Are centrosomes found in animal or plant cells?
Centrosomes are found in animal cells. They play a crucial role in cell division by organizing the microtubules that form the mitotic spindle. Plant cells do not have centrosomes but use other mechanisms to organize their microtubules during cell division.
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 structure does spindle fibers radiate from?
The centrosomes.
Where are originate the microtubules that form the mitotic spindle?
Microtubules that form the mitotic spindle originate from the centrosomes, which are found near the nucleus in animal cells. The centrosomes serve as the main organizing centers for microtubule assembly during cell division. Additionally, some microtubules can also originate from non-centrosomal sites in the cell.
What do Centrosomes look like?
Centrosomes are typically spherical or oval-shaped organelles found near the nucleus of animal cells. They consist of two centrioles that are perpendicular to each other and surrounded by pericentriolar material. Centrosomes play a crucial role in organizing microtubules during cell division.
Do the centrosomes form spindle fibers?
yes
Cells would be unable to form cillia or flagella if they did not have what?
Cells would be unable to form cilia or flagella if they did not have microtubules. Microtubules are a component of the cytoskeleton that provide structural support and facilitate the movement of cilia and flagella.
What type of cell has centrosomes?
Animal cells have centrosomes.
Fill in the blank form and attach to centrosomes which are found at opposite poles of the cell?
spindle fibers.

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 structures do spindles originate?
Spindles originate from the centrosomes, which are small organelles found near the cell nucleus. The centrosomes organize microtubules to form the spindle apparatus during cell division, ensuring proper chromosome segregation.
Are centrosomes necessary for mitosis?
Actually, while centrosomes play a big part in interphase of mitosis, they are not needed for cell reproduction. Studies have shown that the spindle-fibers still form via motors at the poles of the cell.
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.
Is the role of centrosomes necessary for mitosis?
Yes, centrosomes play a crucial role in organizing the microtubules that form the mitotic spindle, which helps separate chromosomes during mitosis. However, some cells can undergo mitosis without fully functional centrosomes, using alternative mechanisms for spindle formation.
Microtubules begin to assemble at the?
centrosomes
Where do centrosomes migrate to?
