Module 2 | Patterns in nature

Focus 3: Plants and animals have specialised structures to obtain nutrients from their environment

Lesson 1 | Organisation in organisms

  • Identify some examples that demonstrate the structural and functional relationships between cells, tissues, organs and organ systems in multicellular organisms

  • Distinguish between autotrophs and heterotrophs in terms of nutrient requirements

Lesson 2 | Photosynthesis

  • Identify the materials required for photosynthesis and its role in ecosystems

  • Identify the general word equation for photosynthesis and outline this as a summary of a chain of biochemical reactions

  • Plan, choose equipment or resources and perform first-hand investigations to gather information and use available evidence to demonstrate the need for chlorophyll and light in photosynthesis

Lesson 3 | Surface area and rate of reaction

  • Explain the relationship between the organisation of the structures used to obtain water and minerals in a range of plants and the need to increase the surface area available for absorption

  • Perform a first-hand investigation to demonstrate the relationship between surface area and rate of reaction

Lesson 4 | Leaves

  • Explain the relationship between the shape of leaves, the distribution of tissue in them and their role.

Lesson 5 | Digestive system in animals

  • Describe the role of teeth in increasing the surface area of complex foods for exposure to digestive chemicals

  • Explain the relationship between the length and overall complexity of digestive systems of a vertebrate herbivore and a vertebrate carnivore with respect to:
    – The chemical composition of their diet
    – The functions of the structure involved

Lesson 6 | Comparison of digestive systems

  • Identify data sources, gather, process, analyse and present information from secondary sources and use available evidence to compare the digestive systems of mammals, including a grazing herbivore, carnivore and a predominantly nectar feeding animal
