Despite this, the microscope soon became a hot item that every naturalist or scientist at the time wanted to play with.

It looked more like a tiny paddle the size of a sunglass lens.]]> 2021-11-23 23:48:40 UTC https://padlet.com/student192052/nrszgbqmyjabq7kz/wish/1909429671 student192052 https://padlet.com/student192052/nrszgbqmyjabq7kz/wish/1909430152 Once Leeunwenhoek had his microscope ready, he went to town and by looking at different items he discovered bacteria by looking at his teeth. He wrote about his discovery, he didn’t call bacteria “bacteria'', he called them: Animalcules because they looked like little animals to him.

He named the cell “cell”. As he was looking at a piece of cork under his microscope and the little chambers he saw reminded him of cells, or the rooms monks slept in their monasteries.

Newton wanted to erase all the evidence of the study and some portraits of Hooke but after Newton’s time, they discovered all the studies he had been trying to destroy. (Newton had the opportunity to destroy Hooke’s portrait so anyone knows what he looks like).

From these years of studying different plant species, it finally dawned on him that every single plant was all made of cells. Theodor Schwann, a scientist who studied slides of animal cells under the microscope and got a special type of nerve cell named after him. After studying animal cells for a while, he too came to the conclusion that all animals were made of cells, Schleiden and Schwann started working on the beginnings of the cell theory. For the last part of the cell theory, Schwann thinks cells come from preexisting cells but Schleiden as he swore cells came from the free-cell formation.
