What else can I help you with?
True or false only animal cell has centrioles?
True. Only animal cells contain centrioles housed in centrosome.
What is responsible for forming spindle during mitosis?
The centrioles within the cell form the mitotic spindle.
What do centrioles produce?
Centrioles are involved in producing the microtubules that make up the mitotic spindle during cell division. They help organize and separate chromosomes during mitosis and are essential for cell division.
Does crossing over involve centrioles?
No, crossing over does not involve centrioles. Crossing over occurs during meiosis when homologous chromosomes exchange genetic material, while centrioles are organelles involved in organizing the spindle fibers during cell division.
What act as focal points for the growth of the mitotic spindle?
Centrosomes are the main focal points for the growth of the mitotic spindle in eukaryotic cells. They contain pairs of centrioles that organize microtubules during cell division. The microtubules extend and form the spindle apparatus, which helps separate the chromosomes during mitosis.
What is the structure located between the centrioles of a cell?
The structure located between the centrioles of a cell is the microtubule organizing center (MTOC), which helps to organize and anchor microtubules during cell division. It plays a crucial role in the formation of the mitotic spindle, which is essential for proper chromosome segregation.
True or false only animal cell has centrioles?
True. Only animal cells contain centrioles housed in centrosome.
What mitotic structures are not found in a plant cell?
Centrioles and asters .
What is responsible for forming spindle during mitosis?
The centrioles within the cell form the mitotic spindle.
During this phase of mitosis two centrioles appear to one side of the nucleus?
During this phase of mitosis, known as prophase, the centrioles move to opposite poles of the cell. As the centrioles migrate, they begin to form the mitotic spindle, the structure that will help separate the chromosomes during cell division.
During mitosis the centrioles form or organize the mitotic apparatus which is known as what?
spindle
Most neurons lack centrioles This observation explains?
the inability of most neurons to undergo cell division. Centrioles are required for the organization of the mitotic spindle during cell division. Since neurons lack centrioles, they are unable to divide and are primarily post-mitotic cells.
What organism structure that organizes motion of chromosomes?
Vesicle
Which structure organizes the mitotic spindle during cell division?
The centrosome, made up of two centrioles, plays a crucial role in organizing the mitotic spindle during cell division. The centrosomes move to opposite ends of the cell and serve as the poles for the spindle fibers to attach and pull the chromosomes apart during mitosis.
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.
What is centrioles in cell?
Centrioles are present in animal cells.Cannot be seen in plant cells.
What do the centroles do for the cell?
The centriole is the organizing center of the cytoskeleton. During the division phase of the cell-cycle, the centriole divides, the two resulting centrioles move to opposite ends of the cell. Then, the protein fibers that form between them penetrate the decomposing nuclear envelope, attach themselves to the chromosomes, and pull them into the midline between the two centrioles, aligning the chromosomes in the equatorial plane. The centrioles, the tractor (protein) fibers, and the chromosomes together form the mitotic spindle. In the next step, the spindle shortens and the chromosomes split into sister chromatids, which migrate to the two centrioles.
