Eye lens is formed from:
Correct answer: A. Ectoderm
- A. Ectoderm
- B. Mesoderm
- C. Endoderm
- D. Ectoderm and Mesoderm
Explanation
The eye lens is primarily formed from the ectoderm. During early embryonic development, a portion of the ectoderm on the surface of the head region thickens to form a structure known as the lens placode. This lens placode invaginates to form a lens vesicle, which then differentiates to become the lens of the eye. The lens fibers that constitute the mature lens are derived from the epithelial cells of the lens vesicle.
