CHAPTER 7: TRANSPORT IN MULTICELLULAR PLANTS
This chapter was important in that it described how plants transport materials throughout their systems. A real world application of this knowledge would be that farmers need to understand how their crops grow and function so that way they can nourish them in the best ways possible. I see the real world application, and I hope that others do now, too.
On the quiz I got confused as to what vessel elements and companion cells were. Vessel elements are cells that are involved with the transport of water. They work with xylem to move water throughout plants. Companion cells on the other hand are cells with unthickened cellulose walls and dense cytoplasm that are found in close association with phloem sieve elements to which they are directly linked via many plasmodesmata.
On the test, I forgot to mention a very important difference in my answer to number 5. Xylem is a dead empty tube with lignified walls, through which water is transported in plants. It is formed by xylem vessel elements lined up end to end. Phloem, however, is the living tissue in plants that move sucrose and other assimilates downwards from the leaves to the rest of the plant.
Other than these two minor errors in this chapter, I think that my quiz and test answers provide adequate evidence that I have mastered this chapter.
