Curriculum content descriptions

Multi-cellular organisms contain systems of organs carrying out specialised functions that enable them to survive and reproduce (ACSSU150)

Elaborations
  • identifying the organs and overall function of a system of a multicellular organism in supporting the life processes
  • describing the structure of each organ in a system and relating its function to the overall function of the system
  • examining the specialised cells and tissues involved in structure and function of particular organs
  • comparing similar systems in different organisms such as digestive systems in herbivores and carnivores, respiratory systems in fish and mammals
  • distinguishing between asexual and sexual reproduction
  • comparing reproductive systems of organisms
