Lesson Title: Today we are learning about
How do plants defend themselves from pathogens?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Plants can be infected by a range of viral, bacterial and fungal pathogens as well as by insects.
  2. Plants can be damaged by a range of ion deficiency conditions. Knowledge of ions is limited to nitrate ions needed for protein synthesis and therefore growth, and magnesium ions needed to make chlorophyll. * The understanding of ion deficiencies allows horticulturists to provide optimum conditions for plants.
  3. Stunted growth caused by nitrate deficiency
  4. Chlorosis caused by magnesium deficiency
  5. Students should be able to describe physical and chemical plant defence responses.
  6. Physical defence responses to resist invasion of microorganisms. ? Cellulose cell walls. ? Tough waxy cuticle on leaves. ? Layers of dead cells around stems (bark on trees) which fall off.
  7. Chemical plant defence responses. ? Antibacterial chemicals. ? Poisons to deter herbivores.
  8. (HT only) Plant diseases can be detected by: ? stunted growth ? spots on leaves ? areas of decay (rot) ? growths ? malformed stems or leaves ? discolouration ? the presence of pests.
  9. (HT only) Identification can be made by: ? reference to a gardening manual or website ? taking infected plants to a laboratory to identify the pathogen ? using testing kits that contain monoclonal antibodies.
  10. Mechanical adaptations. ? Thorns and hairs deter animals. ? Leaves which droop or curl when touched. ? Mimicry to trick animals.
Think about how you can match the needs of ALL students
Keywords:
  • Discoloration: loss of colour in tissues (1)
  • malformed: incorrectly shaped stems (1)
  • decay: rotting of tissues (1)
  • Stunted growth: limited growth (1)

AFL/Key Questions:
  1. (Bio only) What can cause plant infections?
    Plants can be infected by a range of viral, bacterial and fungal pathogens as well as by insects.
  2. (Bio only) What causes deficiency conditions in plants?
    Deficiency conditions in plants can be caused by a lack of ions
  3. (Bio only) What ion can cause stunted growth and why?
    Stunted growth is caused by nitrate deficiency, this is caused by reduced protein synthesis.
  4. (Bio only) What ion can cause chlorosis (pale green leaves)?
    Chlorosis is caused by magnesium deficiency
  5. (Bio only) What are the chemical and physical plant defence responses.
    Physical-Thorns Chemical-Toxins produced example stinging nettle.Some plants are poisionous.
  6. (Bio only) What are the physical defences that plants have to resist invasion of microorganisms?
    The physical defence responses to resist invasion of microorganisms include: ? Cellulose cell walls. ? Tough waxy cuticle on leaves. ? Layers of dead cells around stems (bark on trees) which fall off.
  7. (Bio only) What are the chemical defences that plants have to resist invasion of microorganisms?
    The chemical plant defence responses to resist invasion of microorganisms include: - Antibacterial chemicals. - Poisons to deter herbivores.
  8. (Bio only) What are the different ways that plant diseases can be detected?
    (HT) Plant diseases can be detected by: - stunted growth - spots on leaves - areas of decay (rot) - growths - malformed stems or leaves - discolouration - the presence of pests.
  9. (Bio only) How can plant diseases be identified? (give three ways)
    (HT) Plant diseases can be identified by: - reference to a gardening manual or website - taking infected plants to a laboratory to identify the pathogen - using testing kits that contain monoclonal antibodies.
  10. (Bio only) What are the mechanical adaptations that plants have to resist invasion of microoganisms?
    The mechnical adaptations that plants have to resist invasion of microorganisms are: - Thorns and hairs deter animals. - Leaves which droop or curl when touched. - Mimicry to trick animals.

Differentiation: AGT, SEND, LLL, Disadvantaged
Remember to check for PROGRESS
Starter Activity Differentiation and Challenge question/task
  • Students to copy and complete the keywords.
  • Teacher reveals missing letters; Students correct mistakes;
  • Discuss the scientific meanings of the words.
  • Students to write down the definitions of the most important / new keywords.
  • Discuss the 'Memory Anchor'.
    • What does it show?
    • How does it relate to the what we are learning about today (title)?
Think about PACE – Develop, consolidate and deepen knowledge, skills and understanding
