Byanon137302— On Dec 27, 2010 i am a student studying in grade 8 and i am having difficulty in answering the following question: why do cells have to divide after they reach a certain size? please answer this question for me.
the DNA material in each chromosome copies itself so that exactly the same DNA is passed to the two new daughter cells that are formed. This process of cell division is calledmitosis.
Answering the question, “Why do cells divide?” pretty much also answers the question, “Why is mitosis important?” The process of mitotic cell division in eukaryotic cells is important for two main reasons: because cell division creates new cells that keep eukaryotic organisms thriving, and be...

What hormone is secreted by Sustentacular cells when sperm count is high? The Sertoli cells produce thehormone inhibin, which is released into the blood when the sperm count is too high. What is the function of spermatogenic cells? The spermatogenic cellsdivide by mitosis, then meiosis to form...
Why is it that when the cell divides in mitosis, it does not form 4 cells, but in meiosis it does? What are some other reasons cells undergo mitosis? What role is played by mitosis in human reproduction? What kind of cell division takes place in mitosis?
Define mitosis. Where does this process normally take place? What are the phases in the cell cycle and how do they relate to mitosis? What is unique to Meiosis that does not take place in Mitosis? Which cells do not divide by mitosis?
duplicate itsDNAand divide. Cell division happens through another process calledmitosis. There are several phases of both the cell cycle and mitosis. All of these phases must be completed without errors in order to ensure the health of the cells. Sometimes, however, mitosis goes wrong, and can...
Cells can grow, ormultiply, by dividing! First there was only one cell,and then it divided by a process called cell division ormitosis(有丝分裂).So then there were two cells.Then each of those cells divided, and then there werefour cells. . Well, you get the picture. Think about...
As all school-children learn, cells divide using a process called mitosis, which consists of a number of phases during which duplicate copies of the cell's DNA-containing chromosomes are pulled apart and separated into two distinct cells. Losing or gaining chromosomes during this process can lead...
