Today I was observing a piece of cork and noticed honey comb-like structures. I decided to name the unknown structures "cells."
Today while I was observing plants with a microscope, I noticed that there were little ovals in the center of the plant's cells. I knew these were of great importance so I named them the nucleus of a cell.
After lots of research and observation on plants, I have concluded that all plants are made of cells.
After studying many live specimens. I have discovered that animals are made completely of cells.
Along with proving that cells come from other cells, I also traced diseases to be linked to cells.
The cell theory is made up of three parts. First, all living things are made of cells. Second, cells are the smallest building block of life. Lastly, all cells come from other cells through cell division. These are the three tenets to cell theory.
