(i)________ is a heteropolymer present in animals and cellulose is a (ii)__________ present in plants.

Options

A. i-Starch, ii-heteropolymer
B. i-Chitin, ii-heteropolymer
C. i-Starch, ii-homopolymer
D. i-Chitin, ii-homopolymer

Answer

To solve the question, we need to identify the correct terms to fill in the blanks regarding the types of polymers found in animals and plants.

### Step-by-Step Solution:

1. **Identify the Polymer in Animals**:
- The question states that we need to find a heteropolymer present in animals.
- A well-known heteropolymer found in animals is **chitin**.
- Chitin is composed of N-acetyl-D-glucosamine units linked by β(1→4) glycosidic bonds, making it a heteropolymer.

2. **Identify the Polymer in Plants**:
- The second part of the question asks for a polymer present in plants, specifically cellulose.
- Cellulose is a well-known polymer in plants and is classified as a **homopolymer**.
- It is made up of glucose units linked by β(1→4) glycosidic bonds.

3. **Final Answer**:
- Therefore, the complete sentence would be:
- (i) **Chitin** is a heteropolymer present in animals and cellulose is a (ii) **homopolymer** present in plants.

### Final Answer:
(i) Chitin is a heteropolymer present in animals and cellulose is a (ii) homopolymer present in plants.
