what do acrosome contains:   The acrosome is an organelle that develops over the anterior half of the head in the spermatozoa (sperm cells) of many animals including humans. It is a cap-like structure derived from the Golgi apparatus. In Eutherian mammals the acrosome contains digestive enzymes (including hyaluronidase and acrosin).

what is acrosome made up of? :         The acrosome is an organelle that develops over the anterior half of the head in the spermatozoa or sperm cells of many animals. It is a cap-like structure derived from the Golgi apparatus.

its functions:  The function of the acrosome reaction is to help the sperm get through the egg's protective coat and to allow the plasma membranes of the sperm and egg to fuse. This places both haploid nuclei (one from the sperm and one from the egg) into the same cell, where they form the diploid genome of the new organism.
