Cell Theory/Multicellular and Unicellular Organisms

Cell Theory

The cell theory is a explanation of relationships between cells and living things. It states that all living organisms and things are made of cells and those cells come from other cells and the varieties are endless. This theory comes from three sentences,

-All living things are composed of cells.

-Cells are the basic unit of structure and function in all living things.

-All cells are produced from other cells.


Multicellular means what it basically is called. Something composed of many cell.


A unicellular is something composed of one cell.
