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 else can I help you with?
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.
Do male or female sperm swim faster in the process of fertilization?
Male sperm typically swim faster than female sperm in the process of fertilization.
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.
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.
Why used the mature pollen grain in pollen germination experiment?
this is because premature pollen grain do not contain the sperm cell for fertilization. only the generative nucleus in mature pollen grain will divide mitosisly to form sperm cell 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?
Meiosis II is completed after entry of sperm.
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?
No. Fertilization is the joining of an egg and sperm.
How does the speed of male sperm compare to female sperm in the process of fertilization?
Male sperm typically swim faster than female sperm in the process of fertilization. This difference in speed can affect which sperm reaches and fertilizes the egg first.
