Understanding the Cytoskeleton

This video from Moomoomath and Science discusses the cytoskeleton, a network of filaments in cells that provides structural support, facilitates movement of vesicles, assists in chromosome separation during mitosis, and aids in cell movement. The cytoskeleton is composed of three types of fibers: microfilaments, intermediate filaments, and microtubules, each with specific roles. The video concludes with a reminder of the importance of the cytoskeleton and encourages viewers to subscribe for more educational content.

What is the primary function of the cytoskeleton in a cell?

• To synthesize proteins

• To produce energy

• To provide structural support and facilitate movement

• To store genetic information

Which type of cytoskeleton fiber is the narrowest?

• Microtubules

• Intermediate filaments

• Microfilaments

• Actin filaments

What is the role of intermediate filaments in the cell?

• To transport vesicles

• To generate energy

• To maintain cell shape

• To assist in cell division

Which cytoskeleton fiber helps in pulling chromosomes apart during mitosis?

• Microfilaments

• Actin filaments

• Intermediate filaments

• Microtubules

How do microtubules contribute to cell movement?

• By forming the cell membrane

• By creating flagella or cilia

• By synthesizing proteins

• By storing nutrients
