Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Growth and replacement of cells (repair)-asexual reproduction
A
MITOSIS
B
MEIOSIS
Explanation: 

Detailed explanation-1: -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-2: -Both sexual and asexual organisms go through the process of mitosis. It happens in the cells of the body known as the somatic cells and produces cells related to growth and repair. Mitosis is essential for asexual reproduction, regeneration, and growth. It does not make sex cells or gametes.

Detailed explanation-3: -One of the key differences in mitosis is a single cell divides into two cells that are replicas of each other and have the same number of chromosomes. This type of cell division is good for basic growth, repair, and maintenance. In meiosis a cell divides into four cells that have half the number of chromosomes.

Detailed explanation-4: -To grow and repair themselves, cells combine amino acid molecules to form larger protein molecules. Those new proteins build new cells and cell parts. Growth and repair also require energy, so cells also need glucose and oxygen to release energy for these important functions.

Detailed explanation-5: -Mitosis is a form of asexual reproduction in simple living organisms. The outcome of each cell cycle is two identical cells. Mitotic checkpoints happen at certain stages of mitosis to ensure that each cell receives the same amount of DNA.
