Question

Significance of mitosis is in
A)Occurrence in every tissue of body
B)Increasing cellular mass
C)Swift division
D)Producing cells genetically similar to parent cell

Answer 1

Cell division is the process by which the cells divide into two or more daughter cells. The mitosis takes place in the somatic cells which are not involved in producing gametes. whereas meiosis takes place in the sex cells.

Complete answer:
Mitosis is the process of cell division which takes place in the somatic cells. The process of mitosis takes place in all the tissues except germ cells. The mitosis occurs in four phases prophase, metaphase, anaphase and telophase. The mother cell splits into two identical cells which are genetically similar.
The characteristics of cell division:
1)The mitosis takes place for growth and replacement of worn-out cells.
2)It only occurs in somatic cells.
3)The chromosome number is not reduced in mitosis.
4)The genetic recombination does not take place in mitosis so the daughter cells produced are genetically identical.
5)The aberrations that take place in mitosis can lead to genetic disorders.

Hence, the correct answer is option (D)

Note: Mitosis is the fundamental process for life. It is a single division process which is called an equational division. The meiosis takes place in the germ cells and is a reductional division. The meiosis involves intermixing of genetic material by the process of crossing over. Mitosis involves division of the nucleus. As the prokaryotes do not have a definite nucleus, they do not undergo proper mitosis.
