Recommended: The differences between animal and plant cell
Cell cycle events portray some differences between different living things. In all the three living things, their cells divide, a process referred to as mitosis. The mitosis stage differs and it encompasses four phases. During development, the cell cycle functions endlessly with newly created daughter cells directly embarking on their path to mitosis. Bacteria cells separate forming two cells after every thirty minutes under favorable conditions. However, the eukaryotic cells take quite longer compared to bacteria cells to develop and divide. Nevertheless, in both animals and plants, cell cycle is usually highly regulated to prevent imbalanced and excessive growth. Both animals and plants are known as eukaryotes meaning that their DNA exists inside their cells’ nuclei. Therefore, their cells as well as mitotic processes are similar in various ways (Eckardt, 2012).
During interphase, the cells in both animals and bacteria carry out their division general functions according to the type of their cells. Unlike in plants, a preprophase group of cytoskeletal proteins emerge at a future location of the cell plate. At prophase stage, duplicated chromosomes compress in a way that can be seen with the help of a microscope. On the other hand, the mitotic spindle is formed at one side of nucleus, whereas in plants, spindle is formed around the nucleus. During prometaphase in animals and bacteria, the nuclear membrane disappears, the chromosomes attach themselves to mictotubules and start to move. In plants, however, the preprophase group dissolves while at metaphase stage, the chromosomes get aligned at the core of the cell. At anaphase, there are fewer differences between animals and plants. The chromosomes shift apart towards the both par...

...er with the plasma membrane all over the edges of the cell, thereby completing the division of both daughter cells. In the middle of both plasma membranes stretch out on the central lamella that bisects the daughter cells. Every daughter cell then leaves a primary wall just next to the central lamella. Additionally, each of the two daughter cells deposits another primary wall layer all over the whole protoplast. The new wall formed combines with the cell plate’s wall to form one complete wall. The original cell wall enlarges until it ruptures because of the growth and expansion of the two daughter cells (Starr et al, 2012).

There are many different cells that do many different things. But all of these cells fall into two categories: prokaryotic and eukaryotic cells. Eukaryotic cells contain a nucleus and are larger in size than prokaryotic cells. Prokaryotic cells do not contain a nucleus, are smaller and simpler than eukaryotic cells. Two of their similarities are they both have DNA as their genetic material and are covered by a cell membrane. Two main differences between these two cells are age and structure. It is believed that prokaryotic cells were the first forms on earth. They are considered primitive and originated approximately 3.5 billion years ago. Eukaryotic cells have only been around for about a billion years. There is strong evidence that suggests eukaryotic cells may be evolved from groups of prokaryotic cells that became interdependent on each other (Phenotypic analysis. (n.d.).

10.4) In animal cells cytokinesis involves the formation of a cleavage furrow which pinches the cell in two. While in plants cells cytokinesis involves the division of cytoplasm by late telophase, so the daughter cells appear shortly after the end of mitosis.

In telophase, these separate chromatids uncoil to become chromosomes. This division produces two identical cells.

The process of mitosis can take place in either a haploid (23 chromosomes) or a diploid (46 chromosomes) cell. Before a cell can be ready for a mitotic division it must primarily undergo its interphase stage. Following the interphase stage several other stages come into play. These stages are prophase, prometaphase, metaphase, anaphase, and telophase. During each specific stage certain sequences of events take place that assist to the completion of the division.
Prokaryotic cell: have no membrane covered organelles, they also have circular DNA and bacteria, Eukaryotic cell: have membrane covered organelles, they also have linear DNA and all other cells. Also the cell cycle is short in prokaryotic cells, roughly taking about 20-26 minutes to complete. And in eukaryotic cells, the cell cycle is long, it usually takes about 12-24 hours to complete. Below is a table of some of the differences between the cells:

The process of cell division plays a very important role in the everyday life of human beings as well as all living organisms. If we did not have cell division, all living organisms would cease to reproduce and eventually perish because of it. Within cell division, there are some key roles that are known as nuclear division and cytokinesis. There are two types within nuclear division. Those two types being mitosis and meiosis. Mitosis and meiosis play a very important role in the everyday life as well. Mitosis is the asexual reproduction in which two cells divide in two in order to make duplicate cells. The cells have an equal number of chromosomes which will result in diploid cells. Mitosis is genetically identical and occurs in all living
Mitosis is a part of the cell cycle process because chromosomes in a cell nucleus are separated into
The microtubule spindles attach to the kinetochores in metaphase II, causing the chromosomes to line up, and at the start of anaphase II, the remaining cohesins at the centromere break down, so that the sister chromatids are able to separate and move to opposite ends of the cell. (Alberts et al., 2008.) They then undergo telophase and cytokinesis to produce four haploid cells. (Lodish et al., 2008.)
A second key part of a cell is called the cell nucleus. It’s known as the commanding cell. It is the brain of the cell. It controls the eating, movement and reproduction throughout the cell. Not all cells have a nucleus. There’s the eukaryotic that does have a nucleus and the prokaryotic that doesn’t have a nucleus. Its dark spot in the middle of the cell, it doesn’t get placed on the sides of the cell because it can harm the nucleus.
