We have talked about many plant structures, roots, stems, reproductive structures - and leaves. Leaves are essential for plants because they are the site of photosynthesis and food production. But there is always a tension between photosynthesis and water loss versus preventing water loss. How do the structures and tissues of the leaves of Gymnosperms and Angiosperms differ? (Remember there are more than one type of Angiosperm leaf). How are they similar? How do the structures and adaption of leaves reflect the environments that Gymnosperms and Angiosperms are adapted to?

Lesson 13: Grass-roots Effort at Changing Culture Discussion In this lesson, we talked about organizations and their culture. We often think that culture is created at the top, like Howard Schulz creating Starbuck's culture. Discuss how you might change your organization’s culture as a grass-roots effort, or starting at the bottom of the firm to create change?

Plant reproductive strategies and structures are characteristics use to classify the major plant groups. Angiosperms developed most recently in plant evolution but show the greatest diversity in the number of species, structures, and enviromnental adaptations in spite of being in existence the shortest amount of time. What is an advantage the flower brings to success of this group of plants?

In the discussion for fatigue up to this point we have talked about the damaging effect of the number of cycles of loading but we have not discussed about frequency (i.e. how often these loading cycles occur). Which class of materials do you think might be sensitive to the frequency of loading? Provide two physical mechanisms that may affect fatigue life (at least indirectly).

Describe the difference between discounting and interest, referring to the way we have talked about it in class. Specifically use this example: A company is looking to purchase an item worth 10k today. The same item can be purchased 3 years later for 10k. Why is the second option more desirable, and how much more desirable is it if your cost of capital is 5%?

We have talked in class about second order differential equations. These equations often arise in applicationsof Newtons second law of motion. For example, supposeyis the displacement of a moving object with massm. Its reasonable to think of two types of time-independent forces acting on the object. One type - suchas gravity - depends only on positiony. The second type - such as atmospheric resistance or friction -may depend on position and velocityy′. (Forces that depend on velocity are called damping...
