1. **Understanding Connective Tissue**: Connective tissue is one of the four basic types of tissue in the body, and it serves various functions including support, binding, and protection of other tissues and organs.

2. **Identifying Major Components**: Connective tissue is primarily composed of three main components: cells, fibers, and a gel-like substance known as the extracellular matrix.

3. **Focus on Fibers**: Among the various fibers found in connective tissue, collagen is the most significant. It is a type of fibrous protein that provides strength and support.

4. **Collagen Characteristics**: Collagen fibers are produced by specialized cells called fibroblasts. These fibers are known for their high tensile strength, meaning they can withstand pulling forces without breaking.

5. **Collagen's Role in the Body**: Collagen constitutes a substantial portion of the total body protein in higher vertebrates, accounting for about one-third of it. It is crucial for the structural integrity of various tissues, including tendons, ligaments, and skin.

6. **Conclusion**: Based on the above points, the major constituent of connective tissue is collagen.
