Why do sperm cells fail to unite with egg cells?
because the sperm cells fail to find the egg cells or the sperm isn't good to unite with the egg
How many sperm cells fertilized the egg cells?
one
How many sperm can be fertilized an ovum?
The exact number of egg cells that can be fertilized is exactly the same as the number of egg cells that are available. For example, in a salmon, about 7,000,000. In a human, normally one, occasionally two to three, rarely up to five and very, very rarely up to seven. Just because they 'can be' fertilized though does not mean that they 'will be' fertilized!
What 2 cells created you?
A sperm and an egg.
Is the union of egg and sperm mitosis or meiosis?
Neither. The union of a sperm and egg is called fertilization. Both sperm and egg cells are sex cells that are produced through meiosis.
What is the function of the egg cell and sperm cell?
the sperm cells have to swim to the ovum and then fertilise it. and the egg cells have to reproduvce the offspring
Why the egg and sperm meet?
Because the sperm will die if it doesn't fertilise the egg. Survival at its basics.
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.
Which part of a plant cell swims towards the egg to fertilise it?
sperm
Where does the egg and the sperm fertilise?

Does the egg select the sperm or does an egg always become fertilized in the presence of sperm?
The sperm has to fertilise the egg. sometimes one gets through, others they don't. Obviously if the sperm gets through then the woman is pregnant
How does the sperm and egg cell meet in frogs?
Frogs use external fertilisation, this means that the female frog lays thousands of eggs, but then the male sprays sperm on the offspring to fertilise it. So basically the sperm cell and egg cell meet when the male sprays his sperm cells over the eggs.
How long does the tail of sperm remain attached to the head?
The tail of a sperm remains with the head until the sperm goes into the egg to fertilise it.
