Question
Choose the correct statement from the following.
- Microfilaments are made of actin
- Microtubules are made up of tubulin
- Intermediate filaments are resistant to cytochalasin-B and colchicine
- All of these
Hint:
The three different types of cytoskeletons perform specific functions.
The correct answer is: All of these
- All of the given statements are correct.
- The cytoplasm consists of a network that ensures the accurate framework of the cell. This is known as the cytoskeleton. This cytoskeleton is of three types, microtubules, microfilaments, and intermediate filaments.
- The microtubules are the thickest and largest of them all. They are composed of tubulin protein. They make sure that the organelles are in the right position and they also form a channel through which transportation takes place.
- The microfilament is the shortest and thinnest of them all. It is usually found in contractions of muscles as it is composed of the actin filament. It helps in muscle movement and can also change its shape easily.
- The intermediate filament is the one whose size is between the other two filaments. It holds the microtubules and microfilaments together. Intermediate filaments are known to be resistant to cytochalasin-B and colchicine.
The three types of cytoskeletons differ in shape, size, protein, and function.
