Are centrioles vestigial structure?
Centrioles are not considered vestigial structures as they play important roles in cell division, organizing the mitotic spindle during cell division, and forming the basal bodies of cilia and flagella. They are essential for various cellular processes in animal cells.
Is spindle a organ in cell?
No, a spindle is a structure formed during cell division (mitosis) to help separate chromosomes. It is not an organ, but rather a network of microtubules that helps move and segregate chromosomes during cell division.
A fanlike microtubule structure that helps separate the chromosomes is a?
mitotic spindle. It is composed of microtubules and plays a crucial role in ensuring the accurate distribution of chromosomes during cell division.
What is the structure for spindle fibers?
Spindle fibers are formed from microtubules, which are made up of tubulin protein subunits. They form a structure known as the mitotic spindle, which helps to separate chromosomes during cell division. The spindle fibers attach to chromosomes at specialized protein structures called kinetochores.
What is a tiny microtubule structure located in the cytoplasmthat helps create the spindle fibers called?
The tiny microtubule structure located in the cytoplasm that helps create the spindle fibers is called a centriole. Centrioles are responsible for organizing the microtubules into the spindle apparatus during cell division.
What form a spindle shape structure of protein fibres on which the chromosomes move durung nuclear division?
The spindle shape structure of protein fibers that chromosomes move on during nuclear division is called the mitotic spindle. This structure is made up of microtubules that are responsible for segregating the chromosomes into the daughter cells during cell division.
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 are the short stringy structure that appears just before cell division?
Spindle Fibres.
Are centrioles vestigial structure?
Centrioles are not considered vestigial structures as they play important roles in cell division, organizing the mitotic spindle during cell division, and forming the basal bodies of cilia and flagella. They are essential for various cellular processes in animal cells.
Cellular structure to which the chromosomes attach?
Centromere. It is a region on a chromosome where the kinetochore forms, allowing for attachment to spindle fibers during cell division, ensuring proper segregation of chromosomes.
What fibrous cellular structure disappears from the screen just as the cell leaves anaphase and progresses into telophase?
spindle

What is the cytoskeletal structure that pulls chromosome apart?
The cytoskeletal structure responsible for pulling chromosomes apart during cell division is the spindle apparatus. It consists of microtubules that attach to the chromosomes and exert forces to separate them into two daughter cells. The spindle apparatus is essential for ensuring the accurate distribution of genetic material during cell division.
What structure is most closely associated with the production of the mitotic spindle?
The centrosome is most closely associated with the production of the mitotic spindle. It is responsible for organizing the microtubules that make up the spindle fibers during cell division.
