The 20 questions

  1. What term describes a directional growth response of a plant to a stimulus?

    • Reflex
    • Tropism
    • Kinesis
    • Taxis

  2. What term describes a directional movement of a motile organism towards a stimulus?

    • Tropism
    • Kinesis
    • Taxis
    • Reflex

  3. What term describes a non-directional movement response involving changes in speed or turning rate?

    • Tropism
    • Kinesis
    • Taxis
    • Reflex

  4. Which plant hormone-like substance is involved in the response of shoots to light?

    • Insulin
    • Acetylcholine
    • Adrenaline
    • Indoleacetic acid (IAA)

  5. What is the main function of a simple reflex arc in animals?

    • Rapid protective response
    • Conscious decision making
    • Learned behavioural adaptation
    • Increased muscle mass

  6. Which neurone connects sensory and motor neurones in a simple reflex arc?

    • Effector neurone
    • Receptor neurone
    • Myelinated neurone
    • Relay neurone

  7. What effect does high IAA concentration have on cell growth in plant shoots?

    • Promotes cell elongation
    • Inhibits cell elongation
    • Stimulates cell division
    • Promotes cell lysis

  8. A woodlouse moves faster and turns more often in dry air than in humid air. What type of response is this?

    • Tropism
    • Reflex
    • Kinesis
    • Taxis

  9. A maggot moves towards a light source. What is this response?

    • Chemotropism
    • Kinesis
    • Positive phototaxis
    • Negative geotropism

  10. What is the best dependent variable for measuring woodlouse taxic response?

    • Total movement speed
    • Respiratory rate
    • Woodlice per compartment
    • Total distance travelled

  11. A woodlouse investigation shows it moves 12 cm per minute in dry conditions and 4 cm per minute in damp conditions. How many times faster is it moving in dry conditions?

    • 4 times
    • 1/3 times
    • 8 times
    • 3 times

  12. How does high IAA concentration affect cell growth in plant roots?

    • Inhibits cell elongation
    • Promotes cell elongation
    • Stimulates cell division
    • Accelerates cell division

  13. Which term describes a directional movement towards or away from a stimulus?

    • Reflex
    • Kinesis
    • Taxis
    • Tropism

  14. What type of response is shown when a plant shoot bends towards unilateral light?

    • Positive phototropism
    • Negative gravitropism
    • Positive gravitropism
    • Negative phototropism

  15. What is the primary survival advantage of taxes and kineses to mobile organisms?

    • Faster reproduction rate
    • Increased mutation rate
    • Predator direct avoidance
    • Favourable conditions retention

  16. Why do simple reflex arcs produce extremely rapid protective responses?

    • Bypasses conscious control
    • Requires brain processing
    • Lacks sensory neurones
    • Uses hormonal transmission

  17. What primary benefit does positive phototropism provide to a plant shoot?

    • Maximises light absorption
    • Increases mineral uptake
    • Prevents fungal infection
    • Reduces water loss

  18. Which feature distinguishes a kinesis response from a taxis response?

    • Irreversible growth
    • Non-directional movement
    • Directional movement
    • Hormonal control

  19. Which plant hormone redistributes to the shaded side of a shoot during phototropism?

    • Abscisic acid
    • Gibberellin
    • Ethene
    • IAA

  20. How does a high concentration of IAA affect cell elongation in plant shoots?

    • Inhibits cell elongation
    • Increases cell elongation
    • Causes cell lysis
    • Prevents cell division
