Quick explanation
Describe physical plant defence responses
- This point belongs to Plant disease (biology only), especially Plant defence responses.
- You need to be able to describe physical plant defence responses.
- The key ideas to know are responses, defence, and plant.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Plant defence responses to exam-style questions, flashcards, and revision notes for Plant disease (biology only).
Quick student answer
How does physical plant defence responses work?
Direct answer
In Biology, this page helps you answer questions about physical plant defence responses within Plant disease (biology only). Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are physical plant defence responses and cellulose cell walls.
Key terms
- physical plant defence responses: The structural features of plants, such as thorns, waxy cuticles, and layers of dead cells, that protect against herbivores and pathogens.
- cellulose cell walls: The rigid outer layer of plant cells that provides structural support and helps resist invasion by microorganisms.
Common trap
Misunderstanding Physical Defences: Focus on specific examples of physical defences, such as the structure and function of thorns, waxy cuticles, and layers of dead cells, to clearly distinguish them from chemical responses.
