CELL DAMAGE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why is it important for cells of multicellular organisms to undergo mitosis?
A
Mitosis allows for reproduction with male and female gametes.
B
Mitosis increases variation within an organism.
C
Mitosis produces cells that are different from the original dividing cell.
D
Mitosis produces cells that are identical to the original dividing cell.
Explanation: 

Detailed explanation-1: -Answer: Significance of mitosis: It helps in maintaining the same number of chromosomes in daughter cells after division. It is responsible for growth and development of multicellular organisms. It helps in repairing of damaged tissues.

Detailed explanation-2: -When one cell divides into two, both must have a copy of the genetic information. Therefore, before cell division occurs, the genes must also make duplicates of themselves so that all of the important genetic information ends up in each of the new cells.

Detailed explanation-3: -Chromosomes in the original cell are duplicated to ensure that the two new cells have full copies of the necessary genetic information. The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.

Detailed explanation-4: -All multicellular organisms use cell division for growth and the maintenance and repair of cells and tissues. Cell division is tightly regulated because the occasional failure of regulation can have life-threatening consequences. Single-celled organisms use cell division as their method of reproduction.

Detailed explanation-5: -Mitosis is important for three main reasons: development and growth cell replacement and asexual reproduction.
