A single bacterial cell is invisible to the naked eye. As that single cell grows and divides into new cells, however, it forms a visible pile of bacteria. In microbiology, we call this pile of bacteria a colony. A colony’s appearance can indicate a lot about the bacterial cells within, such as how they utilize nutrients ...

After transformation, bacteria are … WebA turbid broth culture of bacteria can have millions or billions of bacterial cells in a single milliliter! If we transferred bacteria directly from that tube to a petri plate, it would be impossible to count colonies since there would be an overwhelming amount of growth on the petri plate (often called a lawn of bacteria).
