When you pass on, your power of attorney stops working and your executor takes over. Granting a power of attorney and appointing an executor for your estate both authorize another individual to act for you as a legal representative. An executor carries out your wishes for your estate after your death. A power of attorney assigns someone to carry out your wishes while you're alive.
It produces the female egg cells necessary for reproduction, called the ova or oocytes. The system is designed to transport the ova to the site of fertilization. Conception, the fertilization of an egg by a sperm, normally occurs in the fallopian tubes.
The ovary produces egg cells which is the gametes. The egg cell is large in size because it stores nutrients. The egg cell consists of half the number of chromosomes that are found in female body cells. The main function of egg cells is to join with male cells (sperm) for the purpose of reproduction. They also provide food for new cells that are made in the process. After a sperm cell fertilizes an egg cell, it becomes a zygote. The zygote becomes an embryo, and the embryo becomes a fetus if we are discussing mammals.
