These small motile gametes fertilize ovum?
Sperm are the small motile gametes that fertilize the ovum (egg) during sexual reproduction in many organisms. They typically have a whip-like tail (flagellum) that helps them swim towards the egg for fertilization to occur.
How many sperm cell are needed for fertilization?
Only one sperm is required to fertilize an egg. One is both necessary and sufficient in order for an egg to be fertilized. But in order to be confident that one will make it, you need a certain minimum sperm count.
How many hours must sexual intercourse occur for a sperm cell to fertilize an ovum?
On average, sperm can live inside a female body for up to 5 days. So, fertilization can happen if sexual intercourse occurs within the 5-day window leading up to ovulation. The actual time duration of intercourse needed for fertilization is typically quite short, usually a matter of minutes.
Do fish have sperm and how does their reproductive process differ from other animals?
Yes, fish do have sperm. The reproductive process of fish differs from other animals in that most fish lay eggs externally, which are then fertilized by the sperm released by the male fish. This is known as external fertilization, whereas many other animals have internal fertilization.
What happens when the pollen tube joins the ovule?
If The Pollen Tube Joins The Ovules They Will Have Fertilization And At The End After The Ovules Will Become The Seeds It Is One Or Many Seeds
Why is necessary to release so many sperm at a time?
to ensure the fertilization of the egg with the mostcompatible sperm
What happened doing fertilize?
If your question is what happens during fertilization? the answer varies. If your are speaking about sexual reproduction then fertilization occurs when the sperm and egg combine. Basically the first sperm to get to the egg keeps it. The egg hardens to keep excess sperm from entering. (of course some errors can occur which will lead to defects, twins, triplets, etc.) There are many other phases to the reproduction process but fertilization is basically when the egg and sperm combine.
Why so many sperms are needed for fertilization to occur?
Actually, it only takes one sperm to fertilize the egg, but the problem is the journey to the egg. The male ejaculates so many sperm because most of them die on the way there, the lucky one that gets there cause the fertilization.
What does a acrosame do?
There is no such thing as an acrosame. An acrosome, however, is a cap-like structure on the head of sperm cells in many animals. The acrosome contains digestive enzymes which break down the outer membrane of the female egg to permit the sperm cell to penetrate (fertilize) the egg.
How many chromosomes does a sperm cell have prior to fertilization?
23
How many sperm unite with the egg what do you call this?
The union is called fertilization and only one sperm can fertilize an egg.
How many sperm unite with egg what do you call the union?
The union is called fertilization and only one sperm can fertilize an egg.
How many sperm unite with the egg what do you call this union?
The union is called fertilization and only one sperm can fertilize an egg.
Are all eggs fertilized in external fertilization?
No, in external fertilization, not all eggs are fertilized. The eggs are released into the environment and must be externally fertilized by sperm for fertilization to occur. Many eggs may not encounter sperm and therefore will remain unfertilized.
How many days does it take sperm n egg to fertization?
Fertilization typically occurs within 24 hours of the egg being released from the ovary. Once sperm enters the female reproductive tract, it can survive for up to 5 days waiting for the egg to be released. So, fertilization can occur within a window of 1-6 days after intercourse.
Where does external fertilization occurs ternal fertilization occurs?
External fertilization typically occurs in aquatic environments, where eggs and sperm are released into the water. This method is common in many fish and amphibian species, allowing sperm to swim to the eggs for fertilization. In contrast, internal fertilization occurs inside the body of the female, common in terrestrial animals like mammals and reptiles, where sperm fertilizes the egg within the reproductive tract.
Does internal fertilization need a medium such as water?
No, internal fertilization does not require a medium like water. In this reproductive process, sperm fertilizes an egg within the female's body, which allows for fertilization to occur in a more controlled environment. This adaptation is common in many terrestrial animals, including mammals, where it enables the development of embryos in a protective setting.
