Used to spread microorganisms on an agar plate
Usually hundreds of colonies (>300) is considered as a high plate count.
No It is considered a continental plate although it does cover some ocean
The Aegean microplate, that used to be considered a part of the Eurasia plate.
Yes, each colony that forms on the plate was the result of a single microorganism. If you can know the quantity of the unit sample, you can know the number of microorganisms that were in that sample by counting the colonies.
Used to spread microorganisms on an agar plate
Williston et.al and waksman et.al discovered the crowdwed plate technique.
In the pour plate, the microorganisms will grow within the gel that has been set, and in the spread-plate technique, growth will be on top of the agar gel where it has been spread.
Usually hundreds of colonies (>300) is considered as a high plate count.
In the broadest terms, a group of microorganisms can be an ecosystem of its own, or a population. For example the group of microorganisms that inhabit your mouth are the population of your oral cavity. A species is every organism that exhibits the same DNA (within reason, there are so many ways DNA can be mutated) and key features. The most often time you see a group of microorganisms may be on a agar plate, after incubating the plate you've streaked with bacteria. In this case the groups, or blobs, are called 'colonies'. While each colony has millions(!!) of bacterial cells in it (hence why you can see it!), they all came from one bacteria. Because we know this we can count the number of colonies and know how many bacteria were originally on the plate, somethings microbiologists call CFU, or Colony-Forming-Units. Many examples in food and beverage industry involved maximum CFU values per mL of beverage or gram of food for it to pass inspection. This is how it is determined.

The Aegean microplate, that used to be considered a part of the Eurasia plate.
The standard plate count is performed so that the number of microorganisms found in a single gram of food can be determined. To be considered standard, there needs to be a minimum of 25 colonies on the plate.
Volcanic eruptions, earthquakes, plate tectonics,
Yes, each colony that forms on the plate was the result of a single microorganism. If you can know the quantity of the unit sample, you can know the number of microorganisms that were in that sample by counting the colonies.
Yes, stealing license plate is still considered theft.
no.,clearing your plate in china is considered rude
