Question
Chapter 14.7, Problem 2MC
Summary Introduction
To determine:
The connection between extrafloral nectaries and rapid
Concept introduction:
Extrafloral nectaries is a liquid rich in sugar called nectar produced by plants in the glands called nectaries within the flower, which attracts pollinating animals. Speciation in plants means forming new distinct species in the course of evolution.

What is the evolutionary advantage for a flowering plant to be pollinated with pollen from a different individual plant (of the same species)?
Considering the trends in floral evolution, how do you think these changes contribute in ensuring successful sexual reproduction among angiosperms? Cite at least two (2) examples of plants exhibiting advanced floral features to support your answer.
Most flowers contain both male and female reproductive structures, in contrast to the cones of gymnosperms, which are either male or female. Explain how bisexual flowers might be an advantageous evolutionaryadaptation to the flowering plants that possess them.

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.arrow_forwardA slight change in a plant species’ flower structure might favor a different pollinator. How might such a change in flower structure lead to a new plant species? How does coevolution between flowering plants and animal pollinators help explain the huge diversity of angiosperms?arrow_forward
- What is the evolutionary significance of pollen and seeds?arrow_forwardIf animal pollination has so many advantages,why did approximately 20% of angiosperm species subsequently evolve a dependence on wind for pollination?arrow_forwardGenerally, immature fruits are green in color, and they change tobright, attractive colors when they become ripe.

- a. How are the angiosperms classified according to the Angiosperm Phylogeny Group (APG)? b. What is the present understanding about the origin of flowering plants, and the classification of angiosperms into “monocots” and “dicots”, based on most recent evidences? c. The work of plant taxonomists of the 20th century who identified /established the different families of flowering plants based mainly on morphological and anatomical details is still valued and being used today, despite the general acceptance of the Angiosperm Phylogeny Group (APG) as a classification system for the flowering plants. Explain why.arrow_forwardFor 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.arrow_forwardImagine 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 possiblearrow_forward
