Gametophytic plant body is non-vascular in

Options

A. Algae and liverworts
B. Mosses and fems
C. Gymnosperms and angiosperms
D. All of these

Answer

To answer the question "Gametophytic plant body is non-vascular in," we will analyze the characteristics of different plant groups and their gametophytic structures step by step.

### Step-by-Step Solution:

1. **Understanding Gametophytes**:
- Gametophytes are the haploid phase in the plant life cycle that produces gametes (sperm and eggs). They are essential for sexual reproduction in plants.

2. **Defining Non-Vascular Plants**:
- Non-vascular plants are those that do not have specialized tissues (xylem and phloem) for the transport of water and nutrients. They typically rely on diffusion for these processes.

3. **Identifying Non-Vascular Plant Groups**:
- The main groups of non-vascular plants include:
- **Bryophytes**: This group includes mosses and liverworts. They are entirely non-vascular and have a dominant gametophyte stage.
- **Algae**: Although not classified strictly as plants, many algae also have a gametophytic phase and are non-vascular.

4. **Examining Vascular Plant Groups**:
- Vascular plants include:
- **Pteridophytes**: These include ferns, which have a vascular sporophyte but a non-vascular gametophyte.
- **Gymnosperms and Angiosperms**: Both groups are vascular, but their gametophyte structures (pollen grains and ovules) are non-vascular.

5. **Conclusion**:
- Based on the analysis:
- Algae and liverworts are non-vascular and gametophytic.
- Mosses (a type of bryophyte) are also non-vascular and gametophytic.
- Ferns (pteridophytes) have non-vascular gametophytes.
- Gymnosperms and angiosperms have non-vascular gametophytes.
- Therefore, the statement "Gametophytic plant body is non-vascular in" applies to all the mentioned groups.

### Final Answer:
The correct option is that the gametophytic plant body is non-vascular in all of the following: algae, liverworts, mosses, ferns, gymnosperms, and angiosperms.
