How cytokinesis occurs in plant cells?

Question

Answer

By cell plate formation...fragmoplast...

Answer

Cytokinesis in plant cell occurs by cell plate formation by Golgi bodies which stars from centre and moves centrifugally outwards to join outer wall as a result cell divides into two

Answer

Cytokinesis in Plant Cells. Plant cells have walls, so cytokinesis cannot proceed with a cleavage furrow. Instead, during telophase a cell plate forms across the cell in the location of the old metaphase plate. A new cell wall forms between the two membranes of the cell plate.

Answer

Cytokinesis is the final stage of cell division, during which the cytoplasm of a cell is divided into two daughter cells. In plant cells, cytokinesis differs from animal cells due to the presence of a rigid cell wall. The process of cytokinesis in plant cells can be divided into several key steps.

**Formation of the Cell Plate:**
During late telophase, microtubules and vesicles derived from the Golgi apparatus assemble at the equator of the dividing cell. These vesicles fuse together to form a flattened, disk-like structure called the cell plate. The cell plate gradually expands outward towards the cell walls.

**Growth and Maturation of the Cell Plate:**
As the cell plate grows, it accumulates additional vesicles and materials from the Golgi apparatus. These materials include cell wall components such as cellulose, pectin, and other polysaccharides. The cell plate continues to expand until it reaches the edges of the cell, dividing it into two compartments.

**Formation of the Midline:**
The cell plate enlarges and fuses with the existing cell wall, forming a new cell membrane that separates the two daughter cells. At the center of the cell plate, a thin line called the midline develops. The midline is composed of microtubules and actin filaments that help guide the formation of the new cell wall.

**Deposition of Cell Wall Material:**
Vesicles derived from the Golgi apparatus fuse with the midline, depositing cell wall materials such as cellulose and other polysaccharides. The deposition of these materials strengthens the cell plate and facilitates the formation of a new cell wall between the daughter cells.

**Completion of Cell Separation:**
As the cell wall material continues to be deposited, the cell plate expands further and the daughter cells become more distinct. Eventually, the cell plate matures into a fully formed cell wall, completely separating the daughter cells.

By the end of cytokinesis, the plant cell has successfully divided into two separate daughter cells, each containing their own nucleus and organelles. The new cell wall formed during cytokinesis provides structural support and maintains the integrity of the daughter cells.

Assertion : In animal cells, the cytokinesis is marked by the appearance of a furrow in plasma membrane.Reason : In plant cells, the formation of the new cell wall starts with the formation of simple precursor called cell plate.

Cell wall is presant in plant cells or animal cells?

which type of cell division occurs im haploid cells?

name two plant cells in which cell wall is absent...???

As we know that centrioles are present in animal cells only . Centrioles help in chromosome segregation during cell division. . But in case of plant cell centrioles are absent .what is the mechanism in case of plant cell for chromosome segregation. .???? Can anybody explain its mechanism?
