Why is it important to invert a petri plate during incubation?
Mommi
This is to stop condensation from forming on the top of the lid. Condensation causes two problems (1) It will allow contamination to enter into the dish by moving accross the water film from the outside (2) It can create a tight seal and prevent oxygen entering the petri dish making it go anerobic.

Why are petri plates inverted for incubation?
it is to prevent the moisture formed due to condensation of the agar ,to mix with the components present in the petri plates, else causes contamination

How do you use an petri dish?
a petri dish is used to study small things
What is Julius Richard Petri known for?
Julius Richard Petri is known for being the inventor of the petri dish. In early bacteria studies, cultures were kept in lidless dishes and as a result they often became contaminated. Julius Richard Petri invented a dish with a lid that reduced the risk of contamination and this has become known as the petri dish.
Tools scientist use?
The list is so exhaustive that I'm not even going to try, but I'll tell you about the tools/equipment I use. I study geophysics, and often have to collect data to try and understand the structure of the Earth. I use magnometers to measure the magnetic field strength, gravimeters to measure the gravitational field strength, terrameters (and occasionally something called an EM34) to measure the resistivity of the immediate subsurface, and a seismometer with an array of geophones to detect irregularities (such as geological changes) using seismic waves.
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.

Why should you label the petri dishes correctly?
The importance of labeling petri dishes is important. When looking at reaction on specimens or the growth of bacteria of items in a petri dish, if it is labeled incorrectly the data will be wrong and projects could be jeopardized.
Why petri dish need to be wrapped during sterilization?
They may be contaminated MORON.
Why petri dish is inverted in incubation in membrane filtration method?
This inversion prevents moisture condensing on the surface of the plate. That would make a problem in that the growth on the plate would be "distorted" by the water making ID more difficult.

How do you grow bacteria using a petri dish?
To grow bacteria on a petri dish, you will need several items.First you will need a petri dish with lid. The petri dish must contain agar, which is the source of the nutrients for the bacteria you want to grow.Then you will need sterile cotton tipped applicators. They must be sterile so that the bacteria you put in your dish is the only bacteria there, and not extra from an exposed cotton swab. There are also other laboratory tools that can be sterilized to pick up bacteria with.Then you need your source of bacteria.When you know what type of surface you will be swabbing, isolate one area, and swab it thoroughly with the cotton tipped applicator. Then, immediately swab it gently onto the agar surface with a back and forth motion.If testing two different specimens with one petri dish, be sure to only swab half of each side with each specimen. On the bottom of the dish, use a marker to note which side contains which sample.After preparing your petri dishes, place the lid on them and be sure they are labeled for easy identification. Then your specimens need to be incubated. Different types of bacteria thrive better at different levels of incubation and time. See a laboratory manual for incubation times.
