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.

What two ways that cell division is regulated in healthy cells?
internal and external factors regulate the cell cycle
Why is it important that cell growth in a multi- cellular organism be regulated so carefully?
In multicellular organisms, cell division must be carefully regulated to ensure that growth of the organism is coordinated, replacement of dead cells takes place in an orderly fashion, and repair of injured cells is initiated when needed. Cell division must also be halted when growth and repair are completed. Cell division is controlled by a variety of factors. One of the most important controls is carried out by molecules called growth factors.
Is it true that the cell cycle is regulated very tightly?
The cell cycle is regulated by three checkpoints viz G1, G2 and Meta phase checkpoints. Check points help to detect DNA damage and repair it. If repair is not possible then it generate signals to destruct the cell via apoptosis. Hence the statement is true. true
How is cell division related to the cell cycle?
If there would not have been any cell division, no life would have exists as there would not have been any reproduction of cells and the first cell ever would have died leaving no trace at all. Each cell prior to its division has to pass through S, G1 & G2 phases to prepare for its division. The actual message for cell division by mitosis or meiosis is received during its entry to cell cycle.
Do lysosomes initiate cell division in animal cell?
No, centrosomes initiate and regulate cell division in plants.In cell biology, the centrosomeis an organelle that serves as the main microtubule organizing center (MTOC) of the animal cell as well as a regulator of cell-cycleprogression.Lysosomes ,better known as Suicide bags,use enzymes to destroy the other damaged cell organelles.

What role does p53 have in controlling cell division?
Cell division is regulated by the p53 gene and relates to cancer because Cancer is caused by uncontrolled cell divison
What is it call when Leaf blades grow larger as a result of cell division?
This process is called leaf expansion, where the leaf blades increase in size due to cell division and cell enlargement. This growth is often regulated by hormones such as auxins and gibberellins.

What type of disease may result if the cell division is not properly regulated?
Cancer. A cancerous tumor is a group of cells that divide uncontrollably, without stopping.
What are the key differences between normal cell division and cancer cell division?
Normal cell division is tightly regulated and controlled by the body to ensure that cells divide at the right time and in the right amount. In contrast, cancer cell division is uncontrolled and can happen rapidly and uncontrollably, leading to the formation of tumors. Additionally, cancer cells can invade nearby tissues and spread to other parts of the body, a process known as metastasis, which normal cells do not do.
