Module 2: Organisations of Living Things

Question 1

Organisations of living things

Answer 1

Organisations of cells
Nutrient and gas requirements
Transport

Question 2

How are cells arranged in a multicellular organism?

Answer 2

Differences between unicellular, colonial and multicellular organisms
- structures at the level of the cell and organelle
- relating structure of cells and cell specialisation to function
Structure and function of tissues, organs and systems and relate those functions to cell differentiation and specialisation
Hierarchical structural organisation of organelles, cells, tissues, organs, systems and organisms

Question 3

What is the difference in nutrient and gas requirements between autotrophs and heterotrophs?

Answer 3

Structure of autotrophs through the examination of a variety of materials
- dissected plant materials
- microscopic structures
- range of imaging technologies to determine plant structure
Function of structures in a plant
- tracing the development and movement of the products of photosynthesis
Gas exchange structures in animals and plants through the collection of primary and secondary data and information
- microscopic structures: alveoli in mammals and leaf structure in plants
- macroscopic structures: respiratory systems in a range of animals
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
- photosynthesis
- transpiration-cohesion-tension theory
Digestion of foods in a mammalian digestive system
- physical digestion
- chemical digestion
- absorption of nutrients, minerals and water
- elimination of solid waste
Compare the nutrient and gas requirements of autotrophs and heterotrophs

Question 4

How does the composition of the transport medium change as it moves around an
organism?

Answer 4

Transport systems in animals and plants by comparing structures and components
using physical and digital models
- macroscopic structures in plants and animals
- microscopic samples of blood, the cardiovascular system and plant vascular systems
Exchange of gases between the internal and external environments of plants and animals
Compare the structures and function of transport systems in animals and plants
- vascular systems in plants and animals
- open and closed transport systems in animals
Compare the changes in the composition of the transport medium as it moves around an organism
