What occurs when sperm cell unites with a egg cell?
When sperm reach an egg, there is a competition to get into the egg first. Since sperm travel in groups, theres a lot of competition. Once a sperm has penetrated the membrane, the membrane hardens, blocking the rest of the sperm out. Once inside, the sperm releases its genetic material, and the egg cell divides, and will continue so until a new baby is born.
Describe how you were able to tell by observation when a sea urchin egg was fertilized?
after an egg is penetrated by a sperm, the egg and sperm nuclei fuse to form a single nucleus. within 2- 5 minutes after sperm penetration, a fertilization membrane forms beneath the jell coat to prevent the entry of additional sperm.
What is joining of an egg and a sperm?
The joining of an egg and a spermatazoan (sperm) is called fertilization.
What is the joining of a sperm and an egg?
The joining of an egg and a spermatazoan (sperm) is called fertilization.
Why do sperm cells need a tail but egg cells do not?
Sperm cells need a tail to get food or energy while the egg isnt alive yet to need emergy......?
When a sperm and egg join what is the single cell called?
The single cell formed when a sperm fertilizes an egg is called a zygote.
What is the process when sperm joining the egg called?
FERTILIZATION
After a sperm fertilizes and egg what is the egg called?
A fertalized egg is a zygote.
When a sperm unites with an egg what is the fertilized egg?
The gametes, or "sex cells" - the sperm and ovum (egg) - become the fertilized egg (zygote) when they fuse.
What are the egg and the sperm cells called?
The cell formed after fertilization by sperm and egg is called a zygote. A zygote is a diploid cell, meaning a cell that has two sets of chromosomes (one from egg, one from sperm).
What are egg and sperm cells called?
They are called sex cells, or to be more scientific, gametes.
How do you know if the sperm got inside the egg?
If fertilization has occurred, the sperm will have successfully penetrated the outer membrane of the egg to release its genetic material. This typically happens within the fallopian tube shortly after sexual intercourse. The fertilized egg will then start dividing and developing into an embryo.
