LS1 4 Cell Division: Mitosis
Project Zero THINKING ROUTINES
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.]

Prior Knowledge/Preview
Origin of Cells
-
Cells can only be formed by division of pre-existing cells.
-
The first cells must have arisen from non-living material.
-
The origin of eukaryotes: described by the endosymbiotic theory
-
CELL DIVISION
-
Mitosis cell division into two genetically identical daughter nuclei
-
Chromosomes condense by supercoiling during mitosis. Longer description
-
Cytokinesis after mitosis--different in plant and animal cells.
-
Interphase -cell cycle's active phase
-
Cyclins and control of the cell cycle
-
Mutagens, oncogenes and metastasis are involved in the development of primary and secondary tumours
