Answer: A zygote develops into a multicellular organism through a process called embryogenesis. Embryogenesis is the series of events that occur as a single-celled zygote undergoes cell division and differentiation to form a complex, multicellular organism. This process involves various stages, including cleavage, gastrulation, and organogenesis.
Tl;dr version: The zygote, formed by the fusion of sperm and egg, undergoes a process called embryogenesis to develop into a multicellular organism. This involves stages like cleavage (rapid cell division), gastrulation (formation of germ layers), and organogenesis (development of organs and tissues). The cells differentiate and specialize, ultimately shaping the structure of the organism.
Explanation:
Throughout embryogenesis, cell signaling, gene regulation, and cell-cell interactions play crucial roles in determining the fate of cells and shaping the overall structure of the developing organism. The end result is a multicellular organism with a complex and organized body plan. The specific details of embryogenesis can vary among different organisms, reflecting their unique developmental pathways.
