Question

question
which statement about the cytoskeleton is true?
answer
intermediate filaments are hollow tubes of protein that provide structural support.
plant cells lack a cytoskeleton because they have a rigid cell wall.
components of the cytoskeleton often mediate the movement of organelles within the cytoplasm.
microtubules are chains of proteins that resist stretching.
microfilaments are more permanent structures in cells compared to intermediate filaments and microtubules.
i dont know yet

Explanation:

Intermediate filaments are not hollow tubes. Plant cells have a cytoskeleton despite having a cell - wall. Microtubules are hollow cylinders, not chains that resist stretching. Microfilaments are less permanent than intermediate filaments. Components of the cytoskeleton, such as microtubules and microfilaments, can help move organelles within the cytoplasm.

Answer:

Components of the cytoskeleton often mediate the movement of organelles within the cytoplasm.
