In 1665, Hooke published his own book, Micrographia, where he explained about his research on dead cells and that the tiny cells looked like apartments monks lived in at monasteries. A few years later, Antonie van Leeuwenhoek, a Dutch lens crafter, crafted special lenses and made his own telescope to observe live cells. But it was not until 100 to 150 years later that the basics for “modern cell theory” were developed. In the 1850s, Matthias Schleiden and Theodor Schwann were the first to lay down the basics for “modern cell theory”. Later, Robert Remak developed the idea that “All cells came from other cells”. But then, a man named Rudolph Virchow plagiarized Remak’s work and earned all the credit which was supposed to go to Robert Remak.]]> 2023-10-10 23:10:41 UTC https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2740744011 https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2740745599 EQ.                               Why can’t we see cells with our eyes?

  Secondly,the first person to notice cells was Robert Hooke. He had made a microscope and discovered that dead cells looked like homes monks used to live in. The homes where called cells, that’s how cells got there name.
  Then, I learned about Antonie Van Leevwenhoek. He was a lens maker and was inspired Robert Hooke. With the inspiration he made better lenses and studied live cells instead of dead.
  Also, these two men, Schlien and Schwan thought of ideas based of off of what they knew about cells. They thought of 3 things. 
   1.maybe all living things are made of cells?
   2. A cell is a basic unit of life.
   3. All cells come from other cells.
  Lastly, there where these two people named Remak and Virchow. They both studied cells but all of Remak’s work was plagiarized Virchow and Virchow took the credit.
   And that is what I learned in the Khan Academy video on the Cell Theory.]]> 2023-10-11 02:43:51 UTC https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2741009596 https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2741076720 In this lesson, I learned about the discovery of cells. I learned about Robert Hooke, who made the first microscope. Hooke also examined dead cells and wrote a book called Micrographia in 1665. In Micrographia, he sketched the dead cells he saw. Then, because he noticed that the cells had monastery-like compartments, he called cells: cells. So that is how cells were first discovered and named. Then, Antonie van Leevewehook(I don't know how to spell his name properly) began looking at living cells instead of dead ones and made observations. Leevenwehook was also a lens maker for microscopes that made it possible to look through microscopes with more detail. Finally, Schuleiden and Schwann began to wonder if all life is made of one or more cells or if cells are the basic unit of life. So Schwann decided to do rigorous research and concluded that the answer to both was yes. However, Schuleiden stole and plagiarized the work until future research was made and learned that Schuleiden had lied. So finally, the discovery of cells has let us learn about many medical phenomenons. Without all of these scientists, many diseases and injuries would be life-threatening and nobody would know why. Today, some of my questions included: How many cells die a day? Could cells be found on non-living things(if blood was thrown onto a wall and cleaned)? Do children have different cells? Why do animal cells have a thicker barrier?]]> 2023-10-11 03:34:55 UTC https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2741076720 https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742233477 Humans have 37 trillion cells. The first person to discover cells was Robert Hooke. In 1665, Hooke decided to look at dead cork cells by using a simple magnifying glass. Hooke noticed that it looked oddly familiar. He thought of the rooms that monks inhabited called cellula and therefore named it after that. Later, Antoine Van Leeuwenhoek decided to take a closer look at this theory. He was the first man to see living cells sperm. Not only that, he was the first person ever to use a microscope.]]> 2023-10-11 17:36:43 UTC https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742233477 https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742268214 2023-10-11 17:57:59 UTC https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742268214 https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742453298 How did Robert Hook make the microscope?

