Examine a variety of plant specimens to understand the effects of pathogens and insects and the responses of plants to disease. Explore the ways plant diseases spread and how an understanding of these processes allows people to control diseases.


Stage 6 Biology


Learning Centre
The Royal Botanic Garden
Mrs Macquaries Road, Sydney


2 hours


$13 per student. Minimum charges apply

Excursion key themes:

  • Examination of infected plant material to observe different types of pathogens and symptoms caused 
  • Defence adaptations of plants, the role of quarantine and strategies used to control plant diseases
  • Symptoms, impacts and disease control strategies for plant diseases.

Students will:

  • Discuss ways that disease affects plants and the impact this can have on ecosystems and human society
  • Investigate the ways diseases are identified and controlled by prevention and treatment strategies
  • Observe a variety of plants affected by diseases and record information about the signs and symptoms
  • Explore the steps used in the quarantine process and examples of diseases controlled by these methods
  • Research plant diseases considered a threat to ecosystems or agricultural trade.

Plant diseases were particularly well done – excellent samples… educator’s knowledge was brilliant.

4 The Search for Better Health

  1. What is a healthy organism?
  • discuss the difficulties of defining the terms ‘health’ and ‘disease’
  1. Over 3000 years ago the Chinese and Hebrews were advocating cleanliness in food, water and personal hygiene
  • identify the conditions under which an organism is described as a pathogen
  1. During the second half of the nineteenth century, the work of Pasteur and Koch and other scientists stimulated the search for microbes as causes of disease
  • distinguish between viruses, bacteriaprotozoansfungi and macro-parasites and name one example of a disease caused by each type of pathogen
  • identify data sources, gather process and analyse information from secondary sources to describe one named infectious disease in terms of its cause, transmission, host response, major symptoms, treatment, prevention and control

7. Increased understanding has led to the development of a wide range of strategies to      

    prevent and control disease

  • discuss the role of quarantine in preventing the spread of disease and plants and animals into Australia or across regions of Australia
  • explain how one of the following strategies has controlled and/or prevented disease:
  • public health programs
  • pesticides
  • genetic engineering to produce disease-resistant plants and animals
  • perform an investigation to examine plant shoots and leaves and gather first-hand information of evidence of pathogens and insect pests
  • process and analyse information from secondary sources to evaluate the effectiveness of quarantine in preventing the spread of plant and animal disease into Australia or across regions of Australia
  • gather and process information and use available evidence to discuss the changing methods of dealing with plant and animal diseases, including the shift in emphasis from treatment and control to management or prevention of disease
