The zygote is the initial stage in baby development. It is also known as a fertilized ovum formed from the union of the sperm cell and the egg cell. Foetus refers to the final stage in baby development. An embryo is termed as the foetus in the beginning in the 11th week of pregnancy.

Is a zygote a baby?
When the single sperm enters the egg, conception occurs. The combined sperm and egg is called a zygote. The zygote contains all of the genetic information (DNA) needed to become a baby. ... The embryo is what will develop into your baby.
When does a zygote become an embryo?
The embryonic period of development lasts from two weeks after conception through the eighth week, during which time the organism is known as an embryo. 1 At the ninth week post-conception, the fetal period begins.
What is the difference between embryo?
An embryo is the young multicellular organism formed before it emerges from the seed.
...
Difference between embryo and seed.
| Embryo | Seed |
|---|---|
| It is formed by the fusion of sperm and nucleus. | It is a ripened ovule formed after fertilization. |
| An embryo is a specific part of the seed. | Seed comprises the embryo & endosperm. |
When is a fetus a baby legally?
According to them, the fetus which is 16 weeks can be regarded as human being because of ensoulment. It follows from this that one is authorized to refer to fetus which is 16 weeks or more as human being.
Does life begin at fertilization?
Life Begins at Fertilization with the Embryo's Conception. "Development of the embryo begins at Stage 1 when a sperm fertilizes an oocyte and together they form a zygote." "Human development begins after the union of male and female gametes or germ cells during a process known as fertilization (conception).
Is an embryo alive?
This means that the embryo has the same nature—it is the same kind of entity, a whole human organism—from fertilization forward; there is only a difference in degree of maturation between any of the stages in the development of the living being.
When does an embryo have a heartbeat?
Hearing a baby's heartbeat for the first time is an exciting milestone for new parents-to-be. A fetal heartbeat may first be detected by a vaginal ultrasound as early as 5 1/2 to 6 weeks after gestation. That's when a fetal pole, the first visible sign of a developing embryo, can sometimes be seen.
What is the best embryo grade?
Grade 1 through 2.5 embryos seem to have the greatest potential for developing to the blastocyst stage. However, a grade 3 embryo may also be of good quality if its appearance can be explained by asynchronous cell division rather than by poor development.
What are the stages of a fetus?
The process of prenatal development occurs in three main stages. The first two weeks after conception are known as the germinal stage, the third through the eighth week is known as the embryonic period, and the time from the ninth week until birth is known as the fetal period.
What week does the placenta form?
In weeks 4 to 5 of early pregnancy, the blastocyst grows and develops within the lining of the womb. The outer cells reach out to form links with the mother's blood supply. After some time, they will form the placenta (afterbirth).
How is embryo formed?
Some of the cells from the placenta develop into an outer layer of membranes (chorion) around the developing blastocyst. Other cells develop into an inner layer of membranes (amnion), which form the amniotic sac. When the sac is formed (by about day 10 to 12), the blastocyst is considered an embryo.
