Question
Microfilaments
- 3-4 nm
- 3-7 nm
- 20-25 nm
- 13-15 nm
Hint:
Microfilaments are the thinnest fibers of the cytoskeleton.
The correct answer is: 3-7 nm
- The size of the microfilaments ranges between 3 to 7 nm.
- Microfilaments are a type of cytoskeleton that refers to the body responsible for the framework of the cells. It provides shape and structure and also helps in the motility of organelles.
- The cytoskeleton consists of three types, microtubules, intermediate filaments, and microfilaments. Among these, the microtubules are the largest and the thickest, the microfilament are the smallest and the thinnest and the intermediate filament ranges in size in between these other two cytoskeletons.
- The microfilament, being the thinnest and the shortest, ranges in size from 5 to 7 nm. They use their property for easy locomotion. They also help in giving shape to the cells and holding other organelles in right place.
Microtubules are the largest and thickest cytoskeleton. Their size is about 25 nm.
