Where do the microtubules of the spindle originate during mitosis in both plant and animal cells?
In plant cells, the microtubules of the spindle originate from the microtubule-organizing centers (MTOCs) located at opposite poles of the cell. In animal cells, the microtubules of the spindle originate from the centrosomes, which are also located at opposite poles of the cell.
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.
Do plant's cells have centrioles?
No, plant cells do not have centrioles. Centrioles are only found in animal cells and are involved in organizing the microtubules during cell division. Plant cells use a different mechanism to organize their cytoskeleton during cell division.
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.
A fanlike microtubule structure that helps separate the chromosomes is a?
mitotic spindle. It is composed of microtubules and plays a crucial role in ensuring the accurate distribution of chromosomes during cell division.
What type of cell is spindle fibers?
Spindle fibers are not cells but components of cells which are essential in the process of cell division. In animal cells, the spindle fibers are formed by centrioles; however, in plant cells, there is no apparent organizer of the spindle fibers.
What is the general shape of smooth muscle cells and plant fibers?
Smooth muscle cells are long, spindle-shaped cells with a central nucleus. Plant fibers are elongated cells with thick cell walls that can be either round or polygonal in shape, depending on the plant species.
Are Centrioles necessary for spindle formation?
Centrioles are important for spindle formation in animal cells, as they help to organize the microtubules that make up the spindle apparatus. However, some cells, such as plant cells, can form functional spindles without centrioles.
Where do the microtubules of the spindle originate during mitosis in both plant and animal cells?
In plant cells, the microtubules of the spindle originate from the microtubule-organizing centers (MTOCs) located at opposite poles of the cell. In animal cells, the microtubules of the spindle originate from the centrosomes, which are also located at opposite poles of the cell.
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.
Are centerioles found in plant cells?
no as plants lack spindle at the time of cell division.
What does not belong cleavage furrow cytokinesis spindle fiber cell plate?
Cleavage furrow.Cell plate formation only occurs in plant cells. Spindle fiber is found in plant cells and cytokinesis occurs in plant cells.Cleavage furrow doesn't occur in plant cells and is the only one not to.

mitotic spindle. It is composed of microtubules and plays a crucial role in ensuring the accurate distribution of chromosomes during cell division.
Are centrioles and starburst clusters of spindle fibers found in plants?
Centrioles are not found in plant cells, but they have structures called basal bodies that function similarly. Starburst clusters of spindle fibers are not found in plant cells either; plant cells have a diffuse network of microtubules called the preprophase band that helps orient the division plane during cell division.
Do plant cells lack centrioles while animal cells do not?
Yes, plant cells lack centrioles, which are organelles that help organize microtubules during cell division in animal cells. Instead, plant cells rely on other structures like the spindle poles to assist in this process.
