Why is it not possible for crystalization to give 100% yield?

Because at some point there is not enough material left in solution to form crystals - it is below saturation

When we talk of crystallisation i.e. purifying a product which will contain impuries. So at the time of crystallisation , maximum pure product will crystallised out but presence of impuries will withheld the pure product so we will not get 100 % yield.

i have just done a piece of coursework involving crystallisation. the answer is this - that crystallisation involves many steps, many filtrations of product, dissolving, recrystallising etc.. and you are almost guaranteed to lose some of the product that you require in these processes. unless you work in a very rich, very professional chemistry company, then the equipment that you use will always lose some product.

Why ask the same question 28 minutes after the first?
