Starch is made up of two polymers : ..................... and ................

Explanation

**Step-by-Step Solution:**

1. **Understanding Starch Composition**: Starch is a polysaccharide that serves as an important carbohydrate source in both plants and animals. It is primarily found in seeds and is a major food source.

2. **Identifying the Polymers**: Starch is composed of two main polymers:
- **Amylose**: This is a linear polymer made up of D-glucose units connected by alpha-1,4-glycosidic linkages.
- **Amylopectin**: This is a branched polymer that also consists of D-glucose units. In addition to the alpha-1,4-glycosidic linkages found in amylose, amylopectin contains alpha-1,6-glycosidic linkages which create its branched structure.
