What is difference between zygote and foetus.?

Question

Answer

The main difference between zygote and Foetus are as follows-
Zygote
1.A zygote is found by the fusion of male and female gametes.
2.It contain only single celll.
3.It beginning with the formation of the body.
Foetus
1.A Foetus is formed by the growth and development of an embryo.
2.It contains many cells.
3.The body Features of developing baby can be indentified.

Answer

The fertilized egg is called zygote whereas the stage of embryo when all body parts can be identified is called foetus. The zygote contains only one cell whereas foetus contains many cells.Zygote is formed by the fusion of ovum and sperm whereas foetus is formed by repeated division of zygote.

Answer

When the male reproductive cell i.e, the sperm comes in contact with the eggs of female reproductive part a new cell is formed called zygote. But foetus is the stage of the embryo in which all the body parts can be identified.

Answer

Zygote:
A zygote is the earliest stage of human development, formed by the fusion of a sperm cell and an egg cell. It is the initial cell that results from fertilization and marks the beginning of a new individual. The zygote contains a complete set of genetic information, half from the mother and half from the father.

Foetus:
A foetus, also spelled fetus, is the later stage of prenatal development in humans. It follows the embryonic stage and begins around the 9th week after fertilization. During this stage, the organs and systems of the body continue to develop and mature until birth.

Differences:

1. Time of Development:
- Zygote: The formation of a zygote occurs immediately after fertilization, when the sperm penetrates the egg.
- Foetus: The foetal stage starts around the 9th week of pregnancy and continues until birth.

2. Size and Structure:
- Zygote: The zygote is a single cell, usually visible to the naked eye, and contains all the genetic material required to develop into a human being.
- Foetus: By the time the foetal stage begins, the embryo has already undergone significant growth and differentiation. The foetus is much larger in size and has recognizable human features.

3. Developmental Milestones:
- Zygote: The zygote undergoes rapid cell division through a process called cleavage. It moves through the fallopian tube towards the uterus, where it implants into the uterine lining.
- Foetus: During the foetal stage, major organs and body systems develop and become functional. The foetus grows in size, and movements such as kicking and sucking thumb become noticeable.

4. Viability:
- Zygote: The zygote is not capable of independent survival outside the womb.
- Foetus: The foetus becomes viable around the 24th week of pregnancy, meaning it has a chance of surviving outside the womb with medical support.

5. Environmental Dependence:
- Zygote: The zygote is completely dependent on the mother's body for nourishment and protection.
- Foetus: While still reliant on the mother, the foetus becomes less dependent on the placenta for nutrition as it develops and its organs mature.

In summary, the zygote is the earliest stage of development after fertilization, while the foetus represents a later stage of prenatal development with more advanced growth and organ development.

Answer

Foetus, embryo and foetus, these terms are mainly used in context to gestation period of viviparous mammals.Zygote is the fertilized egg which is formed when the sperm and egg are fused together. Embryo is the middle stage between zygote and foetus. ... This period is also known as prenatal development.

Answer

Sperm and ovum fuses and fertilization takes place . so this fertilised egg is call zygote. and after few weeks body parts start appearing . more new cells will be formed. at that stage the zygote is called foetus. zygote----> embryo---->foetus.
