The single-celled zygote formed at conception becomes a multiple-celled organism through the
process of cell division known as
O a. mitosis.
O b. canalization.
C. meiosis.
Od. crossing over.



Answer :

Final answer:

Mitosis is the cell division process that helps a single-celled zygote develop into a multi-celled organism through rapid cell division and specialization.


Explanation:

Mitosis is the process of cell division that transforms a single-celled zygote into a multi-celled organism. After fertilization, the zygote undergoes rapid cell division to form a hollow ball of cells called a blastula, which further develops into more specialized cells and eventually different organs and body parts.
