What is the function of the mitotic spindle during cell division?
The mitotic spindle is a structure made of microtubules that helps separate chromosomes during cell division. It ensures that each new cell receives the correct number of chromosomes.
At what phase does a spindle develop during cell division?
A spindle develops during the metaphase stage of cell division.
Where do centrioles function in the cell?
Centrioles function in the cell as part of the centrosome, which is involved in organizing the microtubules during cell division. They help in forming the spindle fibers that separate the chromosomes during mitosis and meiosis.
What do spindle fibers do during mitosis and meiosis?
Spindle fibers are responsible for separating and moving the chromosomes during cell division. In mitosis, they help pull sister chromatids apart to opposite poles of the cell, ensuring that each daughter cell receives a complete set of chromosomes. In meiosis, they perform a similar function but with the added complexity of separating homologous chromosomes during the first division and sister chromatids during the second division.
What are centrioles and its function?
Centrioles are cylindrical structures found in animal cells that are involved in organizing microtubules during cell division. They play a crucial role in forming the mitotic spindle, which helps to separate chromosomes during cell division.

During which phase of cell division process are chromosomes attached to the spindle fibers?
Chromosomes are attached to spindle fibers during the metaphase phase of the cell division process.
Cell structures made of individual microtube fibers that are involved in moving chromosomes during cell division are called?
Spindle fibers. These structures form the mitotic spindle and play a crucial role in separating chromosomes during cell division.
What is the relationship between centrosomes and spindle fibers?
Spindle Fibers are formed between centrosomes. Centrosomes migrate to opposite ends of the cell during cell division. The spindle fibers function is to anchor the centrosomes and chromosomes into the poles. The chromosomes then reel them selves in using the spindle fiber.
What anchors the spindle during cell division?
The kinetochore anchors chromosomes to microtubules in the spindle during cell division. The centrosome serves as a nucleating center for microtubules in the spindle and anchors them to opposite sides of the cell.
What structure disappears during telophase?
The structure that disappears during telophase is the mitotic spindle, which is responsible for separating the sister chromatids during cell division. As the cell prepares to complete division, the mitotic spindle breaks down and is no longer needed.
What is the function of the spindle apparatus?
Microtubules
What is the function of kinetochores in cell division?
Kinetochores are protein structures that form on the centromere of chromosomes during cell division. Their main function is to attach to spindle fibers and help separate the chromosomes during mitosis and meiosis. This ensures that each daughter cell receives the correct number of chromosomes.
