List out the Difference between Zygote and Foetus

Q. List out the difference between Zygote and Foetus

Zygote and foetus are two distinct terms that refer to the developmental periods that take place inside the uterus or womb of the mother. Both terms refer to the same thing.

• The zygote is created in the body of the female when there is a fusion between the male gamete (sperm) and the female gamete. This occurs during the process of fertilisation (egg)
• The first stage in the development of a baby is called the zygote. A fertilised ovum is another name for an egg that has been fertilised by the union of a sperm cell and an egg cell
• After the first stage (zygote formation), the second stage (blastocystis) begins
• In the third embryonic stage, the brain, heart, and spinal cord form. Arms and legs develop
• The term “foetus” refers to the final product of foetal development. At the beginning of the 11th week of pregnancy, an embryo is referred to as a foetus for the first time
• The foetus is the name given to the developing organism at the stage following the formation of the embryo when it begins to grow more
