Hey there's a penguin on the beach that's weird! I know that penguin's are made of cells so all living things must be made of cells.
Plants are living things too! Cells must be the building blocks of all life.
I wonder how there are so many cells? I remember looking through a microscope one time and the cell split or duplicated. Wait that's it cells duplicate off of preexisting cells! Now I know cell theory!
Now that I know cell theory I'm gonna knock you out!
