Lesson details
Learning outcome
I can describe examples of common diseases in plants, how they spread, and ways to reduce the spread.
Key learning points
- Tobacco mosaic virus is an example of a disease in plants caused by a virus.
- Crown gall disease is an example of a disease in plants caused by a bacterium.
- Barley powdery mildew is an example of a disease in plants caused by a fungus.
- Ways in which plant diseases can be spread, and ways in which the spread can be reduced.
- Impacts of plant diseases, including on biodiversity and human food security.
Keywords
