Which of the following correctly characterizes the plant body of Funaria?

Options

A. Predominantly gametophyte with dependent sporophyte
B. Completely gametophyte
C. Predominantly sporophyte with dependent gametophyte
D. Completely sporophyte

Answer

To determine the correct characterization of the plant body of Funaria, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Funaria**: Funaria is a type of moss, which is part of the Bryophyta group. It is important to know that mosses have a specific life cycle that includes both gametophyte and sporophyte stages.

2. **Life Cycle of Funaria**: Funaria exhibits a haplodiplontic life cycle, which means it alternates between haploid (gametophyte) and diploid (sporophyte) generations. This is a key characteristic of mosses.

3. **Identifying the Main Plant Body**: In Funaria, the main plant body is the gametophyte. The gametophyte is haploid and is responsible for producing gametes (sperm and eggs).

4. **Sporophyte Dependency**: The sporophyte in Funaria is dependent on the gametophyte for its nutrition and support. The sporophyte develops from the zygote formed after fertilization of gametes and remains attached to the gametophyte.

5. **Evaluating the Options**:
- Option A: Predominantly gametophyte with dependent sporophyte.
- Option B: Completely gametophyte.
- Option C: Predominantly sporophyte with dependent gametophyte.
- Option D: Completely sporophyte.

Based on our understanding, the correct characterization is Option A, as the main plant body is indeed the gametophyte, and the sporophyte is dependent on it.

6. **Conclusion**: Therefore, the correct answer is that the plant body of Funaria is predominantly gametophyte with a dependent sporophyte.

### Final Answer:
The correct characterization of the plant body of Funaria is **predominantly gametophyte with dependent sporophyte** (Option A).
