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.
What else can I help you with?
What is the name of the structures whose movements are studied in mitosis and meiosis?
Micro-tubules play active role in chromosome movement during cell division.
What is the role of the condensin protein in the process of chromosome condensation 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.
How is the chromosome number halved during cell division: mitosis or meiosis?
The chromosome number is halved during cell division in meiosis, not mitosis.
What structures allow chromosomes to separate and move during 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.
The structure that acts as a scaffolding for chromosomal attachment and movement is called the?
'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.
What is the name of the structures whose movements are studied in mitosis and meiosis?
Micro-tubules play active role in chromosome movement during cell division.
What thin hollow cylinders that assist 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.
What do animal cells have to help with chromosome movement?
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.

A chromosome is made up of even smaller bodies?
It is made up of genes.
Only animal cells have what to help with chromosome movement?
Only animal cells have centrioles, which are cylindrical structures that play a crucial role in organizing the microtubules during cell division. They form the spindle apparatus that helps separate chromosomes and ensure their proper movement to the daughter cells. In contrast, plant cells typically utilize other structures, such as the cell wall and microtubules, to achieve similar functions during mitosis.
Durning cell division what structures do the DNA of eukaryotes bunch into?
During cell division the structures that the DNA of eukaryotes bunch into are the chromosomes.chromosomes
Why is it important for the chromosomes to condense during mitosis a to facilitate DNA replication B to faciliate chromosome movement Cto faciliate cytokinesis d to facilitate spindle formation?
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.
The structure that acts as a scaffolding for chromosomal attachment and movement is called the?
'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.
What two structures seen in the animal cell are composed of microtubules are produced by the centriole?
The two structures in animal cells that are composed of microtubules and produced by the centriole are the spindle fibers and the cilia or flagella. Spindle fibers are essential for chromosome separation during cell division, while cilia and flagella are involved in cell movement and the movement of substances across cell surfaces. Both structures play crucial roles in cellular function and organization.
