Answer: Forming the embryo and providing DNA.
Explanation: The egg is a cell that is used to reproduce. It is the very beginning of what will become the embryo and eventually the baby. The sperm fertilizes the egg and contributes 50% of the embryo DNA to the ova (the other 50% of DNA comes from the egg, however sperm only contributes DNA to the egg during the fertilization process whereas the egg has a much more important role). The sperm and egg meet, the egg becomes fertilized and loaded with the DNA it needs to form. The egg provides nutrients needed for the embryo to grow until it is fully gestated.
