Robert Hooke added a third lens to microscopes
He also looked at a cork and found that it was full of air pockets
Documented the first cells -
He used the one lens to look at orginisms and found living cells.
Gave the name Protista for the moving cells -
He conducted a test that used a piece of meat in a jar. One jar was sealed with a lid, one was capped off with gauze and one was open. Only the open one produced maggots. People still believed that life happened spontaneously
-
He wanted to prove it right so he boiled chicken broth and put it into a sealed container. Micro-organisms still formed
-
He spotted an opaque spot in a cell. It is the nucleus. It was seen before but he thought it was important
-
He was the one that thought that the nucleus controls everything
-
He was the one who said that we should look at animal cells He realized that the animal cells have nucleus as well as animals
-
He conducted the same experiment as John but he made sure that the flask was clean and he also made a long curvy neck of the bottle. By itself no micro-organisms formed but when he tipped it on its side and righted it again micro-organisms were formed.
