Where on the flower must pollen be put for fertilisation to take place?
Stigma. the mouth or opening part of carpel in case of flower plants(angio sperms)
When fertilasation happens the nucelues of the sperm must?
When fertilisation happens the nucleus of the sperm cell must release a special chemical which helps it to find a way into the ovum (egg).By Sophie Tyler On The 20/3/2010.
Why must the sex cells have half the chromosome number of the normal body cells?
Otherwise, after fertilisation, the number of chromosomes would be doubled. Then, after each generation, the number of chromosomes would continue to be doubled! One might argue that after fertilisation, meiosis could take place, that is, the halving of the number of chromosomes could take place. It is true, but rare. Some organisms use this method.
Why do you have immunologically privileged sites?
Privileged sites include the uterus, testes and anterior chamber of the eye. Immune tolerance is developed "before" puberty. Sperm develop in the testes during puberty and become immunogenic. A fetus develops in the uterus after puberty as well. They must be protected from the adaptive immune system in order to survive.

Where is an egg usually fertilised by a sperm?
In humans fertilization normally takes place in one of the fallopian tubes. The fertilized egg (ovum) then attaches itself to the uterus where it developes. If it is not fertilized, it will pass from the body through menstruation.Normally in the uterine (fallopian) tubes.In the fallopian tubes
Why are there only a few days in each menstrual cycle when fertilisation can take place?
In order for fertilization to take place, there must be an egg available to be fertilized. So, fertilization can take place between an egg being released, travelling down the fallopian tube, and arriving at the uterus. Once an egg arrives at the uterus, if it is not fertilized, then the body takes steps to get rid of it (menstruation). It only takes a few days for the egg to get to the uterus after being released, so those few days are the only ones when the egg can be fertilized.
Where does fertilization take place in the females body?
Fertilization usually takes place within the fallopian tube, and the zygote begins to divide even as it is being swept toward the uterus. Fertilization does take place in the fallopian tubes, the fertilized egg then travels down to the Uterus wall where it embeds itself. It is extremely dangerous if the egg embeds itself in the fallopian tube or develops at this site.A human egg is fertilized by a human sperm in the fallopian tubes of the female. The fallopian tubes are the passageway between the ovaries and the uterus.After fertilization, the developing baby travels down the tubes into the uterus where it will implant into the wall of uterus, establishing a source of nourishment for the duration of the pregnancy.In rare cases, the baby will not travel to the uterus and attempts to implant within the fallopian tubes, resulting in an ectopic pregnancy. These pregnancies often result in miscarriage and occasionally must be aborted to save the life of the mother. In even more rare situations, the ectopic pregnancy will later dislodge and travel to the uterus and progress normally.
What is the path that the egg cell must travel during ovulation?
first the egg cell is released thru the ovaries. then it comes down the fallopian tubes and into the uterus. it then goes down to the cervix and out the vagina.
Where does fertilization of a oocyte usually occur?
Fallopian Tube
In what part of the female reproductive tract do the sperm cell and the egg cell meet?
The fallopian tube. The fertilized eggs then travels down to the uterus and implants itself there. When a fertilized egg does not make it to the uterus and implants in the fallopian tube, the woman will end up with what's called a tubal pregnancy and must go to surgery right away since it can be fatal.
Where will a sperm met an egg?
The sperm meets the egg inside the fallopian tube inside the woman's body. Once there is sperm inside the vagina, it must travel up through the cervix, up through the uterus, and into the fallopian tubes. Once in the fallopian tube where the egg has been release from the ovary, the sperm can meet up with the egg for fertilization.
Where on the flower must pollen be put for fertilisation to take place?

Do you have to have been pregnant to have your tubes tied?
Call a doctor, as you may have what is called "ectopic" (usually in the fallopian tubes) presentation of the fetus. When this happens, the egg never makes it down to the uterus, and the sperm somehow does its job. This pregnancy must be aborted as it will kill both the mother and fetus, due to damage caused by ectopic presentation. Ectopic defined: Out of Place.
What are some problems with a ectopic pregnancy?
The main problem with ectopic pregnancies is that they must usually be terminated. These happen when the fertilized egg lodges itself somewhere other than in the uterus, most often in the fallopian tubes. If an ectopic pregnancy occurs, then the egg must be removed, and the pregnancy ended. If this course of action is not taken, then the developing fetus may break through the walls of the fallopian tubes, which could put the life of the mother in serious danger.
How many hours must sexual intercourse occur for a sperm cell to fertilize an ovum?
IT takes about 2 hours for a healthy sperm to reach the fallopian tube of the uterus.
What does pelvic pain in women mean?
It is a pain in the pelvis area which usually arises from the reproductive organs of women such as uterus, fallopian tubes, ovaries and vagina. One must consult a gynecologist when experience pelvic pains to determine what cause for that condition.
