HS-LS1-4. Use a model to illustrate the role of cellular division (mitosis) and differentiation in producing and
maintaining complex organisms. [Assessment Boundary: Assessment does not include specific gene control mechanisms or rote memorization of
the steps of mitosis.]

Origin of Cells

Cells can only be formed by division of pre-existing cells.
The first cells must have arisen from non-living material.
