Answer:
C. Grow larger.
Explanation:
Background:
There are mainly 2 types of cell divisions that actually exist-meiosis and mitosis. Meiosis is a type of cell division in which reduces the number of chromosomes by half. Meiosis (not to be confused with mitosis) occurs in every se=3xually reproducing eukaryote and is required to produce egg and sperm cells. The result of meiosis is four daughter cells. During the S-phase of interphase, the DNA is replicated, forming two identical sets of DNA. At the beginning of mitosis, the DNA condenses and coils into structures called chromosomes. Each chromosome exists as a pair of identical sister chromatids connected by a centromere. During metaphase of mitosis, spindle fibers direct the movement of the pairs of sister chromatids to the cell's equatorial plane. The next phase is anaphase, during which one chromatid from each pair moves to opposite poles of the cell. At this point the chromatids are now individual chromosomes, and there are now two identical sets of chromosomes. Mitosis cell division occurs to mend the cells which wear off naturally and it it's also essential for the replacement of the cells which die due to injuries. This type of cell division is the key reason for growth. During telophase and cytokinesis, the cell divides into two cells, each with identical sets of chromosomes.
----------------------------------------------------------
The reasons why cells divide can be for numerous purposes-
- As seen from the perspective of mitotic division, in which the no of chromosomes is conserved,i.e.,46 chromosomes in human somatic cells. Cells can divide through mitosis to replace the worn out or dead cells in the body of living organism.
- Another reason why cell division is required and takes place can be to form the germ cells/gametes/s3x cells(sperm and ovum). In this case the no of chromosomes is halved (23 chromosomes present in sperm and egg cells each).
Both of these types are required for a particular living organism and needs specific ways that they could be divided. These are probably the two most important reasons why cell division occurs.
----------------------------------------------------------
Why Cells Divide:
- As a result, if a cell grows rather than divides, diffusion will be too sluggish, and the cell will be unable to absorb nutrients and dispose of wastes adequately, eventually killing the cell. Despite the fact that cell size is restricted, cells divide to allow an organism to grow.
