What is a colony of microorganisms?
A population of microorganisms living in association with each other
How do most microbes live?
As biofilms in association with each other on surfaces
What happens to the size of a colony as the number of cells increases?
It grows in size
Match the following terms with their definitions:
Colony = A visible population of microorganisms arising from a single cell Biofilm = Microbes living in association with one another on surfaces Microorganism = A single cell or colony-forming unit Population = The number of cells in a colony
Match the following descriptions with the appropriate term:
Visible population of microorganisms arising from a single cell or colony-forming unit = Colony Microbes living in association with one another on surfaces = Biofilm A single cell or colony-forming unit = Microorganism The number of cells in a colony = Population
