The wacky history of cell theory - Lauren Royal-Woods

[@user-ud6ps8uh4g]

*Here are some homework helpers:* -all organisms are made of one or more cells -a cell is the basic unit of structure and function in living things -all cells come from pre-existing cells Zacharias Jansen - microscope Anton Van Leeuwenhoek - discovered bacteria Robert Hooke - named cells Theodore Schwann - discovered all animals have cells Matthias Schleiden - discovered all plants have cells Matthias Schleiden working with Theodore Schwann - 4:10

you need to know that i love u

[@kryptal2]

This might help. 1. How was bacteria first discovered? Anton van Leeuwenhoek discovered bacteria by looking at the stuff on his teeth under a microscope. 2. How did Robert Hooke come up with the term "cell"? He came up with the term after looking at a piece of cork under his microscope, and it reminded him of cells, so that's what he named them. 3. How did Rudolf Virchow contribute to the cell theory? He showed that cells do come from other cells, although his proof was "taken without permission."

[@scuffedpianoguy5819]

This is going to be long, but it does have time stamps in case you want to watch the video. This is a quick summary of each person/topic in the video. School :P Cell Theory states : 0:45 1. All organisms are composed of one or more cells. 2. The cell is the basic unit of structure and organization in organisms. 3. All cells come from preexisting cells. Zacharias Jansen : 1:12 Created the first compound microscope and telescope. Anton Van Leeumenhoek : 1:38 discovered bacteria. He called them "Animalcules". Robert Hooke : 2:42 dabbles in lots of kinds of science. Discovered and names the cell after looking at a cork. Named the cell after it reminded him of prison cells or monk rooms. Hated Issac Newton. Mat Thias Schleiden : 4:10 German scientist who discovered all plants are made of cells. Theodore Schwann : 4:28 A German Scientist who discovered all animals are made of cells. Invented a re-breather for firefighters. Worked with Schleiden to create the "cell theory". He proposed that all cells come from other cells, but Schleiden did not agree. Schwann was proven right by a man named Rudolf Virchow. ( 4:53 ). Rudolf Virchow : 5:19 "proved" cells come from other cells. Stole his research from a Jewish scientist named Robert Remack. Robert Remack : 5:29 A Jewish scientist who truly proved cells come from other cells. Hated Rudolf Virchow.

Hope this helps What are the three parts of the Cell Theory? 1. All living things made up of cells. 2.Cell is the most basic unit of life 3. All cells must come from pre-existing cells. How did Leeuwenhoek discover bacteria? He discovered bacteria by looking at dental scrapings. As people did not brush their teeth often or did not brush at all. So he just look at his teeth. Before it was called "Bacteria"what was it called? Animalcules Who came up with the term "cell"? Robert Hooke looked at a piece of cork and saw chambers that looked like cells that monks slept in their monasteries.
