The sporophyte is attached to the gametophyte in

Options

A. algae
B. fungi
C. bryophytes
D. pteridophytes.

Answer

**Step-by-Step Solution:**

1. **Understanding the Terms:**
- **Sporophyte:** The diploid phase of the plant life cycle that produces spores.
- **Gametophyte:** The haploid phase that produces gametes (sperm and eggs).

2. **Identifying the Relationship:**
- In certain plant groups, the sporophyte is attached to the gametophyte. This attachment is significant for the nutrition and support of the sporophyte.

3. **Focusing on Bryophytes:**
- Bryophytes, which include mosses, liverworts, and hornworts, are the group where the sporophyte remains attached to the gametophyte.
- In bryophytes, the gametophyte is the dominant stage of the life cycle, meaning it is the longer-lived and more prominent phase.

4. **Nutritional Dependence:**
- The sporophyte in bryophytes is dependent on the gametophyte for nutrition. This is because the sporophyte is typically short-lived and requires sustenance from the gametophyte.

5. **Example of Moss:**
- In mosses, after the spore germinates, it forms a protonema, which develops into the leafy gametophyte. The sporophyte grows attached to this gametophyte and relies on it for nutrients.

6. **Conclusion:**
- Therefore, the correct answer to the question is that the sporophyte is attached to the gametophyte in bryophytes.

**Final Answer:**
The sporophyte is attached to the gametophyte in bryophytes.
