cell duplicates its DNA and then splits into two identical daughter cells.
Isolated colonies of bacteria are the result of a single bacterium which has replicated many times and eventually formed a visable lump of genetically identical bacteria. The colony's shape, texture and colour can somtimes be helpful in identifying the species of bacteria.

One parent produces offspring that are exact copies of the parent.
The minimum number of bacteria present on a plate is 1. Depending on how well the bacterial colony was isolated, there may be different kinds of bacteria present.
The most common bacterial reproduction is by Binary Fission, which is the use of mitosis to create two identical cells from one. Rarely, bacteria can reproduce sexually (ie using meiosis to create genetically different daughter cells) but this is not the most widely used mechanism.
