Differences In The Cell Cycle Events Between Animal, Plant, And Bacterial Cells

941 words - 4 pages

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 ...view middle of the document...

At this particular time, the chromosomes cannot be seen and they go back to their uncondensed state. Unlike in plants, a group of cytoskeletal proteins are created between the nuclei at the future of another cell wall formation. One more difference is observed in animal cell where a contractile ring is created around the center of the cell (Eckardt, 2012).
The Cytokinessis reveals the most distinctive features that exist in cytokinesis of bacteria, animals, and plants. This involves the division of cytoplasm prior to the equal bisection of hereditary material into two cells. Even though both plants and animal cells share similar features in the DNA replication, there are some clear differences observed during this stage. In bacteria cell, the round chromosome attaches itself to the plasma membrane at one end, which is then replicated. As the cell gets longer, a membrane is added separating the attachments ends pushing them separately. As both chromosomes move apart, the membrane grows towards the inner side at the center of the cell. Then, the mother cell bisect into two parts to complete binary fission. Every daughter cell obtains exactly single DNA duplicate and at least half of the cytoplasm (Starr et al, 2012).
In animals, cytokinesis usually starts during telophase stage following chromosome segregation competition. Initially, microfilaments attaching on the membrane create a ring surrounding the cell’s center. The ring later contracts to constrict the center of the cell. Consequently, the equator is pinched through contracting down to nothing and partitions the cytoplasm into two equal daughter cells.
In cytokinesis in plants, there are two distinctive events that happen during the cell division. Originally, the nucleus should move towards the core of the cell prior to the beginning of mitosis. The nucleus is anchored at first by cytoplasmic strands that gradually unite forming a transverse cytoplasm...

As soon as enough growth had occurred, the cell would begin the "S" phase, eventually leading to mitosis and cell division.Between 600 and 400 million years ago, some eukaryotes became multicellular (animals, plants, fungi). Most of their cells now divide only a limited number of times before pausing in "G1" and specializing. These cells

Mitosis In Animal And Plant Cells

This is a process in which animal and plant cells differ. In animal cells, the cytoplasm and all of its contents divide between the two halves of the cell, then the cell membrane pinches inward in both sides between the two poles until two daughter cells are formed. In plant cells, a number of small vesicles combine at the metaphase plate to form the cell plate. Over time, the cell plate reaches across the cell and joins with the plasma membrane.
