What is the function of a pietri dish?
A petri dish is a flat dish made of either plastic or glass. It is used primarily to grow a culture of bacteria.
What is the funcion of a petri dish?
A petri dish is a flat dish made of plastic or glass with a cover that is primarily used to grow bacteria. However, the petri dish can be used to view seed germination or for viewing small animal observations. Petri dishes fit conveniently under a dissection scope (stereomicroscope) and is often used as a platform for viewing any small objects. Other applications are possible as well.
Does a petri dish melt if microwaved for 3 minutes?
Petri dishes are generally made out of glass, so they will not melt if microwaved. If it is made of plastic, it may melt - but I would not expect it to.
What is pitridish?
A petri dish is a round, shallow container made of glass or plastic. It is used to culture bacteria and tissues.
Small dish made of ceramic material?
Its called a crucible or a crucible with lid hopes this helps!
What substance goes in a petri dish?
Any microorganism such as bacteria etc. *Agar jelly, a substance normally made from seaweed and is very nutritious for bacteria, moulds, etc.
Use of petri dishes?
A petri dish is a type of glass or plastic shallow round dish with a close fitting lid which is a vital tool in scientific laboratories. The uses for the petri dish are varied, but it is most well known for holding a culture medium upon which cells, bacteria, and viruses can be grown and studied. Most major scientific breakthroughs have been greatly assisted by the use of petri dishes whether they involve the structure of a virus or the ability to clone meat. The invention is named for Julius Richard Petri, who conceived of the idea in 1877, frustrated with existing tools for cultures. Most scientists used shallow bowls or bottles, which were awkward to work with and subject to contamination. Petri thought that a shallow circular dish would be easier to work with, and easy to make a lid for. The lid keeps the petri dish from being contaminated, and the basic shape makes them easy to stack and arrange in varied configurations. When a petri dish is used to culture cells, it is usually filled with a growth medium made from agar, a gel made with extracts from red algae, and a variety of nutrients. The growth medium has a gelatinous texture which most cultures thrive on, although sometimes the nutrients need to be varied to meet the needs of the organism being cultured. To satisfy the needs of finicky organisms, a scientist may take several weeks to adjust the environment of a series of petri dishes. Once the culture starts to thrive, the organism can be researched. There are other uses for the petri dish: many schools, for example, use them to teach students about seed germination, as the clear dish allows the observer to see every step of growth. In addition, the petri dish is commonly used for dissection, because it is ideally sized to be placed under a microscope. A petri dish can also be used for basic experimental purposes like transporting liquids in sterile containers or drying fluids for study. Other uses for the petri dish are constantly being explored by the scientific community, and it is a laboratory tool that is unlikely to be abandoned in the near future. Major advancements in science such as growing cells integrated with electronic circuits, cloning organs, and understanding viruses have been accomplished with the aid of the humble petri dish. Although other methods of studying organisms in the laboratory are being developed, the need for the basic ability to culture organisms rapidly in a sterile environment will never fade.
What is a petri dish culture?
The intentional growth of cells, fungi, bacterium, etc is a small isolated container usually lined with a nutrient which promotes the growth of the culture. The petri 'dish' is (usually) made of glass and is round with a relatively large diameter compared to its short sides as opposed to "test tubes" and "beakers" which have tall sides, and "flasks" that have sides with uneven diameters usually smaller at the top.
Who invented the antibiotic Penicillium?
Alexander Fleming invited the antiobiotic called Penicillium in the year 1928. Alexander Fleming was a bacteriologist and made the discovery of Penicillium by chance from a contaminated Petri dish.
How was pencillium found?
In 1928, bacteriologist Alexander Fleming made a chance discovery from an already discarded, contaminated Petri dish. The mold that had contaminated the experiment turned out to contain a powerful antibiotic, penicillin. However, though Fleming was credited with the discovery, it was over a decade before someone else turned penicillin into the miracle drug for the 20th century. How did this Petri dish almost get cleaned before being noticed? How did the mold get onto the dish? Who transformed penicillin into a useful drug?
What should you use to grow germs for a project?
Bacteria are usually grown in a shallow glass dish (a Petri dish, although you could use any dish) in a growth medium made of gelatin; you could use Jello. Viruses are trickier, they require living tissue of some sort. For an amateur, it's best to stick to bacteria.
