Which prenatal stage is characterized by organ formation?

Explanation:
Organ formation happens during the embryonic period when organogenesis occurs. In this stage, the three germ layers—ectoderm, mesoderm, and endoderm—differentiates to form the major organs and body systems. This period lasts roughly from weeks 3 to 8 after conception, laying down the fundamental structures of the brain, heart, lungs, liver, kidneys, and limbs. After this, the fetal period focuses on growth and maturation of those already-formed organs. The germinal period happens earlier and centers on fertilization and implantation, while the neonatal period is after birth.
