Lens of eye develops from

Options

A. Endoderm
B. Ectoderm and mesoderm
C. Ectoderm
D. Mesoderm

Answer

**Step-by-Step Solution:**

1. **Understanding Germ Layers**: In human development, there are three primary germ layers: ectoderm, mesoderm, and endoderm. Each of these layers gives rise to different tissues and organs in the body.

2. **Identifying the Germ Layers**:
- **Endoderm**: This layer primarily forms the epithelial lining of the digestive and respiratory tracts, as well as organs like the liver and thyroid gland.
- **Mesoderm**: This layer gives rise to structures such as the skeletal system, circulatory system, and dermis of the skin.
- **Ectoderm**: This layer is responsible for forming the epidermis of the skin, tooth enamel, and certain glands.

3. **Focusing on the Eye**: The question specifically asks about the lens of the eye. We need to determine which germ layer is responsible for its development.

4. **Identifying the Correct Germ Layer for the Lens**:
- The lens of the eye, along with the cornea, develops from the ectoderm. This is a key point in embryonic development.

5. **Conclusion**: Therefore, the lens of the eye develops from the ectoderm.

**Final Answer**: The lens of the eye develops from the ectoderm.
