Why is cell division necessary in the body?

Answer 1

In body cells, cell division is regulated by a process

of mitosis which have five stages called Interphase, Prophase, Metaphase, Anaphase, and Telophase. In mitosis, one cell becomes into two identical cells. Also in mitosis, the cells contain the same amount of genetic information (chromosomes) that its parent cell had (diploid). In order for this to happen the DNA must be replicated like in Interphase to form pairs so the can become into two identical cells.

In reproductive cells, cell division is regulated by a process called meiosis which have four stages (Prophase, Metaphase, Anaphase, and Telophase) that only does two nuclear divisions. Unlike mitosis, one cell becomes four nonidentical cells. One cell has half the amount of chromosomes that the parent cell had (haploid). The reason why it has half is because humans need a maximum of 46 chromosomes. A reproductive cell must have 23 chromosomes in order to join with another reproductive cell or else the process won't work.

Answer 2

Cell division is necessary in the body for growth, repair, and maintenance of tissues. It allows for the development of new cells to replace damaged or old ones, and is essential for normal functioning of the body. Without cell division, organisms would not be able to grow, heal from injuries, or maintain their overall health.

Answer 3

If cells do not divide properly, then many problems can occur, cancer cells for example.

Answer 4

Cell division has to occur in order to replace dead cells and keep the body functioning. This must be controlled because unmitigated cell growth is called cancer.

Answer 5

• growth
• wound healing
• reproduction
• etc.
