|What would happen if the cell cycle would not take
The cell cycle is part of life, so there would
be no life as we know it without the cell
cycle. Everything alive is made of cells, and
they all divide to make daughter cells. If cells
didn't divide, they'd just get bigger until they
got so big that they fell apart.
Before the beginning of life, scientist think
there were collections of molecules similar to
some of the ones in cells. Somehow those
molecules joined together to make bigger
molecules, with the help of some energy source
such as solar energy. The bigger molecules
arranged and rearranged and combined to form even
more complicated collections of molecules, with
the help of energy. When complicated collections
of molecules form, they often can do new things
that the separate molecules can't do. For
example, there are protein molecules that come
together and make little tubes. This kind of
thing happened over and over again in different
ways to create the life we have on earth. But
before the cell cycle, there wasn't life as we
If the cell cycle doesn't take place for a
single cell, that cell will not reproduce.
This is normal for certain types of cells,
especially neurons. But it is a problem for most
other types of cells, for example, skin cells.
These usually reproduce constantly to protect the
organism from damage, normal wear and tear, and to
ensure it is still protected as it grows.
I think the most general way to think about your
question is this: every cell that reproduces
does so for a reason, usually to help an organism
grow. If those cells cannot reproduce, it will
probably harm the organism in some way. (The
exception is cancerous cells, which reproduce
without serving a purpose to the organism.)
