What else can I help you with?
What is the name of the organelles from the asters and the spindle fibers?
The spindle fibres are in the nucleus and they are envolved in mitosis.
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 organelles produce spindle fibers?
Centrioles. They are only found in animal cells and produce the spindle fibers during cell division (namely, Metaphase). One set is located at each pole of the cell.
At which phase of meiosis 1 do spindle fibers form?
Spindle fibers form during the prophase stage of meiosis 1.
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.
Do the centrosomes form spindle fibers?
yes
Cell structures made of individual microtube fibers that are involved in moving chromosomes during cell division are called?
Spindle fibers. These structures form the mitotic spindle and play a crucial role in separating chromosomes during cell division.
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 stage to spindle fibers begin to form?
Prophase.
In what phase do spindle fibers form from the centrioles?
Spindle fibers are thin tubes that form between the centrioles during mitosis. True..
Why is the structure responsible for the movement of chromosome during anophase?
The Centrosome. It forms Centrioles which form spindle fibers. Some of the spindle fibers attach to the Kinetochore located on the Centromere of chromosomes. The spindle fibers work in conjunction with motor proteins to facilitate disjunction.
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.
