The process of gastrulation is biologically significant primarily because it results in the formation of which of the following?
Show answer and explanation
Correct answer: The three embryonic germ layers and blastopore
Gastrulation involves massive cellular rearrangements that transform a single-layered blastula into a multi-layered structure. This process establishes the ectoderm, mesoderm, and endoderm — the foundations for all future tissues.
