investigate the structure of autotrophs through the examination of a variety of materials, for example: (ACSBL035)

• dissected plant materials (ACSBL032)

• microscopic structures

• using a range of imaging technologies to determine plant structure

TEXT

investigate the function of structures in a plant, including but not limited to:

• tracing the development and movement of the products of photosynthesis (ACSBL059, ACSBL060)

text

investigate the gas exchange structures in animals and plants (ACSBL032, ACSBL056) through the collection of primary and secondary data and information, for example:

• microscopic structures: alveoli in mammals and leaf structure in plants

• macroscopic structures: respiratory systems in a range of animals

interpret a range of secondary-sourced information to evaluate processes, claims and conclusions that have led scientists to develop hypotheses, theories and models about the structure and function of plants, including but not limited to: (ACSBL034)

• photosynthesis

• transpiration-cohesion-tension theory

trace the digestion of foods in a mammalian digestive system, including:

• physical digestion

• chemical digestion

• absorption of nutrients, minerals and water

• elimination of solid waste

compare the nutrient and gas requirements of autotrophs and heterotrophs
