The main plant body of bryophyte is:-

Options

A. Haploid
B. Diploid
C. Haplo-diploid
D. Diplo-haploid

Answer

**Step-by-Step Solution:**

1. **Understand Bryophytes**: Bryophytes are non-vascular plants, which include mosses, liverworts, and hornworts. They are characterized by their simple structure and lack of vascular tissues.

2. **Identify the Main Plant Body**: In bryophytes, the main plant body is the part that is independent and photosynthetic. This is crucial to understanding their life cycle.

3. **Life Cycle of Bryophytes**: Bryophytes exhibit a dominant gametophyte stage in their life cycle. The gametophyte is the haploid phase, which means it has only one set of chromosomes.

4. **Gametophyte Characteristics**: The gametophyte is the main plant body of bryophytes. It is responsible for photosynthesis and is independent of the sporophyte, which is the diploid phase.

5. **Sporophyte Generation**: The sporophyte generation arises from the fertilization of gametes produced by the gametophyte. The sporophyte is diploid and dependent on the gametophyte for nutrition.

6. **Conclusion**: Since the main plant body of bryophytes is the gametophyte, which is haploid, the correct answer to the question is that the main plant body of bryophytes is haploid.

**Final Answer**: The main plant body of bryophyte is haploid.
