Why do endosperm formation does not occur until fertilization take place?
Endosperm formation is triggered by fertilization because it involves the fusion of the two sperm cells with different nuclei in the embryo sac, leading to the triploid (3n) condition necessary for endosperm development. Without fertilization, the endosperm would not receive the necessary genetic contribution to develop properly and support the growing embryo.
Fertilization of the human egg cell usually occurs in what?
Fertilization of the human egg cell usually occurs in the fallopian tube. After ovulation, the egg is released from the ovary and travels down the fallopian tube towards the uterus. If sperm are present in the fallopian tube at this time, fertilization can occur.
How much time will elapse from fertilization to full implantation?
It typically takes about 6-12 days for the fertilized egg to travel down the fallopian tube and implant into the lining of the uterus after fertilization. Full implantation is usually completed by around day 14 after fertilization.
Why is meiosis essential for sexual reproduction?
Meiosis is essential for sexual reproduction because it allows for genetic variation to occur by producing gametes with half the number of chromosomes. During fertilization, when two gametes combine, a new organism is formed with a unique combination of genetic information from both parents. This genetic diversity is important for the adaptation and evolution of species.
The time between the act of pollination and actual fertilization in the pine is about?
The time between pollination and fertilization in pine trees is typically around 15 months. This allows for the pollen grains to settle on the female cones, germinate, and eventually fertilize the ovules to produce seeds.
What is the time period from fertilization to birth called?
The time period from fertilization to birth is called gestation.
Can fertilization take place in the uterus?
This is a biology question, not a physics question but anyway, yes it can. Most of the time it takes place in the Fallopian tubes, however, it can occur in the upper part of the uterus from time to time.
The joining of the sperm and egg is called?
whenever i do it, they call it rape, but its sexual intercourse

How long is the egg alive after gettin ruptured to get fertilized by the sprem?
An egg can be fertilized by sperm within 12-24 hours after ovulation. Once the egg is released from the ovary, it has a limited window for fertilization before it degenerates. If fertilization does not occur during this time, the egg will disintegrate and be absorbed by the body.
What is the time between fertilization and growth?
embryotic stage
Does the most rapid growth of a human being occur before or after birth?
The trick in this question is the word RATE of growth... Conception starts with the fertilization of a single cell & that doubles every time id divides. It will go from immeasurable to 7-10 pounds in 9 months. At no other time in the life cycle will that "Rate" occur, the answer is before birth.
Is sperm considered as antigen at the time of fertilization?
No, sperm is not considered an antigen at the time of fertilization. Antigens are substances that the immune system recognizes as foreign and can trigger an immune response. Sperm is a normal component of reproduction and does not elicit an immune response during fertilization.
What is the Aztec Sunstone?
it was a stone that told the time due to the pinpoint position of the sun. ;D
What is the period of time between fertilization and birth?
9 months
A mammal's gestation period is the length of time?
Gestation time is the length of time that it takes from fertilization to birth.
When can fertilzation occur in a women?
Fertilization can occur if a woman has unprotected sexual intercourse around the time of ovulation, which typically happens about 14 days before the start of her next menstrual period. Sperm can survive in the female reproductive tract for up to 5 days, so conception can happen even if intercourse took place a few days before ovulation.
