Which of the following groups have haploid plant body

Options

A. Bryophytes
B. Pteriodophytes
C. Gymnosperms
D. Angiosperms

Answer

To determine which group has a haploid plant body, we need to analyze the options provided: bryophytes, pteridophytes, gymnosperms, and angiosperms.

### Step-by-Step Solution:

1. **Understanding Haploid and Diploid**:
- Haploid organisms have one set of chromosomes (n), while diploid organisms have two sets (2n). In plants, the haploid phase is typically represented by the gametophyte, and the diploid phase by the sporophyte.

2. **Analyzing Bryophytes**:
- Bryophytes include mosses and liverworts. In bryophytes, the dominant phase is the gametophyte, which is haploid. This means that the main plant body of bryophytes is haploid.

3. **Analyzing Pteridophytes**:
- Pteridophytes, such as ferns, have a dominant sporophyte phase, which is diploid. They develop from a diploid zygote, indicating that their main plant body is not haploid.

4. **Analyzing Gymnosperms**:
- Gymnosperms, like conifers, also have a diploid sporophyte as the dominant phase. They do not have a haploid plant body.

5. **Analyzing Angiosperms**:
- Angiosperms, or flowering plants, similarly have a diploid sporophyte as the dominant phase. Thus, they do not have a haploid plant body.

6. **Conclusion**:
- From the analysis, it is clear that the only group among the options that has a haploid plant body is **bryophytes**.

### Final Answer:
The group that has a haploid plant body is **bryophytes**.
