Initially, he used these lenses to look at the details of his linen. But driven by obsession and curiosity he began to look at other things like fleas, bumble bee stings, and lake water. The latter is the most important thing he could have looked at thus far. “He noticed that the lake water changed color with the seasons and he figured that [if he looked at the water under his lens, he could find out the cause.]” (The Cell: The Hidden Kingdom) Under the lens he saw tiny creatures that “pirouetted” and swam here and there. (The Cell: The Hidden Kingdom) “This was to me among all the marvels that I have discovered in nature the most marvelous of all. No greater pleasure has yet come to my eye than these spectacles of so many thousands of living creatures in a small drop of water, moving among one another,” he wrote. He assumed that he had discovered a miniature version of the universe, with animals and all, reason for which he named the creatures he saw animalcules. Excited about his discovery, he wrote a letter describing such sight and accompanied it with drawings of what he saw and sent it over to the Royal Society in London. In reading the letter, the Royal Society scientists were also curious and used their own microscopes to have a look for themselves but they never found any of the creatures Leewenhoek claimed to have found. They were …show more content…
However, they had made a mistake regarding where new cells come from. They thought that new cells formed spontaneously, but this was busted by Louis Pasteur. Rudolf Virchow and Robert Remak “searched for [an] explanation for the origin of cells.” (The Cell: The Hidden Kingdom) Remak collected blood from chick embryos and looked at the blood under his microscope. He saw red bloods cells, some of which were dividing. This new finding gave way to the understanding of how new cells form. Remak shared his findings with Virchow, who then stole his ideas and published them as his own. As we have learned in class new cells form from old cells through the process of meiosis and mitosis. In meiosis, chromosome pairs synapse, cross over, align, and separate twice. The crossing over results in the mixing of genetic information between the chromosome pairs. When they separate, they divide and form four cells with varied genetic material, resulting in offspring that are varied forms of their parents. In mitosis, chromosomes divide and form two cells with no change in genetic material, resulting in offspring that are exact copies of the parent. And so, like this, one cell forms from another, and continue to do so, each time increasing the possibility of a new
