Question
Which of the following has the correct order of development in human? a. Embryo- Zygote- Gamete- Foetus b. Zygote- Embryo- Gamete- Foetus c. Gamete- Zygote- Embryo- Foetus d. Gamete- Embryo- Zygote- Foetus
Correct Answer
Option C is the correct answer.
Detailed Explanation
The correct developmental order begins with gametes (sperm and egg). Their fusion forms a zygote. The zygote undergoes cleavage to become an embryo. After the embryonic period (up to 8 weeks), the developing human is called a fetus until birth. So, Gamete -> Zygote -> Embryo -> Foetus.
Hint
It starts with sex cells, then the single cell, then the early developing form, then the later stage.
