Sporophyte with indefinite growth occurs in:-

Options

A. Liver worts
B. Horn worts
C. Moss
D. Fern

Answer

To solve the question "Sporophyte with indefinite growth occurs in:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Sporophyte**:
- The sporophyte is the diploid phase in the life cycle of plants, which produces spores. It is important to know that different groups of plants exhibit different growth patterns in their sporophytes.

2. **Identify the Groups of Plants**:
- The question mentions four groups: liverworts, hornworts, mosses, and ferns. We need to analyze each group to determine their sporophyte growth characteristics.

3. **Analyze Liverworts**:
- Liverworts are a type of bryophyte. Their sporophytes typically exhibit definite growth, meaning they grow to a certain size and do not continue to grow indefinitely.

4. **Analyze Hornworts**:
- Hornworts, also a type of bryophyte, are known for having sporophytes that show indefinite growth. This means that their sporophytes can continue to grow throughout their life due to the presence of a basal or intercalary meristem, which allows for the continuous production of new sporangial tissue.

5. **Analyze Mosses**:
- Mosses, another group of bryophytes, also exhibit definite growth in their sporophytes, similar to liverworts. They do not have the capacity for indefinite growth.

6. **Analyze Ferns**:
- Ferns are vascular plants and their sporophytes also show definite growth. They grow to a certain size and do not continue to grow indefinitely like hornworts.

7. **Conclusion**:
- After analyzing all the groups, we find that the only group where the sporophyte exhibits indefinite growth is hornworts. Therefore, the correct answer to the question is hornworts.

### Final Answer:
The sporophyte with indefinite growth occurs in **hornworts**.
