  • What is the predominant class of receptor kinases in plants?
    Serine/Threonine Kinases are the predominant class of receptor kinases in plants.
  • Which class of receptor kinases is most common in animals?
    Tyrosine Kinases are the most common class of receptor kinases in animals.
  • Do plants have homologs for the JAK-STAT signaling pathway?
    No, plants do not have homologs for the JAK-STAT signaling pathway.
  • Name two key plant-specific signaling molecules mentioned in the lesson.
    Auxins and ethylene are two key plant-specific signaling molecules.
  • What is the main function of auxins in plants?
    Auxins stimulate plant growth.
  • What process does ethylene promote in plants?
    Ethylene promotes fruit ripening in plants.
  • Are Notch, Wnt, and Hedgehog signaling pathways found in plants?
    No, Notch, Wnt, and Hedgehog signaling pathways are not found in plants.
  • What are some plant signaling molecules involved in besides growth and ripening?
    They are involved in stem elongation, cell division, dormancy, and light sensing.
  • Why is signaling in plants discussed separately from animals?
    Because signaling mechanisms evolved differently in plants compared to animals.
  • Do plants have receptor kinases similar to animals?
    Yes, plants have receptor kinases similar to animals, but the predominant type differs.
  • Are the signaling molecules for stem elongation and light sensing found in animals?
    No, these signaling molecules are specific to plants and not found in animals.
  • What is a major difference between plant and animal signaling pathways?
    Plants lack several key animal signaling pathways and have unique signaling molecules.
  • What is the importance of light sensing in plant signaling?
    Light sensing is crucial for plant functions and is regulated by specific signaling molecules.
  • Are cell dormancy and division regulated by plant-specific signaling molecules?
    Yes, plant-specific signaling molecules regulate cell dormancy and division.
  • Why might advanced biology students need to learn about Notch, Wnt, and Hedgehog pathways?
    Because these are important animal signaling pathways, but they are not present in plants.
