Watermelon plants have male and female flowers on the same plant. The picture below shows a male flower and a female flower (bottom).

Short(er) question #2 The first vascular plants to evolve had sporophyte and gametophyte generations that resembled one another. This meant that both the sporophyte and the gametophyte had vascular tissue (xylem tracheids, phloem).  Seedless vascular plants now (mostly) have much simpler gametophyte generations which lack vascular tissue. Why is a lineage with a simpler gametophyte generation more evolutionarily successful? (maximum 3-4 sentences)

Figure B Is this flower made up mostly of sporophyte or gametophyte tissue?

Figure B Directly inside of which structure will microspores be made?

B. Your classmate tells you she thinks a watermelon is a berry. Do you agree or disagree? Explain why. (maximum 2-3 sentences) 

A yellow discoloration of the skin due to a buildup of bile.

Epidermis:

Figure B Directly inside of which structure will microspores be made?

Figure B Which structure on the fern below is homologous to structures B and C on the flower?

Example #3 chosen: Which group of plants did the trait first evolve in, and how does this trait contribute to the trend?
