    Cells can be described as having a cytoskeleton of internal structures that contribute to theshape, organization, and movement of the cell. Which of the following are part of thecytoskeleton?

    A) the nuclear envelope

    B) mitochondria

    C) microfilaments

    D) lysosomes

    E) nucleoli



    A) the nuclear envelope


    (someone had "A" as the previous answer but "C" definitely makes more sense.) I set it back to A because this question is on Course Compass and it shows the correct answer as A) the nuclear envelope. Since Course Compass is set up by the book publisher I assume that to be the correct answer.

    Microfilaments are apart of the cytoskeleton which participate in movement. A is incorrect because it's funtion is to encase cromatin/ Chromosomes. C. Is the Best answer.

    Centrioles, cilia, flagella, and basal bodies have remarkably similar structural elements andarrangements. This leads us to which of the following as a probable hypothesis?

    A) Disruption of one of these types of structure should necessarily disrupt each of the others as

    well.

    B) Loss of basal bodies should lead to loss of all cilia, flagella, and centrioles.

    C) Motor proteins such as dynein must have evolved before any of these four kinds of structure.

    D) Evolution of motility, of cells or of parts of cells, must have occurred only once.

    E) Natural selection for motility must select for microtubular arrays in circular patterns.

    E) Natural selection for motility must select for microtubular arrays in circular pattern

    Which of the following statements about the cytoskeleton is true?

    A) The dynamic aspect of cytoskeletal function is made possible by the assembly anddisassembly of a large number of complex proteins into larger aggregates.

    B) Microfilaments are structurally rigid and resist compression, while microtubules resist tension(stretching).

    C) Movement of cilia and flagella is the result of motor proteins causingmicrotubules to moverelative to each other.

    D) Chemicals that block the assembly of the cytoskeleton would cause little effect on the cell'smetabolism

    E) Transport vesicles among the membranes of the endomembrane system produce thecytoskeleton.

    C) Movement of cilia and flagella is the result of motor proteins causingmicrotubules to move relative to each other.
