The microfilaments are two twisted strands of proteins (actins) 7nm in diameter and can be up to several centimeters long. They are responsible for the movement of pseudopodia, the prey that is engulfed by Amoebae.
The intermediate filaments is composed of eight microfilaments bound to form a rope like structure. It's function is to maintain cells shape by holding all the different parts of the cell in an advanced web.
The microtubules are tubes consisting of two proteins (tubulins). They control the movement of chromosomes during cell division, the movement of organelles within cytoplasm, and the movement of cilia and flagella.
So short answer is- Microtubules.
Micro-tubules play active role in chromosome movement during cell division.
Condensin proteins play a crucial role in chromosome condensation during cell division by helping to compact and organize the DNA into tightly coiled structures. This condensation process ensures that the chromosomes are properly segregated and distributed to daughter cells during cell division.
The chromosome number is halved during cell division in meiosis, not mitosis.
The spindle apparatus, made up of microtubules, plays a key role in chromosome separation and movement during mitosis. The centrosomes help organize and control the spindle apparatus. The kinetochores, located at the centromere of each chromosome, attach to the microtubules and facilitate chromosome movement.
'kinetochore.' It is a complex protein structure that forms on the centromere region of the chromosome and is responsible for attaching the chromosome to microtubules during cell division, allowing for proper alignment and segregation of chromosomes.
Micro-tubules play active role in chromosome movement during cell division.
Spindle fibers are thin hollow cylinders that assist in chromosome movement during cell division. These structures are made of microtubules and help separate the chromosomes, ensuring that each daughter cell receives the correct number of chromosomes.
Animal cells have structures called centrioles that help in chromosome movement during cell division. These centrioles form the spindle fibers that attach to the chromosomes and help to segregate them into the daughter cells. Additionally, motor proteins like dynein and kinesin also play a role in chromosome movement within the cell.

It is made up of genes.
During cell division the structures that the DNA of eukaryotes bunch into are the chromosomes.chromosomes
B. It is important for chromosomes to condense during mitosis to facilitate chromosome movement. Condensed chromosomes are easier to separate and move to opposite ends of the cell during cell division, ensuring that each daughter cell receives the correct number of chromosomes.

Centrioles give rise to spindle fibers that help with chromosome movement during cell division. They are important for organizing and separating chromosomes during mitosis and meiosis.
The failure of chromosome pairs to separate properly during cell division.
