The ovary produces the ovum ( the egg cell ) which is the gametes ( sexual reproductive cells ) in the animals and the plants . The ovum is large in size because it stores the nutrients , it is produced in few numbers and it is not mobile ( static ) , It contains half the number of chromosomes that are found in a female body cells .

The egg cell, or ovum (plural ova), is the female reproductive cell in oogamous organisms. The egg cell is typically not capable of active movement, and it is much larger (visible to the naked eye) than the motile sperm cells. When egg and sperm fuse, a diploid cell (the zygote) is formed, which rapidly grows into a new organism.

Here I mention about the mammalian egg cell. Egg cells [1] or Ovum are spherical in shape. The egg cell is the female gamete and it contains almost all the materials which are essential for the entire development of the embryo as it supplies the g...

Mature mammalian egg cells are relatively large, 0.0039 inches in diameter, and contain many proteins and protein precursors. This is because when a sperm cell introduces its genetic information to that of the egg, the egg must respond quickly so that cell division may begin and a new organism may form.

Structure of the Egg. The egg is a biological structure intended by nature for reproduction. It protects and provides a complete diet for the developing embryo, and serves as the principal source of food for the first few days of the chick's life. The egg is also one of the most nutritious and versatile of human foods.

The egg is the organic vessel containing the zygote in which an embryo develops until it can survive on its own; at which point the animal hatches. An egg results from fertilization of an egg cell. Most arthropods, vertebrates (excluding mammals), and mollusks lay eggs, although some, such as scorpions do not.

A complex dialogue exists between egg and sperm. The egg activates the sperm metabolism that is essential for fertilization, and the sperm reciprocates by activating the egg metabolism needed for the onset of development. But before we investigate these aspects of fertilization, we need to consider the structures of the sperm and egg—the two cell types specialized for fertilization.
