Cell Theory

The combined observations of Mattias Schleiden, Theodor Schwann and Rudolph Virchow resulted in the formation of the cell theory. Which of the following is not part of the cell theory?

• All cells contain a nucleus. 
• All cells come from other living cells.
• All living organisms are made of one or more cells
•  Cells are the basic unit of structure and function of all living things.

The Cell Theory:

1. 1. All living organisms are composed of one or more ​ (a)   . (Unicellular or Multicellular)

2. 2. All cells arise from ​ (b)   cells. (Not from Spontaneous Generation)

3. 3. Cells are the structural and functional unit of ​ (c)   . (Nothing living smaller than a Cell)

• cells
• preexisting
• life

Put the components of Cell Theory in their investigative order:

• all organisms are composed of cells

• all cells come from pre-existing cells

• cells are the basic unit of life

What are the three main components of the cell theory?

• Cell is the basic unit of life, all living organisms are composed of one or more cells, and all cells come from pre-existing cells

• Cells can spontaneously generate from non-living matter

• All living organisms are composed of non-living material

• Cell is not the basic unit of life
