Question

what is the function of intermediate filaments? a cell-to-cell junctions b cell movement c form flagella d cell shape

Explanation:

To determine the function of intermediate filaments, we analyze each option:

• Option A: Cell - to - cell junctions are mainly formed by structures like desmosomes (which can involve intermediate filaments but that's not their primary function). The primary function of intermediate filaments is not cell - to - cell junctions.
• Option B: Cell movement is mainly associated with microfilaments (like actin filaments) and microtubules in some cases (like in cilia and flagella movement), not intermediate filaments.
• Option C: Flagella are formed by microtubules (in a 9 + 2 arrangement), not intermediate filaments.
• Option D: Intermediate filaments are a component of the cytoskeleton. One of their main functions is to provide structural support to the cell, which helps in maintaining the cell shape.

Answer:

D. Cell shape
