What does the ovary develop into after fertilization?
Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.
What is formed immediately after fertilization?
After fertilization, the fertilized egg is called zygote or oospore. Following a predetermined mode of development (embryogeny) it gives rise to an embryo, which has the potentiality to form a complete plant. Usually the zygote divides immediately after the first division of primary endosperm nucleus or it divides earlier than the first ...

What happens immediately after the zygote forms?
The zygote enters the uterus in 3 to 5 days. In the uterus, the cells continue to divide, becoming a hollow ball of cells called a blastocyst. The blastocyst implants in the wall of the uterus about 6 days after fertilization.
What happens immediately after fertilization?
The fertilized egg stays in the fallopian tube for about 3 to 4 days. But within 24 hours of being fertilized, it starts dividing fast into many cells. It keeps dividing as it moves slowly through the fallopian tube to the uterus. Its next job is to attach to the lining of uterus.
What happens in the zygote stage?
If a sperm penetrates the egg, fertilization results. Tiny hairlike cilia lining the fallopian tube propel the fertilized egg (zygote) through the tube toward the uterus. The cells of the zygote divide repeatedly as the zygote moves down the fallopian tube to the uterus. The zygote enters the uterus in 3 to 5 days.
Does fertilization happen instantly?
It can take up to 6 days after sex for the sperm and egg to join — if a sperm cell joins with an egg, it's called fertilization. The fertilized egg moves towards your uterus. It gets to your uterus about 3-4 days after fertilization, and it can float around in your uterus for another few days.
What happens to the zygote in the first week?
During the 1st week of human development, the fertilized oocyte divides to form a blastocyst before implantation into the uterine wall.
What are the 3 stages of zygote?
This period is generally divided into three stages: the germinal stage, the embryonic stage, and the fetal stage. The two-week period after conception is called the germinal stage. Conception occurs when a sperm cell combines with an egg cell to form a zygote.
What are the 4 steps of fertilization?
The stages of fertilization can be divided into four processes: 1) sperm preparation, 2) sperm-egg recognition and binding, 3) sperm-egg fusion and 4) fusion of sperm and egg pronuclei and activation of the zygote.
Can I feel when my egg gets fertilized?
Can you feel when an egg gets fertilized? You won't feel when an egg gets fertilized. You also won't feel pregnant after two or three days. But some women can feel implantation, the process in which the fertilized egg travels down the fallopian tube and buries itself deep within the wall of the uterus.
How do you feel after egg is fertilized?
Some women do notice signs and symptoms that implantation has occurred. Signs may include light bleeding, cramping, nausea, bloating, sore breasts, headaches, mood swings, and possibly a change in basal body temperature.
