What execute you think this colorful snapshot shows? If girlfriend guessed that it’s a snapshot of a cabinet undergoing cell division, you room right. But an ext specifically, the image is a lung cabinet stained v fluorescent water undergoing mitosis, throughout early anaphase.

Mitosis and also Cytokinesis

During mitosis, once the cell core divides, the 2 chromatids that make up each chromosome separate from each other and move come opposite poles that the cell. This is shown in Figure below. You can watch an animation of the procedure at the adhering to link:http://www.lifwynnfoundation.orglogy.arizona.edu/Cell_lifwynnfoundation.org/tutorials/cell_cycle/MitosisFlash.html.

Mitosis is the step of the eukaryotic cell cycle that occurs between DNA replication and the formation of two daughter cells. What happens during mitosis?

Mitosis in reality occurs in four phases. The phases are referred to as prophase, metaphase, anaphase, and telophase. Lock are presented in Figure below and also described in greater information in the complying with sections.

*

Metaphase

During metaphase, spindle fibers affix to the centromere of each pair of sister chromatids (see Figure below). The sister chromatids line up in ~ the equator, or center, of the cell. This is additionally known together the metaphase plate. The spindle fibers ensure that sister chromatids will separate and also go to various daughter cells once the cell divides.

*

Chromosomes, consists of sister chromatids, line up at the equator or middle of the cell during metaphase.


Anaphase

During anaphase, sister chromatids separate and the centromeres divide. The sister chromatids are pulled apart by the shortening of the spindle fibers. This is like reeling in a fish by shortening the fishing line. One sisters chromatid move to one pole that the cell, and the other sister chromatid moves to the contrary pole. In ~ the finish of anaphase, every pole that the cell has a complete collection of chromosomes.



Cytokinesis

Cytokinesis is the last stage that cell division in eukaryotes and also prokaryotes. During cytokinesis, the cytoplasm splits in two and the cabinet divides. Cytokinesis wake up somewhat in different way in plant and animal cells, as displayed in Figure below. In animal cells, the plasma membrane the the parental cell pinches inward along the cell’s equator until two daughter cells form. In tree cells, a cell plate forms along the equator of the parental cell. Then, a brand-new plasma membrane and also cell wall form along every side of the cabinet plate.

Cytokinesis is the final stage of eukaryotic cell division. It occurs differently in animal (left) and also plant (right) cells.

The four phases that mitosis. Deserve to you describe what happens in each phase?


Summary

Cell division in eukaryotic lifwynnfoundation.org cells includes mitosis, in which the nucleus divides, and also cytokinesis, in which the cytoplasm divides and daughter cells form. Mitosis occurs in 4 phases, dubbed prophase, metaphase, anaphase, and telophase.
