How does a fertilized egg give rise to different types of cells?

Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation. Cells in these three layers will give rise to different parts of the organism. The endoderm eventually becomes the gut.

Where does a fertilized egg develops into a baby in the human body?

uterus
(b) A fertilized ovum (in the form of zygote) develops into a baby in the uterus of the female. Explanation: Fertilization is the process in which the nuclei of the egg and sperm unite together in the fallopian tube to form a single-celled zygote. In the fallopian tubes, the sperm and egg meet.

How egg matures and being fertilized in the presence of sperm cell or goes out of the body in the form of blood?

Unless the egg is fertilized by a sperm while in the fallopian tube, the egg leaves the body about 2 weeks later through the uterus — this is menstruation. Blood and tissues from the inner lining of the uterus combine to form the menstrual flow, which in most girls lasts from 3 to 5 days.

How does the Fertilised egg get to the uterus?

Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus. The zygote then burrows into the uterus lining.

Why does Fertilised egg divide?

After a human egg is fertilized, the zygote ‘collapses’ and expands a number of times as the cells multiply. During a collapse, the cells contained in the embryo divide into two groups, allowing two separate embryos to ‘hatch’ from the protective outer layer of what is now called the blastocyst.

What happens to the egg cell after fertilization in plants?

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 happens when an egg is fertilized?

Once fertilized, the egg travels down the fallopian tube toward the womb, or uterus, where it will implant in the uterine wall. Doctors refer to the fertilized egg as an embryo after implantation. Beginning in the ninth week of pregnancy, and until the pregnancy ends, doctors call the developing baby a fetus.

What happens when the egg is fertilized?

A pregnancy starts with fertilization, when a woman’s egg joins with a man’s sperm. Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.

How does the sperm know where the egg is?

So how does the sperm get to the egg? Only 1 in 14 million of the ejaculated sperm will reach the Fallopian tube, but once there the sperm should pick up chemical signals from the egg to help them find their way forward. The sperm finally near the egg and push towards its shell (called the zona pellucida).

Which structure is formed after the fertilization?

Answer: Fertilization occurs when the nucleus of both a sperm and an egg fuse to form a diploid cell, known as zygote.
