Keywords:

  • Vector: Something that carry's disease (1)
  • Aphids: Aphids are small sap-sucking insects (1)
  • Black Spot Disease: the most serious disease of roses. It is caused by a fungus (1)

Knowledge of plant diseases is restricted to tobacco mosaic virus as a viral disease, black spot as a fungal disease and aphids as insects. What are three examples of plant diseases you need to know?

show students a range of photos of the affected plants and ask them which photo matches to t

The pathogens that cause malaria are protists. What are the pathogens that cause malaria called?

Show students a image of a protist and ask them describe if it is more like an animal or plant cell. Show them the video after: https://www.bbc.com/education/clips/z2tq2hv

Rose black spot is a fungal disease where purple or black spots develop on leaves, which often turn yellow and drop early. It affects the growth of the plant as photosynthesis is reduced. What is rose black spot and how does it affect the growth of a plant?

Students use a note maker document (A4 or A3 page split into 4/6/8 boxes) to take notes on information from different stations on the various plant diseases. Answering questions about each one.

Rose black spot is spread in the environment by water or wind. How is rose black spot spread in the environment?

EW: Make a script for a video segment for ‘Gardeners’ World’ on plant diseases – how to recognise them and why they harm your plants. (could video if time allows) HT: Use ICT to include images etc. or make ‘model’ infected/healthy leaves to show.

Rose black spot can be treated by using fungicides and/or removing and destroying the affected leaves. How can rose black spot be treated?

GF: Justify why there is a large part of the scientific industry dedicated to the prevention and development of cures for plant diseases?

The malarial protist has a life cycle that includes the mosquito. Malaria causes recurrent episodes of fever and can be fatal. What vector is used to spread malaria and what are the symptoms of it?

GF: What is the economic impact of plant diseases on the agricultural community?

The spread of malaria is controlled by preventing the vectors, mosquitos, from breeding and by using mosquito nets to avoid being bitten. How is the spread of malaria controlled?

Ask students to download a free app for stop time animation and bring devices in for the next lesson
