How many sperm cells enter the plant ovule?
Plants do not have sperm cells. In plants, fertilization occurs when a pollen grain (containing sperm cells) lands on the stigma of a flower and grows a pollen tube to deliver the sperm cells to the ovule.
What is the entry of the uterus?
The entry of the uterus is called the cervix. It is the narrow, lower part of the uterus that connects to the vagina. The cervix allows menstrual blood to flow out of the uterus during menstruation and also serves as the passageway for sperm to enter the uterus during intercourse.
Does sperm enter the cervix during sex?
This depends upon what you consider "during sex". During ejaculation, the male deposits sperm in the vagina; vaginal contractions pull the sperm towards the cervix which will dilate and allow the sperm to pass into the uterus shortly afterwards.
Is sperm absorbed through blood stream?
No, sperm is not absorbed into the bloodstream. Sperm is typically deposited into the reproductive tract during sexual intercourse and travels through the cervix into the uterus and fallopian tubes to fertilize an egg.
Where the sperm and the egg cell meet?

Can sprem enter the uterus without fertiling an egg?
Yes, sperm can enter the uterus without fertilizing the egg. Just because a woman is fertile doesn't mean she will fall pregnant, there are a LOT of things that can go wrong to prevent pregnancy such as poor sperm quality or there not being enough sperm reaching the egg to fertilize it.
Why does the sperm not go through the uterus on the way out of the mans body?
During ejaculation, sperm travel through the vas deferens, which is a different pathway than the uterus. The vas deferens carries the sperm from the testes to the urethra, where they are ejaculated out of the penis. The sperm do not enter the uterus because they do not need to in order to fertilize an egg.
If the vagina is like a hallway what structure acts as a door to allow sperm to enter?
The cervix acts as a door between the vagina and the uterus. It opens and thins during ovulation to allow sperm to enter the uterus and potentially fertilize an egg.
What is the biological requirement for reproduction for male and female?
The male produces sperm cells, which carry his genes. The sperm cell meets an egg cell from the female which carries her genes. The sperm cell penetrates the egg's outer layer. This is called "fertilizing" the egg. Normally, the outer layer of the fertilized cell thickens, so no more sperm cells can enter it. The fertilized egg then travels to the woman's uterus, where it attaches to the wall of the uterus and ultimately develops into a fetus.
How long does the sperm cells live in the uterus of a woman?
Sperm cells can live in a woman's uterus for up to 5 days, though the average is about 3-4 days. However, the lifespan of sperm can vary depending on factors such as cervical mucus quality and overall vaginal environment.
Does fertilization take place in the uterus?
The uterus is normally where fertilization takes place; the ovum drops down through the fallopian tubes into the uterus, the sperm enter the uterus by means of sexual intercourse, and the sperm and the ovum meet there. There are also cases in which an enterprising sperm cell manages to swim up a fallopian tube and meets an ovum that is on the way down, which can result in an ectopic pregnancy, which is a dangrous situation.
How many sperm cells enter the plant ovule?
Plants do not have sperm cells. In plants, fertilization occurs when a pollen grain (containing sperm cells) lands on the stigma of a flower and grows a pollen tube to deliver the sperm cells to the ovule.
