    1. Describe three adaptations that bryophytes have specifically for life on land.
    2. Explain why bryophytes tend to be so small in stature and are often found growing appressed to a surface.
    3. How would you tell the difference between a leafy liverwort and moss? Describe at least two things you could look for.
    4. How would you tell the difference between a thalloid liverwort and hornwort? Describe at least two things you could look for.
    5. Considering what you learned about the cyanobacterium Anabaena’s relationship to the water fern Azolla, how might the Nostoc living inside the hornwort tissues influence the hornwort’s ability to survive on land?
    6. What is the ploidy of the calyptra and where did this tissue come from? Does it have a function?
