Question
Chapter 29, Problem 12RQ
Summary Introduction
To explain: The way in which 9+2 arrangement of microtubules produces a bending motion.
Introduction: A crucial characteristic of animals is movement. Animal movement takes place in various forms in animal tissues, for example, the movement of skeletal muscles. However, most animal movements are based on a single fundamental mechanism such as contractile proteins.
Summary Introduction
To differentiate: Cilia and flagella.

During the movement of a cilium or flagellum, describe the type of movements that occur between the motor proteins and microtubules
Intermediate filaments have identical ends and lack polarity, whereas
microtubules have two distinct ends with defined polarity. What is the molecular cause of these differences?
Please keep brief - 2 sentences/dot points max.
if you visualize the cytoskeleton of a cell that is expanding in one direction, you typically observed a strong orientation of the cytoskeleton. Please answer the following three questions.
a. Would the cytoskeleton be oriented parallel or perpendicular to the direction of cell expansion?
b. Would the cellulose fibers in the cell wall be parallel or perpendicular to the cytoskeleton?
c. Explain why cytoskeleton, cellulose fibers, and direction of cell expansion have the relationship mentioned in a and b?
