Why does bread mould grow profusely on a moist slice of bread but not on a dry slice of bread ?
Moisture is necessary for the growth of bread mould. The bread mould grows profusely on moist slice of bread because it provides both moisture and nutrients for growth. The dry slice of bread provides nutrients but no moisture. So, bread mould does not grow on the dry slice of bread.

When you study a slide showing different stages of budding in yeast, you observe the following stages:
I. The bud may get Separated from the parent body and develop into a new individual.
II. The body of the bud develops and gives rise to another baby bud.
III. A bud comes out in any direction from the body of the parent cell.
IV. Thus they may form a colony. The proper sequence of the above stages isScience - Board Papers
