A) It supports the plasma membrane and is responsible for the particular shape, rigidity, and spatial geometry of each different cell type.
B) It probably plays a role in regulating cell growth and division.

The statement "Its elements are all rigid and permanent structures" is not true. The cytoskeleton is composed of three types of protein fibers: microfilaments, intermediate filaments, and microtubules. These elements are dynamic and can be assembled or disassembled depending on the cell's needs. Therefore, they are not all permanent and can undergo changes in their structure and organization.
