How does a fertilized egg become an organism made of many cells?

Answer 1

Cell differentiation.

DNA contains the code to form any type of cell in the human body. At first, the cell just replicates everything, then it starts to differentiate. Some parts of the code become inactive and other parts become active. This is how it goes from a bundle of cells to creating bones, liver, lungs, heart, brain, etc.

Answer 2

After fertilization occurs, the zygote undergoes multiple rounds of cell division through a process called mitosis. These divisions give rise to a multicellular structure called a blastocyst. The blastocyst then undergoes further differentiation and growth to eventually form an organism composed of many specialized cells.

Answer 3

from being one cell, the cell automatically tells itself to multiply and divide itself.

Edited answer:

By the process of growth and differentiation called embryogenesis

Answer 5

Differentiation begins to occur. This allows some cells to become skin cells or hair cells or muscle cells, forming an organism with many different parts.

Answer 6

They grow because they multiply.
