Question
What do you think Fleming did with the culture plate with mould?
Solution
Alexander Fleming, the discoverer of penicillin, likely conducted further experiments with the culture plate with mould. He would have observed the mould more closely, perhaps under a microscope, to understand its structure and properties. He would have also noticed that the bacteria surrounding the mould were dying, leading him to investigate the mould's potential antibacterial properties. This would have involved isolating the mould and growing it in various conditions to see how it affected different types of bacteria. Through these experiments, Fleming was able to identify the mould as Penicillium notatum and discover its antibiotic properties, leading to the development of penicillin.

The main, or central, idea of the passage is Fleming's chance observation of the antibacterial properties of mold led to the discovery of penicillin as a treatment. How does the detail in bold develop the main idea?In 1928, bacteriologist Alexander Fleming was studying Staphylococcus, a type of bacteria that can cause serious infections. He grew the bacteria in small containers called petri dishes. One day he noticed that mold had accidentally been introduced into one of the petri dishes and was startled to see that there were no bacteria around the moldy area. Fleming correctly deduced that the mold had had an antibacterial effect; somehow it had prevented the bacteria from growing. Fleming identified the mold as the strain Penicillium notatum and called its antibacterial ingredient—which he was unable to successfully extract—penicillin. Fleming's discovery of penicillin's unique effect led to the eventual finding that it could be used to treat infections. Several years after his initial observation, scientists built on his work by extracting penicillin from mold and demonstrating its effectiveness as a treatment.It describes Fleming's everyday duties as a researcher.It indicates the unintentional nature of Fleming's discovery.It criticizes Fleming's procedures as unsanitary.Save answer
