1) The bottom of the plate contains the agar and your experiment, if the lid gets lost but the bottom is labled you haven't lost any work. If you label the lid and the lid gets lost you won't be able to identify your experiment. You would have to start from the beginning, making plates, sterilizing plates, doing the experiment; perhaps not an option if it were a clinical sample.
2) The plates are placed in the incubator with their bottom half upper most. This is done to prevent droplets of moisture falling from the lid and smearing the culture. As the bottom is upper most when you are looking in the incubator it makes sense to label the bit you can see most easily.
Candida fungi typically appear as white to cream-colored colonies on Petri plates. These colonies can vary in texture and may have a smooth or waxy appearance.
If media splashes up the side of a petri plate, it can result in contamination from the outside environment or other plates. It may also affect the growth of the culture as the splashed media can mix with the top agar layer. To prevent inaccurate results and contamination, it is best to discard the petri plate.
Petri plates are essential tools in microbiology for culturing and growing bacteria and other microorganisms. They provide a solid surface for microbial colonies to grow and are used for isolating and identifying microbial species. Petri plates are also used for testing the effectiveness of antibiotics and disinfectants.
Slants are primarily used in microbiology to provide a larger surface area for microbial growth compared to agar deeps or plates. They are commonly used for the maintenance and storage of microorganisms, as well as for the evaluation of motility and oxygen requirements of bacteria.
A Petri dish may be sealed with sticky tape to prevent contamination from airborne particles or other microorganisms present in the environment. This helps maintain a sterile environment for bacterial or fungal cultures to grow without interference.
No. It will contaminate the plates.
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

Petri dishes should be labeled on the bottom, not the lid, to prevent smudging or mixing up. Use a waterproof marker to write the date, experiment details, and any other relevant information clearly. Store the labeled dishes in a clean, dry area to prevent contamination.
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.
Candida fungi typically appear as white to cream-colored colonies on Petri plates. These colonies can vary in texture and may have a smooth or waxy appearance.
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.
Labeling petri dishes correctly is important for proper identification of the samples being studied. This helps prevent mix-ups, ensures accurate data collection and analysis, and allows for traceability in case of any issues or discrepancies.
Flaming the edges of the petri plates before pouring the media helps to create a sterile environment by killing any microorganisms present on the surface. Flaming the edges after pouring the media helps to prevent contamination of the agar surface by airborne microorganisms during incubation.
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?
Equipment commonly used to grow bacteria includes petri dishes, agar plates, incubators, loop inoculators, and pipettes. These tools provide a controlled environment for bacteria to grow and can help researchers study their characteristics and behaviors.
Petri Liski's birth name is Petri Juhana Liski.
