As valedictorian, the most important thing I learned was The Cell Theory. Cells are the basic unit of life structure and function of living things. All living things are made of cells. Cells come from pre existing. These statements are very important and vital and important for humans to understand. More interesting than the actual theory are the people that came up with it.
It all started in 1663, when an English scientist named Robert Hooke was examining a cork under his microscope. He noticed the small chambers inside of the cork and it reminded him of jail cells. From that, he coined the term cell.
The cork had a lot of chambers in it that looked like jail cells. I'll just call them cells.
Later on in 1833, Robert Brown discovered the center of the cell, or the nucleus. He found it inside of plant cells.
Then Matthias Jakob Schleiden, a German botanist, made the first statement of the Cell Theory in 1838. He proposed that all plant tissues are composed of cells, and that cells are the basic building blocks of all plants. This statement was the first generalized statement about cells.
After observing those plants under the microscope, I realized that all plants are made up of cells.
Shortly after in 1839, a German botanist, Theodor Schwann, reached the conclusion that not only plants, but animal tissue as well is composed of cells. He also wrote a book on his findings.
All plants and animals are made of cells.
Lastly, in 1855, Rudolf Virchow, a German physiologist, added the 3rd and last part to the cell theory. He proposed that cells come from preexisting or other cells.
