A new human individual develops from a cell called __________.

A new human individual develops from a cell called a zygote.

What is a Zygote?

• The zygote is the initial cell formed when a sperm cell from the male and an egg cell (or ovum) from the female fuse during fertilization.
• This single-celled entity contains a full set of chromosomes, half from each parent, and marks the beginning of a new human life.

Development Process:

1. Fertilization: The sperm and egg combine to form the zygote.
2. Cell Division: The zygote undergoes multiple rounds of mitotic division to form a multicellular embryo.
3. Differentiation: Over time, these cells specialize and form different tissues, organs, and systems, eventually leading to the development of a complete human individual.

Conclusion:

The zygote is the first step in human development, starting from the fusion of the male and female gametes. It undergoes various stages of development, including cellular division and differentiation, to form a fully developed individual.