In this video I learned about the theory of cells. First there was a man named Robert Hooke who invented the first microscope. Unfortunately this microscope only allowed him to see the dead tissue around the actual cell. Then came Antoine Van Leeuwenhoek who was a Dutch lens crafter. Using his knowledge on lenses he was able to craft a better microscope which allowed him to actually observe cells. Later in the 1800,s 2 men named Matthias Schneider and Theodor Schwaan believed that all life was created of one or more cells. Lastly in the mid 1800,s a man named Robert Remak developed a theory about cells saying that all cells come from other cells which is the theory that we still believe after all those years.]]> 2023-10-11 23:11:16 UTC https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742555463 https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742576803 In this lesson I learned all about Cell Theory. Did you know we are made up of 37 trillion cells. Now you are probably thinking that if there are that many cells how come we can’t see it with our own eyes. Well these cells are really tiny, and now matter how hard you try you will not be able to see your cells with the naked eye. But there is this thing called the microscope, which brings me to my next question who invented the microscope? It was invented by a man by the name Robert Hooke. He created this as a way to see cells. He invented this in 1665. Now over time another man came along his name Anthony Van Leewanhoek. He was inspired by Hooke and decided to make it better so he started making lenses and doing glass work. Did you know that all living things have cells if they doing not they are not classified as a living thing. As you get older the cells in your body start vanishing which causes you to slow down and eventually die, making you non-living.]]> 2023-10-11 23:40:01 UTC https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742576803 ianl3685_ https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742654726 Some things that i liked was that when you get hurt you get more cells. In 1665 Robert Hooke created the first microscope. He also made a book called the micrographia. In the micrographia he made drawings of cells. Around 100 years later Antoine vanleevanhook observed dead cells and alive cells more up close. The reason he was so good at observing cells was because he was a lens maker. Around 50 years later in the 1830s two people from Germany schliden and Schuan thought of the cell theory and that cells are a basic unit of life.]]> 2023-10-12 00:42:18 UTC https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742654726 ianl3685_ https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742657104 2023-10-12 00:43:57 UTC https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742657104 mateos3213 https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742686904 2023-10-12 01:05:26 UTC https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742686904 https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742954765 The cell theory. We are made out of 37 trillion cells, the cell is the basic unit of life. Most of life is made out of 1 or more cells. All cells comes from other cells, a theory, was plagiarized by someone named Virchow. He got most credit that the original person, Remak. But Robert Hooke was the first person to see cells but only dead ones. He described it to be compartment where monks lived In. His book had drawings and observations about the cells and he would also study about lice and flees. Robert Hooke was looking at dead cells but another person named Antoine Van Leeuwenhoek was a Dutch lens maker. He thought since he was lens maker he could’ve made a better microscopes and he did just that. He was the first person to see living cells and he described it as animals. 2 other men named Schliemann and Schwan had 3 things that they knew about cells. One the thought that all living things are made out of 1 or more cells, that a cell is the basic unit of life and lastly all cells come from other cells.

If it wasn’t for Robert Hooke then we would have probably found out about how cells work not that long ago and he also made a book about his observations about the cells which was a very good idea, it is called “micrographia” this book changed the perspective of everything, we should all give a special thanks to Robert hook for taking his time to make a micro scope and make a book about how they work and look thank you Robert hooke.

In 1665 Robert Hooky saw dead cells for the first time. Robert Hooky was studying cells all of his science career. ]]> 2023-10-12 05:00:10 UTC https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2742988402 ezrap3763 https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2744113091 2023-10-12 18:51:52 UTC https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2744113091 naomif0010_ https://padlet.com/johnisaacson/vrnmr3mvnocy/wish/2744266663 The answer to the EQ is that the cells are just honestly too small.
What I learned is that the first person to ever discover the cell was a man named Robert Hooke. He looked under the first microscope, and saw this small little squares. He called them cells, after the housing of monks. Isaac Newton was said to have destroyed the only portrait of Hooke, so we don’t know how he looks. (I watched something on this so I already knew this.)
Later, Antoine von Leeuwenhoek discovers the LIVING cell. Hooke was only looking at dead ones. Leeuwenhoek was a lens-maker. He carved a lens to make a now-improved microscope.
Later, Matthias Schleiden and Theodor Schwann discover the first two rules of our modern cell theory:
1. All life is based from cells
2. The cell is the basic unit of life
The third rule did not come until later. Schleiden and Schwann did witness cells reproducing, and thought that some cells reproduced, while others just… spontaneously emerged. 
Even later, Robert Remak studied cells some more, and discovered the third rule of the cell theory: 
3. All cells come from other cells.
Sometimes the credit goes to Rudolf Virchow, but actually, he plagiarized Robert Remak! 
People are still trying to figure out how to explain that, because cells have to have come from SOMETHING back in the very beginning!
