Your question: What is mitotic apparatus give its function?

a temporary structure in a dividing cell that enables the chromosomes to move to the poles of the cell, thus ensuring their even distribution between the daughter cells. The mitotic apparatus is formed from macromolecules present in the interphase cell and from material synthesized before division. …

What is mitotic apparatus Class 11?

Mitotic apparatus is the structure formed during mitotic cell division in order to split or separate the sister chromatids in between the daughter cells. … Green algae undergo mitotic division as seen through the microscopes therefore mitotic apparatus is present in the green algae.

What are the 3 components of the mitotic apparatus?

The mitotic spindle is a special device essential for chromosome segregation ( mitosis) during cell division. It consists of three parts, chromosomes, two asters and a spindle region (Fig. 1).

What are the two parts of the mitotic phase?

Mitosis Is Divided into Well-Defined Phases. … Flemming divided mitosis into two broad parts: a progressive phase, during which the chromosomes condensed and aligned at the center of the spindle, and a regressive phase, during which the sister chromatids separated.

What is difference between mitotic and mitosis?

Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.

What do you mean by mitotic?

Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

What is the mitotic apparatus made of?

In eukaryotic cells, the mitotic apparatus is composed of two centrosomes and spindle microtubules (Figure 43.9). The centrosome is 1–2 μm in diameter. Each centrosome is composed of two centrioles of approximately 20 nm in diameter surrounded by a pericentriolar matrix.

What is the function of a cell plate?

A disc like structure in the plane of the equator of the spindle that separates the two sets of chromosomes during cytokinesis; also involved in the formation of cell wall between the two daughter cells following cell division.

What do you mean by spindle apparatus?

Definition. Any of a network of filaments that collectively form a mitotic spindle (in mitosis) and meiotic spindle (in meiosis). It is chiefly involved in moving and segregating the chromosomes during nuclear division.
