What else can I help you with?
Produce spindle fibers?
Centrioles. They are visible during metaphase, the second stage of mitosis. Added: Centrosomes. Centrioles are present in animal cells but are, seemingly, not needed to mount a spindle apparatus. Plant cells get along very well without centrioles.
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.
What organelles are crucial to separation of chromosomes?
The spindle apparatus, made up of microtubules, and the centrosomes are crucial organelles involved in the separation of chromosomes during cell division. The spindle apparatus helps in organizing and segregating the chromosomes, while the centrosomes play a role in nucleating and anchoring the spindle fibers.
Centrioles are found at the center of the?
centrioles are found at the center of the centrosome, which is an organelle found in animal cells. Centrioles help in cell division by organizing the spindle fibers that separate the chromosomes during mitosis.
What organelles are used to move chromosomes?
Chromosomes are moved during cell division by the spindle fibers, which are made up of microtubules originating from the centrosomes. The centrosomes are organelles located near the nucleus in animal cells and help to organize the mitotic spindle during cell division.
What organelles help position the nucleus and organize spindle fibers?
The organelles that help position the nucleus and organize spindle fibers are the centrosomes. Centrosomes contain a pair of centrioles, which are cylindrical structures that play a crucial role during cell division by organizing microtubules. These microtubules form the spindle fibers that facilitate the separation of chromosomes during mitosis. Additionally, the cytoskeleton, particularly microtubules, provides structural support and aids in the positioning of the nucleus within the cell.
What paired organelle involved with cell division is found in animal but not plant cells?
The centrosomes, containing the centrioles, are the source and the organizer of the mitotic spindle in animal cells, but plant cells seem to do just fine during mitosis without such organelles.
In cytoplasmic material of animal cells contain centrioles what the regions?
Centrioles are found in the centrosome region of animal cells. The centrosome is an area near the nucleus that contains a pair of centrioles. These structures play a critical role in cell division by organizing the microtubules that form the mitotic spindle.
What are the function of centrosomes?
Centrosomes assist animal cells during cell division. The centrosomes interact with the chromosomes in order to build the mitotic spindle. Additionally, the older of the two centrioles after the nucleus splits plays an important role in making the cilia and flagella.
What structures moves apart during mitosis and create spindle?
During mitosis, the centrosomes move apart and create the spindle fibers. The centrosomes, which contain two centrioles, migrate to opposite poles of the cell. These centrosomes then form the spindle fibers, which attach to the chromosomes and aid in their separation during cell division.
What phase are the centrioles begin to organize spindle fibers?
Centrioles begin to organize spindle fibers during the prophase of mitosis. In this phase, the centrosomes, which contain the centrioles, move to opposite poles of the cell, and the spindle fibers start to form from the microtubules organized by the centrioles. This organization is crucial for ensuring proper chromosome alignment and separation during cell division.
When centriol is absent in the plant cell who forms spindle fibers?
Thespindle fibres are formed by the centrosomes not the cenrioles.The centrioles come to the MTCs ( micro tubules organising centers) which are present in the centrosomes which make up the spindle fibers on which the chromosomes are held.

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 organelles are crucial to separation of chromosomes?
The spindle apparatus, made up of microtubules, and the centrosomes are crucial organelles involved in the separation of chromosomes during cell division. The spindle apparatus helps in organizing and segregating the chromosomes, while the centrosomes play a role in nucleating and anchoring the spindle fibers.
