Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Single celled eukaryotic organisms use mitosis for the following reasons:
A
growth
B
repair
C
photosynthesis
D
reproduction
E
respiration
Explanation: 

Detailed explanation-1: -Single-celled organisms and certain multicellular organisms use mitosis for asexual reproduction. This includes reproduction by fragmentation, as in the case of planaria, and reproduction by budding, as in the case of sea anemones. Many plants reproduce using mitosis.

Detailed explanation-2: -In single-celled organisms, the act of mitosis is asexual reproduction. Single-celled organisms use mitosis to reproduce and distribute their DNA. Some single-celled organisms reproduce sexually as well.

Detailed explanation-3: -Some organisms can use mitosis to reproduce asexually. The offspring of asexual reproduction are genetically identical to each other and to their parent. Most single-celled, microorganisms reproduce asexually by duplicating their genetic material and dividing in half.

Detailed explanation-4: -mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. Strictly applied, the term mitosis is used to describe the duplication and distribution of chromosomes, the structures that carry the genetic information.

Detailed explanation-5: -Unicellular asexual organisms reproduce by mitosis. Mitosis results in two identical cells. Multicellular organisms use mitosis to grow and replace dead or damaged cells. Unicellular organisms rely on mitosis to divide into two identical copies.
