C.3.1 - cells, tissues, systems

• Advantages of multicellularity

  • Division of labour
  • Specialized organelles can do functions better than one cell doing everything
• Advantages of multicellularity

  • Size
  • Multicellular organisms can be big by just adding more cells, and can develop transport systems for more effective transport
  • Single cell organisms are restricted by their cell size
• Advantages of multicellularity

  • Interdependence
  • Life of multi cell organism doesn’t depend on 1 cell
  • In a single cell organism, if 1 cell dies the whole thing dies
• • Tissues - groups of cells working together
  • Organs - group of tissues working together
  • Organ systems - group of organs working together
• Meristems - areas that have greater rates of cell division cause it can happen at different rates
