From which embryonic layers is the alimentary canal of an insect derived? (RJ Assit Prof. Ento 2020)

✅Explanation:Alimentary Canal:
-Formed from both the ectoderm and endoderm during embryonic development
-Foregut and hindgut are derived from the ectoderm, while the midgut is derived from the endoderm

📌 Other Options:
-Ectoderm: Outermost embryonic layer, gives rise to external structures and nervous system
-Mesoderm: Middle embryonic layer, gives rise to muscles, circulatory system, and other internal structures

🔑Key Points:
-Insect Embryology: The study of insect development from egg to adult
-Alimentary Canal: A complex system that digests and absorbs nutrients from food
