Cells don't grow forever. They divide continucsly. Explain.?

Answer 1

yes that's right

Answer 2

Well, a cell can only grow so big before it's organelles can't support it.
It's like, if you grew to 10 ft tall. You're hearts and lungs and other organs aren't designed to provide blood, oxygen, and nutrients to that large of an area. So eventually, you'll die because your body can't support you.
It's the same with cells. Cells get around this by dividing when it gets to a certain growth level. The organelles of the cell are divided and two new (smaller) cells replace that one cell. Both cells are functional and it's organelles will be working at it's best (ideally). When each cell gets too big to function right, it divides again and the whole cycle repeats itself

Aside from that, old cells constantly die, so the dividing is also a way for them to reproduce and make new cells.

Answer 3

Alright, well, most everyone is answering from a biological level but microbiologically, cells reach a level where they are covering the entire surface of their biofilm (the surface their growing on), this is called a confluence. Once they reach 100% confluency (the cells are continually dividing until this point), the cells continue to divide only as often as they die. This is a mechanism cells use to maintain homeostatsis in their community. So, as a whole, cells are dividing continuously because the community stays alive. But individually, the cells aren't necessarily dividing after they reach confluency. Some are simply dying out, while other keep dividing.

To put this in perspective, cancer is the tendency of some cells to continue dividing despite the fact there's no room or nutrients. This causes cells to build up on the biofilm, hence why you get tumors when you have cancer.

Answer 4

Cells dont grow forever. They, like humans too die out over time.
They divide continously as a form of reproducing new cells. It is their form of reproduction cycle, divide. Nature works in such wonderful ways isnt it?

Answer 5

Erm - you've pretty much answered your own question... in order for us to continue living (same with all plants and critters) cells die (varies by cell type) and new cells replace the old.

Blood cells for instance have an extremely short life span and are replaced continuously whilst nerve and brain cells live for a long time and are replaced slowly.

Answer 6

Just like you don't grow and live forever, cells divide continuously. They don't get bigger forever, they have a maxiumum limit, and once they reach that limit, they divide and grow all-over again,

Answer 7

vehicle-evolution is the place the subject is ; commencing with vehicle-genesis ; existence performing spontaneously against all odds, and beating entropy ; then people descending from animals that have not have been given a soul ; the entire concern is a fairy tale for gullible adults ; a definite type of evolution could be talked approximately in the order that God located in advent ; it is undeniable ; however the virulent unprovable theories that atheists are promoting are even much less convincing the main a ways flung account of Genesis.

Answer 8

ok the process of cell division is called mitosis and one cell divedes into two cells called daughter cells which are both identical to the mother cell

Answer 9

Depending on the cell, they go through either meiosis or mitosis. Gametes (sex cells) go through meiosis, and somatic cells such as skin cells go through mitosis.

Answer 10

They divide as long as they are in ideal conditions, but they can die especially if they organism that it is in dies
