Question

Quizplus · Accepted Answer

The correct sequence of developmental stages is morula → blastula → gastrula. The morula is the early stage following fertilization and cell division, leading to the formation of the blastula, a hollow ball of cells. The blastula then undergoes gastrulation to form the gastrula, which has differentiated layers of cells.
