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.

Students have asked these similar questions
1 a) Describe the process of double-fertilization in this fireweed. b) What is the significance of this process in plant evolution?
Clausen and colleagues proposed two hypotheses to explainthis variation within a species: (1) There are genetic differencesbetween populations of plants found at different elevations.(2) The species has developmental flexibility and can assumetall or short growth forms, depending on local abiotic factors.If you had seeds from yarrow plants found at low and highelevations, how would you test these hypotheses?
A) Using the information/image provided, why could the researchers rule out pollinator selection as a reason for flower color variation?
B) What must be true about the flowers in Boechera stricta?
A) Plants have both male and female flowers that are reproductively mature at the same time.
B) Plants have both male and female flowers that are reproductively mature at different times.
C) Plants produce either male or female flowers
C) If the scientists' hypothesis is true, what type of herbivore defense is flower pigmentation in this mustard?
either constitutive or inducible

However, if the plant has not been pollinated previously, self-pollination can occur. However, if cross pollination occurs after self-pollination takes place, the pollen from cross pollination reaches the style before the pollen from self-pollination. Using course concepts and vocabulary 1) Provide a reasoning for this phenomenon. 2) Would this adaptation for reproduction be beneficial for the plant?arrow_forward
- Based on this evidence, is it likely that burdock would reproduce as much if it didn’t have specially structured seeds? (a) it is most likely that it would still reproduce, but the offspring would probably be located much closer together (b) there is not enough information to speculate about how well burdock plants reproduce (c) no, there wouldn’t be as much burdock without its special structures (d) Yes, burdock would spread just as well regardless of the design of its seed podsarrow_forwardImagine that you are a member of a research group conducting research on fruit type and seed dispersal.

These plants spread over the surface of moist groun and have numerous small stems that have tiny leaflets. They have root-like structures but do NOT have roots. Back at the lab, tests indicate that the majority of the plant material is haploid.
