2. **Identifying Traits**: In Mendel's experiments with pea plants, he studied various traits. The traits mentioned in the question are:
- Seed color
- Flower color
- Position of flower
- Height of stem

3. **Defining the Term**: The term that encompasses these traits is "characteristics" or "traits". In genetic studies, these are often referred to as "phenotypic traits".

4. **Conclusion**: Therefore, the answer to the question is that seed color, flower color, position of flower, and height of stem are called "traits" or "characters".
