Introduction:
Angiosperms are flowering plants in which flowers contain the organs required for sexual reproduction that is an evolutionary adaptive change to enhance reproductive success. Flowers contain organs for sexual reproduction, which includes carpels, stamens, sepals, and petals. Female gametophyte forms in the carpel present in the center of the flower and male gametophyte forms in the stamens, which surrounds the carpel.

For those who aren't scientists, there is disappointment when it's learned that scientists don't have all the answers to our questions. (Personally, it took awhile for me to be comfortable with this, and now I love it!). After reading the links and article, what are at least five unanswered questions that pertain to angiosperm evolution and diversification.
Imagine that you are a member of a research group conducting research on fruit type and seed dispersal. Your group has submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document.
Why is seed dispersal important in the life of plants? What would be the consequences of having seeds that simply fell to the ground underneath the parent tree?
Please be detailed as possible
Question #1.
Identify the economic uses of at least 3 species in each order (Laurales, Magnoliales and Piperales).
Question #2.
What are the common features among the three orders under the paleodicots? Why are they presumed to be the first angiosperms?
Question #3.
Describe the orders under the paleodicots (Laurales, Magnoliales and Piperales) in terms of plant habit, reproductive type (monoecius/dioecius), leaf type, leaf shape, floral characteristics, fruit morphology, seed size/shape, and other distinct feature.
