Why the female needs a thick uteras lining fertilization does occur?

the uterine lining thickens to allow an embryo to implant. The reason it thickens is to allow room for blood vessels to supply the area with oxygenated blood. if a child doesn't implant, then it's just superfluous preparation, and the cycle starts again.

What are the fallopian tubes?
It is a thin tube connecting the ovaries with the uterus, it is the site of fertilization i.e. the fusion of male and female gamete.It is the part of female reproductive system in which sperm and egg intract to each other (fertilization).
Why do plants need pollination to occur?
About 65 percent of flowering plants require insects for pollination to complete seed production. About 20 percent of all insects feed on the nectar of flowers as part of their life cycles. The plant and insect world are codependent for survival.
What does fertilization of plant gametes produce?
whe fertilization occurs a fertilized egg , or zygoto is produced.
Is the sacrum and coccyx shorter and less curved in the female than in males?
yes. sacral curve in female is less curve in male. female needs to keep the tailbone posterior in order to increase the size of pelvic cavity to acccommate fetus.
A large concentration of mitochondria are present in which section of a sperm cell?
A large concentration of mitochondria are present in the tail section of the sperm. The mitochondria are the energy components, and the tail needs the energy for it's journey to fertilization.
Why does a female no longer needs thick uterus lining if fertilization doesn't occurs?
The thick lining is prepared by the nature,so that implantation of the zygote should be possible. If there is no fertilization, then this lining is shed away. You have fresh lining for the next month. After all generation next is very much important for the nature.
Is external fertilization sexual or asexual?
Well, there is fertilization in sexual reproduction, but there is not fertilization in asexual because the female reproductive system needs help with the male reproductive system through sex. Without sex, it is asexual. Females need the males sperm in order to fertilize the baby or plant.
What is flower fertililzation?
Flower fertilization is when the pollen gets into the female parts of the flower and the seeds start to form. Each ovule or egg needs some pollen to form a seed.
What classes of vertebrates use external fertilization?
Two classes:Fish and Reptileswhat is interior and exterior fertilization?Internal fertilization is when the sperm is directly deposited into the female, who produces eggs and fertilizes them in her body. External fertilization is when the sperm and eggs are released outside of the body and meet outside of the body, not like how chithra described. Birds do not have external fertilization, the fertilization still occurs in the body, they just do not produce live young.Examples of external fertilization are in plants like moss or algae, where the sperm and eggs meet outside of the parent's body and produce a zygote, which then grows into a mature plant. External fertilization in animals are usually in marine organisms, like sponges, because the sperm needs to swim in water to meet the egg.-Your Welcome

What are the similarities of internal external fertilization?
Internal fertilization takes place inside the body of the female. It is necessary for animals which live on land (terrestrial animals) and is retained by aquatic animals descended form terrestrial ancestors eg whales and dolphins. External fertilization takes place outside the body of the female. It usually takes place in water, usually the environment in which the animal lives eg fish and amphibians. This is because eggs and sperm would dry out and die if they are not kept wet. Internal fertilization is more certain than external fertilization so fewer eggs need to be produced. After internal fertilization eggs can be protected and fed while developing inside the mother's body. After external fertilization the eggs are potentially exposed to predators and so must either be produced in very large numbers or protected by the parents or both.
What is the process of pollination to fertilization?
Pollination when the pollen is taken from one plant to another by wind, water,insect or self pollinated. Then fertilization when the pollen is transferred from the male part of the flower to the female part(the ovule) which grows the seed and then germination the actual growth of the seed-germination needs moisture, warmth and oxygen.
