As we know that there are mainly two cell division and reproduction process; mitosis and meiosis. The process of meiosis is just limited to the sexually reproductive organisms, whereas the process of mitosis occurs in both the sexually and asexually reproductive organisms. In other words, we can say that the process of mitosis happens in all the organisms. Due to the difference of cell structure of organisms, the process of mitosis may differ from each other. Following the statement above, we came to know that the mitosis in an animal is different from mitosis in plants because of their cell structure. In an animal cell, the cell gets in round shape before the division process (mitosis) commences, whereas the plant cells don’t change the shape before the process of division. The centrosomes are the crucial part of the animal cell mitosis, on the other hand, plant cell mitosis lacks centrosomes. It should be kept noted that centrosome is the organelle near the cell nucleus, which contains the centrioles in the animal cell.
What is Animal Cell Mitosis?
The animal cell mitosis comprises of four main phases; prophase, metaphase, and anaphase like the ordinary metaphase. The major difference in this type of mitosis is due to the cell structure and functionality. As the process of Mitosis is useful for the process of growth of the fibers, tissues, and organic growth of the tissues in the organism’s body, it is not limited to any of the certain parts of the body. In other words we can say that, the mitosis can take place throughout the body in an animal cell. Before the process of division (mitosis), the cell gets itself molded in the round shape. In the animal cell mitosis, when the parent cell is further divided into two daughter cells, a furrow is formed between them. There are dozens of hormones induced to the animal’s body as it is more complex than the plant body, a specific hormone is not induced by the process of mitosis in the animal cells. The centrosome, which is the organelle present outside the cell nucleus and contains the centrioles is essential for the process of animal cell mitosis, although plant cell lacks centrosome. The other distinctive features in the animal cell mitosis are that aster formation takes place in it, and the cell plate formation, which happens in the plant cell doesn’t take place in the animal cell mitosis.
What is Plant Cell Mitosis?
The plant cell mitosis has an additional phase called preprophase that comes before one of the main functions of mitosis both in animal and plant cells. Unlike animal cell mitosis, no aster formation or no furrowing of cytoplasm at the cytokinesis takes place. The centrioles aren’t formed in the plant cell as they lack centrosomes. The process of mitosis in plants mainly occurs in the meristems of the plant. For the process of mitosis, a specific plant hormone known as cytokinin is induced in the plants. A solid lamella develops in between the two daughter cells for the process of adhesion.
Animal Cell Mitosis vs. Plant Cell Mitosis
- The animal cell changes its shape before the division, whereas the plant cell doesn’t change the shape before the division.
- The centrosome, which is the organelle present outside the cell nucleus and contains the centrioles is essential for the process of animal cell mitosis, although plant cell lacks centrosome.
- In animal cell mitosis, the aster formation takes place, while no aster formation takes place in plant cell mitosis.
- The furrowing of cytoplasm at the cytokinesis takes place in the animal cell mitosis, whereas no furrowing of cytoplasm occurs in the plant cell mitosis.
- The process of mitosis can take place throughout the body in an animal cell. Contrary to this, the process of mitosis in plants mainly occurs in the meristems of the plant.
- A specific hormone is not induced by the process of mitosis in the animal cells. On the other hand, a specific plant hormone known as cytokinin is induced in the plants for mitosis.
