Why is cell differentiation important?
lol im guess that your doing unit 1: fundimentals of science ! same as me, well if im right, the question you have been given is not very clear in what it is asking you to define. my take on the question is not that you have to go through every system in the body (brain, endocrine ect) which is what some people define as tissues BUT to explain the 4 main types of tissue in the body being; nervous, muscle, epithelial and connective tissue. so in each of those main tissues types you will find there to be different types of cells doing different functions in the tissue. Take connective tissue for example, you have loose connective tissue and dense connective tissue. you have to state that they have different proerties (loose having capibillity of holding water and dense not ect) and say why that's important to the functions and building of the body. don't be confused by the eukaryotes part that's just an other way of saying animal body. So if you go to the edexcel website and look at the speification you can see that this is onyl for the merit so its rather important that you get this right before you can move onto distintion. I know this has not spcifically answerd you questions but that's becasue you need about 10 pages to go into detail about the different tissues and that's you work not mine (and i have NT done it yet :S) .... Good luck :-D
