The carbohydrates, which on hydrolysis give a large number of molecules of monosaccharides, are called ..............

Explanation

**Step-by-Step Solution:**

1. **Understanding Carbohydrates**: Carbohydrates are biological molecules composed of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1. They are essential for energy storage and supply in living organisms.

2. **Types of Carbohydrates**: Carbohydrates are classified into three main categories:
- **Monosaccharides**: These are the simplest form of carbohydrates, consisting of single sugar molecules (e.g., glucose, fructose).
- **Disaccharides**: These consist of two monosaccharides linked together (e.g., sucrose, lactose).
- **Polysaccharides**: These are complex carbohydrates made up of long chains of monosaccharide units linked together (e.g., starch, glycogen, cellulose).
