COMPREHENSIVE QUESTIONS AND
ACCURATE SOLUTIONS
◉ What is a sporophyte?
Answer: The structure in the life cycle that produces spores.
◉ What is a gametophyte?
Answer: The structure in the life cycle that produces gametes.
◉ What does the gametophyte produce?
Answer: Gametes.
◉ What are the two gametes?
Answer: Sperm and egg.
◉ When a sperm fertilizes an egg what is the first cell?
Answer: Zygote.
◉ What does the zygote grow into?
Answer: Sporophyte.
,◉ What does the sporophyte produce?
Answer: Spores.
◉ What do the spores grow into?
Answer: Gametophyte.
◉ What part of the moss is the gametophyte generation?
Answer: The green leafy part.
◉ Where does the sporophyte of the moss grow? What are the two
structures of the sporophyte?
Answer: Grows out of the gametophyte; stalk and capsule.
◉ What part of the fern is the gametophyte generation? What is it
called?
Answer: Heart shaped structure; prothallus.
◉ Where does the sporophyte of the fern grow? Where are the
spores produced on that structure?
Answer: Grows from the prothallus; sori (on the underside of the
leaf).
, ◉ What is the definition of ecology?
Answer: Study of how organisms interact with each other and their
environment.
◉ What are the 4 levels of organization in the study of ecology and
their definitions?
Answer: Population: One species in an area. Community: All
populations in an area. Ecosystem: Populations + abiotic
environment. Biosphere: All ecosystems.
◉ What are the 3 ways to determine population size?
Answer: Direct count, Sampling (extrapolation), Capture-mark-
recapture.
◉ Which counting method is best for each scenario?
Answer: Direct count: small numbers/area. Sampling: uniformly
distributed. Capture-mark-recapture: large areas/moving animals.
◉ What are the assumptions of the capture/recapture method?
Answer: No births/deaths, No immigration/emigration, Marks aren't
lost, Marked animals mix.
◉ What are the three types of population distributions? Which is
most common?
