Question
Chapter 38.1, Problem 3CC
Summary Introduction
To explain: Evolution of long styles in most of the flowering plants.
Concept introduction: Style is a long, slender stalk found within the flower that connects the stigma and ovary. Stigma is a sticky platform at the top of the style where pollen are deposited and ovary is present at the bottom of stigma which contains the egg cells and support the cells that is required for reproduction.

Students have asked these similar questions
WHAT IF? If a seed could not enter dormancy, howmight that affect the embryo’s transport or survival?
And some plants as stigma becomes receptive to Polin able to facilitate a pollen tube at a different time from when the anthers ripen. How would this affect the plant reproductive strategy why would this increase diversity in the plants offspring?
MAKE CONNECTIONS In somepea plant crosses, the plants areself-pollinated. Is self-pollinationconsidered asexual or sexualreproduction? Explain.(See Concept 13.1.)

Which one is the most protected from the external environment? Which trend(s) in plant evolution does your work on this question bring to mind?arrow_forwardThe drooping, bell-like flower Aquilegia canadensis is adapted for cross-pollination. 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

- INTERPRET DATA Flower parts are arranged in four concentric circles: sepals, petals, stamens, and carpel. According to the ABC model of floral organ development in Arabidopsis, class A genes are needed to specify sepals, the A and B genes to specify petals, the B and C genes to specify stamens, and class C genes to specify the carpel.
