Which of the following is not a function of mitosis in humans?
- a. repair of wounds
- b. growth
- c. production of gametes from diploid cells
- d. replacement of lost or damaged cells
Introduction:
Mitosis is also called as equational cell division in which chromosomes are replicated and get separated into two daughter cells. During the mitosis the chromosome number remains same (46 chromosomes). Mitosis is important for tissue repair and during cell growth.
Answer to Problem 1SQ
Correct answer:
The production of gametes from diploid cells is not a function of mitosis. Therefore, option c is correct.
Explanation of Solution
Reason for the correct statement:
The mitosis is also called as uniform division. The mitosis takes place only in somatic cells not in germ cells. The meiosis is another type of cell division which takes place in germ cells which involves in the production of gametes.
Option c. is given as “production of gametes from diploid cells”.
The gametes production from diploid germ cells is not the function of mitosis in humans.
Hence, the option c. is correct.
Reasons for the incorrect statements:
Option a. is given as “repair of wounds”.
The repair of wounds is the function of mitosis. So, it is the wrong answer.
Option b. is given as “growth”.
The mitosis helps in the growth of the cell and also helps in cell division. So, it is the wrong answer.
Option d. is given as “replacement of lost or damaged cells”.
The mitosis functions as the replacement of lost or damaged cells. So, it is the wrong answer.
Hence, options a. b. and d. are incorrect.
The mitosis did not function as the production of gametes from the germ cells in humans
