If in Funaria, the leaf has eight chromosomes, the structrue with 16 chromosomes will be

Options

A. Protonema
B. Rhizoids
C. Capsule and seta
D. All above

Answer

To solve the question regarding Funaria and its chromosome number, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chromosome Number in Funaria**:
- The question states that the leaf of Funaria has 8 chromosomes. This is the haploid (n) number of chromosomes.

2. **Determine the Diploid Number**:
- In plants, the diploid (2n) number is typically double the haploid number. Therefore, if the haploid number (n) is 8, the diploid number (2n) will be:
\[ 2n = 2 \times 8 = 16 \]

3. **Identify the Structure with 16 Chromosomes**:
- The structure that contains the diploid number of chromosomes (16 in this case) is typically the sporophyte generation in the plant life cycle. In Funaria, the sporophyte is the structure that develops from the fertilization of gametes.

4. **Conclusion**:
- Therefore, the structure with 16 chromosomes in Funaria is the **sporophyte**.

### Final Answer:
The structure with 16 chromosomes in Funaria is the **sporophyte**.
