Reproductive process in which a male sex cell (sperm) unites with a female sex cell (egg). During the process, the chromosomes of the egg and sperm will merge to form a zygote, which will divide to form an embryohttp://www.answers.com/topic/embryo. In humans, sperm travel from the vagina through the uterus to a fallopian tube, where they surround an egg released from an ovary usually two or three days earlier. Once one sperm has fused with the egg cell membrane, the outer layer becomes impenetrable to other sperm.

What is the union of mature egg cell and sperm cell?
Fertilization
Which process requires the sperm and egg cells?
That process is the fertilization. It is the joining of sperm and ovum.
What comes before fertilization in embryology?
Before fertilization in embryology, the egg and sperm undergo a process called gametogenesis where they mature, and then they are released from the ovaries and testes. Once released, they meet during fertilization to form a zygote.
Process of uniting an egg with a sperm?
The process of uniting an egg with a sperm is called fertilization. It occurs when a sperm cell penetrates the outer layer of an egg cell and fuses with the egg's nucleus, forming a zygote. This marks the beginning of a new organism's development.
What are mature male gametes called?
Mature male gametes are called sperm. They are produced in the testes through a process called spermatogenesis. Sperm cells are involved in fertilization when they unite with a female egg cell during sexual reproduction.
Why used the mature pollen grain in pollen germination experiment?
Mature pollen grains are used in pollen germination experiments because they are ready for fertilization. They contain the necessary components for germination, such as starch granules and enzymes, to support pollen tube growth and fertilization of the ovule. Additionally, mature pollen grains have completed the process of meiosis, ensuring they carry the correct number of chromosomes for fertilization.
When a mature egg is removed from the female body for fertilization outside of the body?
This process is called in vitro fertilization (IVF). The mature egg, along with sperm, is fertilized in a laboratory dish. Once fertilization occurs and the embryo(s) develop, they may be transferred back into the uterus for implantation and pregnancy.
When does an oocyte complete meiosis II?
An oocyte completes meiosis II after it is fertilized by a sperm cell. This process results in the formation of a mature ovum (egg) with a haploid set of chromosomes.
What is joined by the process of fertilization?
sperm and egg. the sperm FERTILIZES the egg.
What process by which the egg cell and sperm cell unite during sexual reproduction?
Fertilization is the process by which the egg cell and sperm cell unite during sexual reproduction. It results in the formation of a zygote, which is the initial stage of a new organism.
When sperm joins with an egg the process is called?
Fertilisation is when the sperm cell and the ova fuse together to form a zygote.
What the process of egg cell and sperm cell?
Egg cells are produced in the ovaries through a process called oogenesis, where a specialized cell called a primary oocyte undergoes meiosis to produce a mature egg cell. Sperm cells are produced in the testes through a process called spermatogenesis, where spermatogonia cells differentiate and undergo meiosis to form mature sperm cells. During sexual reproduction, an egg cell and a sperm cell combine during fertilization to form a zygote which has the full complement of chromosomes.
