CELLS! Everything living is made up of cells. Some are made up of one and others are made up of billion
Mom, what are we made out of? Is my cat made out of the same things I am? What are other living things made out of?
Yes! Matthias Schleiden discovered that all plants have cells back in 1839. This was an incredible discovery
Even our plants?
And, in 1839, just one year later, Theodore Schwann discovered all animals are made of cells. This showed that cells are the smallest form of life and they are universal. All living things are based off of this
Wait, so where do all of these cells come from? How are they made?
That was discovered by Rudolph Virchow in 1858
Well, all cells come from other cells. During a cells life, it will split and make more exact copies of itself. And when it dies other copies of it will already exist.
Rudolph discovered that the cells would divide and would form larger more complex animals and plants. All cells share the same DNA code and are made from the other cells
Wow, who knew cell theory is so interesting. Now I know all organisms are composed of on or more cells, the cell is the most basic unit of life, and all cells come from preexisting cells. All thanks to these amazing scientists!
