What are centrioles and its function?
Centrioles are cylindrical structures found in animal cells that are involved in organizing microtubules during cell division. They play a crucial role in forming the mitotic spindle, which helps to separate chromosomes during cell division.
How do asters reproduce?
Asters can be reproduced sexually by seeds and asexually by dividing the plant.
What happens during mitosis?
The chromosomes condense and turn into 2-strand chromatids; the nuclear membrane disappears; centrosomes turn to asters and a spindle fiber begins to form. Metaphase: The chromosomes align at the center of the cell (equatorial plate) and each chromosome is attached to the spindle fiber Anaphase: The chromatids (1 strand) separate and the centromere divides, where each single strand chromatid ascends to opposite poles of the cell (polar ascension) Telophase: The cellular membrane cleaves and the nuclear membrane appears again and the asters turn into centromeres once again We end up with 2 daughter cells each maintaining the same number of chromosomes that the mother cell has (2n) because mitosis is and equational division which preserves the genetic information.... Hope this helps...
Do plant cells contain aster?
No, aster is a structure found in animal cells during cell division to help organize the mitotic spindle. Plant cells do not have asters because they have a different mechanism for spindle organization during cell division.
What would happen if the cell did not contain centrioles?
mitosis & meiosis would not proceed normally. the centrioles are responsible for helping form the spindles which pull the chromatids to either side of the dividing cell. so if u didn't have the centrioles (form the asters) then the divided cells would not have an equal numbers of chromosomes at the end. http://dictionary.reference.com/browse/centrioles see second def. listed
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 does an aster do in mitosis?
Asters assist in the cell division. They help the cell divide in two.
What mitotic structures are not found in a plant cell?
Centrioles and asters .
What is the major function of asters of centrosome in a cell?
The major function of asters in the centrosome is to help organize and control the movement of microtubules during cell division. They are essential for proper spindle formation and chromosome segregation during mitosis. Asters also play a role in positioning the centrosome within the cell.
What phase is asters are formed?
Asters are formed during the prophase of mitosis in animal cells. They are structures made up of microtubules that radiate from the centrosomes, which help in the organization and separation of chromosomes during cell division. The formation of asters is crucial for the proper alignment and segregation of chromosomes to ensure accurate cell division.
After the pairs of chromosomes are lined up in the middle of the cell and the cell splits in half toward what structure do the chromosomes move?
asters♥katherinebby' novanet answer
Around what structure or structres do the asters occur?
Asters are star-shaped microtubule arrays found in animal cells. They form around the centrioles during mitosis and help ensure each daughter cell has the appropriate number of chromosomes.
What organelles form the asters and the spindle fibers?
The centrioles in animal cells form the asters and the spindle fibers.
What stage of mitosis are the centrioles and asters visible?
The centrioles and asters are visible in the mid-prophase stage of mitosis.
Which cells would need a large number of mitochondria to function and survive?
They form asters in cell division.They also organize micro tubules in division.
An aster forms during this stage of mitosis?
An aster forms during the prophase stage of mitosis. Asters are composed of microtubules radiating from the centrosomes located at opposite poles of the cell. They help to organize and separate the chromosomes during cell division.
What is the function of an aster?
Asters are microtubules(components of the cellular cytoskeleton) produced by centrioles. Their function is to hold the two centrioles in place at the two poles of the cell during cell division(mitosis). Spindle fibres produced by the centrioles are also microtubules which help in organising chromosomes at the equatorial plane of the cell during metaphase. Mitosis in which asters are formed is called astral mitosis.
