Question

Sequence from fertilization to Gestation.

• A. Zygote – Morula – Blastula – Gastrula
• B. Zygote – Blastula – Morula – Gastrula
• C. Zygote – Morula – Gastrula – Blastula
• D. Zygote – Blastula – Gastrula – Morula

Hint:

The stages of early embryonic development are crucial for the proper formation of tissues and organs in the developing organism.

Answer 1

The Correct Option is A

Step 1: The correct developmental sequence after fertilization is:
1. Zygote: The fertilized egg.
2. Morula: The ball of cells formed after several divisions.
3. Blastula: The stage where the ball of cells forms a hollow cavity.
4. Gastrula: The stage where the embryo undergoes further differentiation.

Conclusion: The correct sequence is Zygote – Morula – Blastula – Gastrula.
