Answer:
In 1928, Sir Alexander Fleming was studying Staphylococcus bacteria growing in culture dishes. He noticed that a mold called Penicillium was also growing in some of the dishes. A clear area existed around the mold because all the bacteria that had grown in this area had died. In the culture dishes without the mold, no clear areas were present.
Fleming thought that the mold must be producing a chemical that killed the bacteria. He decided to isolate this substance and test it to see if it would kill bacteria. Fleming transferred the mold to a nutrient broth solution. This solution contained all the materials the mold needed to grow. After the mold grew, he removed it from the nutrient broth. Fleming then added the nutrient broth in which the mold had grown to a culture of bacteria. He observed that the bacteria died. He also added the same type of broth that had not been exposed to the mold, to a culture of the same type of bacteria. Nothing happened to the bacteria.

False it is does not have plants it can be release oxygen gas to the atmosphere
They carry out every reaction happening within the body, hence they sustain life.
DNA replication needs to occur because existing cells divide to produce new cells. ... So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!
