The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Inulin:** - Inulin is a type of polysaccharide, specifically a fructan, which means it is composed of multiple fructose molecules. - It serves as a reserve food material in certain plants, particularly those in the Compositae family, such as Dahlia tubers. 2. **Understanding Pectin:** - Pectin is classified as a mucopolysaccharide and is primarily found in the cell walls of plants. - During the ripening of fruits, pectin undergoes hydrolysis, breaking down into simpler sugars, which contribute to the sweetness of the fruit. 3. **Identifying the Role of Inulin and Pectin:** - Both inulin and pectin serve as reserve food materials for plants. Inulin acts as a storage carbohydrate, while pectin, upon hydrolysis, provides sugars that can be utilized by the plant. 4. **Evaluating the Options:** - The question asks what inulin and pectin are in plants. The correct option is that both are reserve food materials. - Other options such as waste material, excretory material, or insect-attracting material do not accurately describe the functions of inulin and pectin. 5. **Conclusion:** - Therefore, the correct answer to the question is that inulin and pectin are reserve food materials in plants.
