What organelle coordinates the movement of chromosomes during mitosis in animal cells?
The organelle that coordinates the movement of chromosomes during mitosis in animal cells is the centrosome. The centrosome serves as the main microtubule organizing center, producing spindle fibers that attach to chromosomes at their kinetochores. These spindle fibers help align and separate the chromosomes, ensuring their proper distribution into the daughter cells.
Which cell part structures involved in mitosis in animal cells only?
Centrioles are cell structures involved in mitosis in animal cells only. They are responsible for organizing the microtubules that form the spindle fibers necessary for separating chromosomes during cell division.
Why mitosis in animal cell is amphi astral?
Mitosis in animal cells is "amphi astral" because the spindle fibers, which help separate the chromosomes, are arranged in a star-like configuration at both poles of the cell. This configuration is essential for ensuring the accurate segregation of genetic material into two daughter cells during cell division.
Are Asters absent in plant cell mitosis or animal cell mitosis?
Asters are present in animal cell mitosis but absent in plant cell mitosis. In animal cells, asters are formed by the centrosomes during the organization of the mitotic spindle, helping to anchor the spindle fibers. In contrast, plant cells lack centrosomes and instead form a spindle apparatus without the formation of asters, relying on microtubules that emanate from the nuclear envelope and other structures.
What are the cells that can be found only on animal cells during mitosis?
During mitosis in animal cells, one key feature is the presence of centrioles, which are structures that help organize the mitotic spindle. Animal cells also form a cleavage furrow during cytokinesis, allowing for the physical separation of daughter cells. These features are distinct to animal cells, as plant cells instead form a cell plate during division.
What are the fibers that form around centrioles of an animal cells during the reproduction of the nucles?
Spindle fibers form from centrioles of animal cells during chromosomal separation in mitosis. These fibers elongate to reach the kinetochores of chromosomes, and then retract via depolymerization from each end of the dividing cell leading into cytokinesis.
During mitosis in animal cells spindle fibers extend from the centrioles which are located at opposite sides of the cells true or false?
true
What organelle structures involved in mitosis in animal cells only?
In animal cells... Centrioles, asters and the spindle fibers.
What organelle coordinates the movement of chromosomes during mitosis in animal cells?
The organelle that coordinates the movement of chromosomes during mitosis in animal cells is the centrosome. The centrosome serves as the main microtubule organizing center, producing spindle fibers that attach to chromosomes at their kinetochores.

Which cell part structures involved in mitosis in animal cells only?
Centrioles are cell structures involved in mitosis in animal cells only. They are responsible for organizing the microtubules that form the spindle fibers necessary for separating chromosomes during cell division.
What does not distinguish mitosis in plant cells from mitosis in animal cells?
A plant cell, during mitosis, has no centriole, so in the second phase [metaphase], spindle fibers do not connect to the [missing] centriole that move in opposite directions in animal cell mitosis. Also, instead of having a cleavage, like in animal cell mitosis, a cell plate forms. Animal cells do not have centrioles so the spindle fibers do not connect to centrioles and move to opposite poles, spindle fibers are instead formed by microtubules. Additionally, in the telophase in plant cells, the cytoplasm does not narrow or compress, a cell plate is instead formed in the centre of the cell and this divides it into two daughter cells.
Centrioles and a starburst cluster of spindle fibers would be found in?
Centrioles and a starburst cluster of spindle fibers would be found in animal cells during cell division (mitosis or meiosis). Centrioles play a role in organizing the microtubules that make up the spindle fibers, which help separate chromosomes during cell division.
Why mitosis in animal cell is amphi astral?
Mitosis in animal cells is "amphi astral" because the spindle fibers, which help separate the chromosomes, are arranged in a star-like configuration at both poles of the cell. This configuration is essential for ensuring the accurate segregation of genetic material into two daughter cells during cell division.
Are Asters absent in plant cell mitosis or animal cell mitosis?
Asters are present in animal cell mitosis but absent in plant cell mitosis. In animal cells, asters are formed by the centrosomes during the organization of the mitotic spindle, helping to anchor the spindle fibers. In contrast, plant cells lack centrosomes and instead form a spindle apparatus without the formation of asters, relying on microtubules that emanate from the nuclear envelope and other structures.
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.
Do spindle fibers form in plant cells undergoing mitosis?
Spindle fibers do not form in plant cells during mitosis. Plant cells undergo mitosis using a specialized structure called the phragmoplast, which helps in the formation of the cell plate during cytokinesis. The phragmoplast guides the deposition of new cell wall material between the daughter cells.
What are the cells that can be found only on animal cells during mitosis?
During mitosis in animal cells, one key feature is the presence of centrioles, which are structures that help organize the mitotic spindle. Animal cells also form a cleavage furrow during cytokinesis, allowing for the physical separation of daughter cells.
