After fertilization, the zygote undergoes cleavage, forming a multicellular embryo. The embryo then implants into the uterine lining and develops into a blastocyst. Gastrulation follows, creating the three germ layers that give rise to different tissues and organs.

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.
Do periods occur as normal after an egg is fertilized explain answer?
No, periods do not occur after an egg is fertilized because fertilization of the egg leads to the development of the embryo, which implants in the uterus and eventually grows into a fetus. This process suppresses the shedding of the uterine lining that occurs during menstruation.
Fertilization and development normally occur in?
Fertilization occurs in the fallopian tube when a sperm cell fertilizes an egg cell. After fertilization, the zygote travels to the uterus where it implants into the uterine lining for further development. Embryonic development continues in the uterus until birth.
What would happen if fertilization does not occur?
After puberty, the ovaries release one egg each month alternatively. The sperms enter through the vagina, travel upwards to the oviduct where they encounter the egg. If the egg is fertilized, a zygote is formed. The zygote repeatedly divided to form the embryo. This embryo trickles down to the uterus. On the uterine wall, the embryo gets implanted. The embryo gets nutrition form a special disc shaped tissue towards the uterine wall called the placenta. It contains villi on the embryo's side and provides nourishment and oxygen from the mother's blood. Waste substances such as carbon dioxide and nitrogenous wastes are taken away from the embryo. After the 9 month gestation period, the child is delivered as a result of rhythmic contractions of the uterus.
Where fertilization of human eggs usually occur?
Fertilization of human eggs typically occurs in the fallopian tubes, where the egg is fertilized by sperm to form a zygote. The zygote then travels down the fallopian tube to the uterus, where it implants and develops into an embryo.
What type of division occur to produce an embryo plant from the diploid zygote formed after fertilization?
meiosis

How does animal fertillization occur?
Fertilization in animals can occur inside or outside their body. It involves the sperm to fertilize with egg to form zygote. Then it goes rapid multiplication to form embryo. The embryo then slowly develops into baby.
Do periods occur as normal after an egg is fertilized explain answer?
No, periods do not occur after an egg is fertilized because fertilization of the egg leads to the development of the embryo, which implants in the uterus and eventually grows into a fetus. This process suppresses the shedding of the uterine lining that occurs during menstruation.
What does not occur during the birth process?
Fertilization of the egg does not occur during the birth process. Birth is the process of delivering a baby from the mother's womb, which happens after fertilization, implantation, and gestation have already occurred.
What are all changes that occur from the fertilization of the egg until death referred to as?
The changes that occur from fertilization of the egg until death are referred to as the lifecycle or life cycle. This encompasses all stages of development, growth, reproduction, and eventual death in an organism.
What changes take place after fertilisation?
After fertilization, the zygote is formed, which is the initial stage of a new organism. The zygote undergoes rapid cell division to form an embryo. Changes in gene expression and cell differentiation occur, leading to the development of tissues and organs. Eventually, the embryo develops into a fully formed fetus.
Fertilization and development normally occur in?
Fertilization occurs in the fallopian tube when a sperm cell fertilizes an egg cell. After fertilization, the zygote travels to the uterus where it implants into the uterine lining for further development. Embryonic development continues in the uterus until birth.
What type of fertilization and development occur in the zebrafish?
Zebrafish exhibit external fertilization, where the female releases eggs and the male fertilizes them outside of the body. The embryos develop externally, with the early stages of development taking place outside of the mother's body in the water.
At what age does turner's syndrome occur?
Turner's occurs in situ, usually very early in the development of the embryo.

Why must pollen that fertilizes flowers be from the same species?
Pollen from the same species is required for successful fertilization because the pollen grains need to contain matching genetic information to that of the female reproductive structures in the flower. This ensures compatibility and proper development of the embryo. Pollen from different species would not have the necessary genetic instructions for successful fertilization to occur.
