I wonder what are made of cells? Maybe I'm made up of cells?
Now lets see what i'm made up of.
Matthais Schleiden has discovered that all plants are made of cells!
In the cell theory there are 3 components. The first is all organisms are composed of or more cells. The second is the cell is the basic unit of structure and function. The third is all cells come from pre-existing cells.
Plants are very interesting because they have a cell wall. They're made up of many different structures.
