The correct Answer is:
To solve the question, we need to evaluate each of the provided statements regarding their accuracy. Let's analyze them one by one: 1. **Cutin is a fatty acid polymer.** - Cutin is indeed a polymer made up of fatty acids, specifically hydroxy fatty acids. It forms a protective layer on the surfaces of leaves and stems. Therefore, this statement is **correct**. 2. **Starch is a glucose polymer.** - Starch is composed of two components: amylose and amylopectin, both of which are polymers of glucose. Amylose consists of linear chains of glucose units linked by α-1,4-glycosidic bonds, while amylopectin has branched chains with both α-1,4 and α-1,6 linkages. Thus, this statement is also **correct**. 3. **Sucrose is a monosaccharide.** - This statement is **incorrect**. Sucrose is a disaccharide, formed from one glucose molecule and one fructose molecule. Therefore, this statement is **wrong**. 4. **Maltose is a polymer of fructose.** - This statement is also **incorrect**. Maltose is a disaccharide composed of two glucose molecules linked together. Therefore, this statement is **wrong**. Now, we can summarize our findings: - Statement 1: Correct - Statement 2: Correct - Statement 3: Incorrect - Statement 4: Incorrect Thus, the correct answers are statements 1 and 2. ### Final Answer: The correct statements are: 1. Cutin is a fatty acid polymer. (Correct) 2. Starch is a glucose polymer. (Correct) 3. Sucrose is monosaccharide. (Incorrect) 4. Maltose is polymer of fructose. (Incorrect)
