The major difference between the two is that asexual reproduction produces offspring that are identical copies of the original parent, whereas sexual reproduction produces offspring that are genetically different from either of the parents. This added variability gives offspring produced like this a greater survival advantage in an environment which is constantly changing.
Asexual reproduction mainly occurs in plants. A plant cutting is produced by asexual reproduction, as are strawberry runners and spider plant 'babies'. Plants also reproduced sexually by means of flowers and seeds. Bacteria reproduce asexually and some simpler animals are also capable of this sort of reproduction. A starfish, for example, will regrow into two if cut in half.
Higher animals, including mammals and humans can only reproduce sexually but there is current debate about medicine becoming able to clone humans. Some animals, such as sheep have already been cloned. This is a highly controversial area of research and it is unlikely that people will ever be cloned and so produced by asexual reproduction.
