Tubules, microtubules
|
|
|
Spindle fibers, microfilaments

Explanation:
Detailed explanation-1: -In cilia and flagella, the microtubules are organized as a circle of nine double microtubules on the outside and two microtubules in the center. The centrosome is a region near the nucleus of animal cells that functions as a microtubule-organizing center.
Detailed explanation-2: -The main difference between microtubules and microfilaments is the proteins they are made of. Microtubules are made of tubulin and microfilaments are made of actin. Microtubules are also quite large compared to microfilaments. Although both provide structure and support to the cell, they also have different roles.
