Nutrient and Gas Requirements
What is the difference in nutrient and gas requirements between autotrophs and heterotrophs?
Inquiry Question
Overview
- Investigate the structure of autotrophs through the examination of a variety of materials, for example:
- Dissected plant materials
- Microscopic structures
- Using a range of imaging technologies to determine plant structure
- Investigate the function of structures in a plant, including but not limited to:
- Tracing the development and movement of the products of photosynthesis
- Investigate the gas exchange structures in animals and plants 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:
- 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
