Compare and contrast cytokinesis in animal and plant cells.

Cytokinesis occurs in both animal and plant cells. It is the division of the cytoplasm, which is the final stage of the cell cycle. In animal cells, the cell membrane pinches together around the middle of the cell to divide the cytoplasm. In plant cells, the process is a little different. Because the cell wall of a plant cell is rigid, it does not pinch in like the more flexible cell membrane in animal cells. Instead, a structure called a cell plate forms across the middle of the cell. The cell plate moves outward and eventually fuses with the cell membrane to divide the cell into two cells. Then, new cell walls form around the cell membranes.

Cytokinesis in animal and plant cells contrasts as follows:

In animal cells, the cytokinesis process involves the formation of a division groove on the cell surface that extends and deepens until the cell divides in two.

This is due to the contraction generated by the contractile ring, composed of filaments of actin, myosin, and other structural and regulatory proteins.

As the ring narrows, the groove will be larger and the cytoplasm will be strangled until it reaches the point of cell separation. Eventually, the two daughter cells are formed.

On the other hand , cytokinesis in plant cells takes place after the formation of a separating septum known as a phragmoplast, which arises from the accumulation of vesicles that come from the Golgi apparatus and that contain material from the cell wall.

Once the phragmoplast comes into contact with the cell walls, the septum will form in the middle of the cell, making cell division possible.

Comparisons between both cytokinesis:

In animal cells, cytokinesis occurs by strangulation, while in plant cells it occurs by septation.

The plant cell uses its vacuoles to increase its volume against cytokinesis while the animals do it through synthesis, which causes a greater energy expenditure.

During cytokinesis the plant cells do not lose width in the center while with the animal cells due to strangulation they narrow.

Therefore, we can conclude that cytokinesis is a cellular process whose purpose is the division of the stem cell's cytoplasm between daughter cells, it is not the same in animal and plant cells due to the physiological characteristics of each one.
