Question

differentiation and specialized cells
during what stage of development does differentiation primarily occur?
choose the correct answer.
gastrula
zygote
blastula

Explanation:

Cell differentiation primarily occurs during the gastrula stage of development. During gastrulation, cells undergo significant reorganization and specialization to form the three germ - layers (ectoderm, mesoderm, and endoderm) which will give rise to different tissues and organs. The zygote is the initial cell formed by fertilization and is undifferentiated. The blastula is a hollow ball of cells but differentiation is more prominent in the gastrula.

Answer:

Gastrula
