2 | Patterns in nature

4: Gaseous exchange and transport systems transfer chemicals through the internal and between the external environments of plants and animals

Lesson 1 | System roles

  • Compare the roles of respiratory, circulatory and excretory systems

  • Explain the relationship between the requirements of cells and the need for transport systems in multicellular organisms

Lesson 2 | Gaseous exchange -animals

  • Compare the roles of respiratory, circulatory and excretory systems

  • Identify and compare the gaseous exchange surfaces in an insect, a fish, a frog and a mammal

Lesson 3 | Circulatory systems in animals

  • Compare open and closed circulatory systems using one vertebrate and one invertebrate as examples

Lesson 4 | Transport systems in plants

  • Outline the transport system in plants including:
    – Root hair cells
    – Xylem
    – Phloem
    – Stomates and lenticels

Lesson 5 | Transpiration system in plants experiment

  • Use available evidence to perform a first-hand investigation and gather first-hand data to identify and describe factors that affect the rate of transpiration

  • Perform a first-hand investigation of the movement of materials in xylem or phloem

Lesson 6 | Role of technology

  • Use available evidence to discuss, using examples, the role of technologies, such as the use of radioisotopes in tracing the path of elements through living plants and animals
