HSC Biology | Study Notes Gas exchange in plants is a key part of NSW Biology Stage 6, Module 2, Organisation of Living Things . This topic matters because Module 2 specifically includes investigating gas exchange structures in plants, including leaf structure, and linking plant structure to processes such as photosynthesis and transpiration. It also sits within the broader Module 2 focus on how multicellular organisms exchange nutrients, gases and wastes with their environments. In this...

HSC Biology | Revision Notes This topic matters because Module 2 asks students to investigate the structure of autotrophs, the function of structures in plants, and plant vascular systems as part of understanding how multicellular organisms exchange nutrients, gases and wastes. In this lesson the main functions of roots, stems and leaves what xylem and phloem are how plant tissues support transport how plant structures relate to function Why plant structures matter Plants are multicellular...

HSC Biology | Study Notes This topic matters because Module 2 specifically asks students to compare the nutrient and gas requirements of autotrophs and heterotrophs, and to link these requirements to the structures organisms use for photosynthesis, digestion and gas exchange. In this lesson the definitions of autotrophs and heterotrophs the main nutrient requirements of each the main gas requirements of each clear examples of autotrophs and heterotrophs What is an autotroph? An autotroph  is...
