Which of the following correctly displays the sequence of developmental milestones?
A) blastula → gastrula → cleavage
B) cleavage → gastrula → blastula
C) cleavage → blastula → gastrula
D) gastrula → blastula → cleavage

Question

Quizplus · Accepted Answer

The correct sequence of developmental milestones is cleavage, blastula, and gastrula. Cleavage refers to the rapid cell division that occurs after fertilization, resulting in the formation of a hollow ball of cells called the blastula. The blastula then undergoes further differentiation and organization to form the gastrula, which has distinct layers of cells and begins to form structures such as the gut and nervous system. Choice (C) correctly displays the sequence of these milestones.
