LS1-4 Cellular Division/Mitosis

Biology and Life Science Safety Guidelines

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.

  • 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
