Question

Which of the following have the ability to disassemble and reform quickly?

a. microfilaments and intermediate filaments

b. microfilaments and microtubules

c. intermediate filaments and microtubules

d. only intermediate filaments

Short answer

Microfilaments and microtubules has the ability to disassemble and reform quickly.

Step-by-step solution

Explanation

Microfilament has the ability to disassemble and reform quickly but intermediate filament does not have that as it helps in maintaining the shape of cells. So, option a is incorrect.

Microtubules can disassemble and form quickly but intermediate filament can not. Hence wrong combination. Option c is wrong too.

The intermediate filament can not disassemble and reform quickly. This option is wrong as well.

Microfilaments, as well as microtubules, can reform and disassemble quickly and help cells to change their shape and move i.e. it provides flexibility to the cell. Thus, option b is correct.

Conclusion

Only Microtubules and Microfilaments have the ability to change their shape quickly hence aids in cell movement.
