Key Topics to Revise

1

Cell Cycle and Its Phases

  • Cell cycle is the period from the end of one division to the end of the next division (10-30 hours in eukaryotes)
  • Actual division takes only 30 minutes to 1 hour
  • Cell cycle has two main phases: Interphase (90%) and Division phase (10%)
2

Mitosis - Somatic Cell Division

  • Mitosis was discovered by W. Flemming
  • Also called somatic cell division or equational division
  • Occurs in meristem, cambium, epithelium, bone marrow cells
3

Cytokinesis in Plants vs Animals

  • Animal cells: Cleavage furrow forms at equatorial plane
  • Animal cytokinesis: Centripetal division (inward from periphery)
  • Plant cells: Cell plate formation from Golgi-derived vesicles
4

Meiosis - Reduction Division

  • Term coined by Farmer and Moore
  • Occurs in reproductive cells (anthers, ovules, testes, ovaries)
  • Produces four genetically different haploid gametes
