Answer in detail:
With the help of suitable diagrams explain the mitosis in detail.

Explanation

i. Mitosis is the process of cell division occurring in somatic cells and stem cells. It is essential for the growth of the body, restoration of emaciated ( weak and itll ) body, wound healing, formation of blood cells, etc.
ii. It is completed through two main steps namely, karyokinesis ( nuclear division) and cytokinesis ( cytoplasmic division ) .
iii. Karyokinesis occurs via. four steps, i.e., prophase, metaphase, anaphase and telophase.
a. Prophase `:` During this phase thread like chromosomes condense. The centrioles duplicate and move to the opposite poles of the cells. The nuclear membrane and nucleolus starrt disappearing.
b. Metaphase `:` During metaphase, the nuclear membrane completely disappears . Chromosomers complete condensation and become clearly visible along with sister chromatids. The chromosomes arrange parallel tothe equatorial plane of the cell. Spindle fibers are formed between the centromers of each chromosome and both the centrioles respectively.
c. Anaphase `:` The centromeres split and the sister chromatids are pulled apart in opposite directions with the help of spindle fibers. The separated sister chromatids ( daughter chromosomes ) reach two opposite poles of the cells.
d. Telophase `:` Daughter chromosomes begin to decondense and the nuclear membrane is reformed around each set of chromosomes present at the poles . This results in the formation of two daughter nuclei. The nucleolus reappears in each daughter nucleus and the spindle fibers disappear completely.
iv. With the end of karyokinesis, cytokinesis begins and as a result two new daughter cells are formed.
v. During cytokinesis, a notch ( cleavage furrow ) forms at the equatorial plane that gradually deepens to form two separate cells. A cell plate is formed in the center of the cell instead of notch in case of plant cells.
