The yolk sac arises from the ovum to nourish the embryo.
When the ovum is fertilized by the sperm, it is called fertilization. This process involves the fusion of genetic material from the sperm and the egg to form a zygote, which will eventually develop into an embryo.

The egg or ovum is more correctly called an oocyte. It is referred to as an oocyte until it is fertilized by sperm, after which it becomes an embryo.
ovum isalways haploid and when a haploid sperm fertilize it the embryo become diploid
A blastoderm is a germination point in an ovum from which the embryo develops.
The correct term for a fertilised ova is an embryo.
Sperm and ovum.
Typically, only one sperm fertilizes an ovum to form a zygote. Multiple sperm attempting to fertilize the ovum can lead to abnormalities in the resulting embryo.
After fertilization, the uterus lining provides nourishment and protection for the fertilized ovum. The ovum implants in the uterus lining, where it receives nutrients and support for development into an embryo.
A chicken egg is a round or oval body laid by the female chicken, which consists of an ovum surrounded by layers of membranes and an outer casing, which acts to nourish and protect a developing embryo and its nutrient reserves.
The gamete produced by the ovaries is called the ovum, or egg cell. Each ovum is released during the process of ovulation and can be fertilized by a sperm cell to form a zygote, which may develop into an embryo. In females, typically one ovum is released per menstrual cycle.
The cell that is ovulated is called an egg cell, also known as an oocyte. It is released from the ovary during ovulation and can be fertilized by sperm to form an embryo.
