How do you differentiate the colony of yeast and fungus in petri plates?

Yeast colonies will generally be round, smooth, and look wet. (They may or may not be shiny.) Hyphal fungi may or may not be round; they will look more thread-like, stringy, and wispy. Hyphal fungi may also appear powdery due to the production of conidia. (A yeast is a fungus.)

How does the bacteria remain uncontaminated when the covers slightly ajar after pouring nutrient agar into petri dishes?
This may be a better way to ask this... When pouring Nutrient agar into Petri plates, the procedure instructs you to keep the covers slightly ajar. Explain why the plates don't get contaminated from organisms suspended in the air?
What is a two-piece glass or plastic dish used for growing bacteria or mold?
A "petri dish"

How did Robert Koch discovery being used today?

Why are inverted plates during incubation?
Because during incubation moisture will form at the top of the petri dish. Inverting the dish prevents it from dropping into whatever you have in the petri dish.

What is the value of petri plates in micro biology?
The facecious answer is about 20 cents. Petri dishes are used to grow all manner of micro-organisms using a variety of media (food) for the bugs to grow on. Penicillin was discovered accidently growing on a petri dish this accidental discovery has saved probably 100s of millions of lives.
