Problem: Please explain the questions thoroughly
Q1. How would a biologist identify a sporophyte in the fossil record (what features tend to preserve well)
Q2. How could you visibly distinguish a sporophyte from a gametophyte? In general, what features would you look for?
Q3. Are all leaves homologous in plants? Explain your answer
Q4. Explain how the leaves of the Monilophytes differ. Are the leaves homologous? What happened to result in the differences we observe today?
Q5. How does pollen help expand the range of seed plants? How did earlier-evolved plants perform the functions of pollen grains, and how did that restrict the range of earlier-evolved plants?
Q6. How do ovules benefit seed plants compared to the megaspores produced by Selaginella?
Consider the source of nutrition and timing of dispersal in your answer.
Q7. Explain what happens during fertilization in gymnosperms and angiosperms, in what ways are the products similar, and in what ways are they different?
