Module 2 | Organisation of living things
Content 2: Nutrient and gas requirements
Lesson 1 | Investigating the structure of autotrophs
-
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
Lesson 2 | Range of imaging techniques
-
using a range of imaging technologies to determine plant structure
Lesson 3 | Investigate the gas exchange structures in animals and plants
-
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
Lesson 4 | Hypothesis, theories and models
-
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
Lesson 5 | Transpiration-Cohesion-Tension theory
-
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)
– transpiration-cohesion-tension theory
Lesson 6 | Mammalian digestive system
-
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
