Second, i decided on the Debate topic. Since we are studying on Bio this term, i think its better if the topic is on bio.
Its kinda long, got it from a Science forum, so have fun Brain Storming!
DNA, chromosomes and genes contain the information which tells a cell what type of cell to be, how long it should live for, how frequently it should reproduce and all that kind of thing.
It seems baffling that all this information on how a cell should grow, behave and reproduce could be stored in such a relatively small space. But there is a lot more going on at a microscopic (subatomic?) level than anyone can imagine.
However, when cells reproduce, the child cell doesn't always have to be an exact copy of the parent cell. For instance, skin cells presumably sometimes produce nerve cells, eye wall cells produce iris cells, etc etc. As far as our understanding goes, this is achieved by the parent cell modifying the DNA markers of the child cell. How does the parent cell know to do this?
But how does a cell know to do this? Even on a simple parent-child cell division this seems incredible. But considering the enormous amount of information that must be passed on all the way from an original embryonic cell to, say, a brain cell, how on earth is this possible?
It almost seems as if cells just know what to do. They seem to know exactly what they should do, how they should behave, what their function is, from their original instructions. But they also know exactly what their offspring should do and are able to pass this information on. And their offspring, in turn, do the same to their own offspring. All of this information must therefore be stored in the original stem cell? If so, how is it stored?
Thus,
Is the process of cell division and growth of an organism a kind of evolution in itself?
Is it possible that cells have some kind of intelligence and memory? If not, how else can this be explained?

I know its kinda long, but still, try to brainstorm on this question. Give your opinion through the Tagboard. But do NOT spam. Well, at least try not to. Here are the rules:
1) TRY not to spam. If your opinion is long, so be it, i can't stop you.
2)RESPECT other's opinions, if you want to say something to correct the person or who knows what, be polite.
3)If you feel hurt from what other's say, do not lash back. Just say so. In a nice way. Or a hurt way. But no Cursing or vulgars or anything.
Deal?
Set.
You may now start. Have funs!!!
