In which group will you place a plant which reproduces by means of spores, has vascular supply, and dipoid sporophytic phase as dominant phase?

Options

A. Bryophyta
B. Pteridophyta
C. Gymnosperm
D. Angiosperm

Answer

To determine the group in which to place a plant that reproduces by means of spores, has a vascular supply, and has a diploid sporophytic phase as the dominant phase, we can follow these steps:

### Step 1: Identify the Characteristics of the Plant
- The plant reproduces by means of spores.
- It has a vascular supply (xylem and phloem).
- The diploid sporophytic phase is the dominant phase.

### Step 2: Analyze the Groups of Plants
- **Bryophyta (Mosses)**: These plants do not have a vascular supply (no xylem and phloem). They reproduce by spores, but the dominant phase is the haploid gametophyte, not the diploid sporophyte. Therefore, this group is not correct.

- **Gymnosperms**: These are seed-bearing plants that do not reproduce by spores. They have a dominant sporophyte phase, but since they reproduce by seeds, they do not fit the criteria. Thus, this group is also incorrect.

- **Angiosperms**: Similar to gymnosperms, angiosperms are also seed-bearing plants and do not reproduce by spores. They have a dominant sporophyte phase, but again, they do not fit the criteria. This group is incorrect as well.

- **Pteridophyta (Ferns)**: This group includes plants that reproduce by spores, have a well-developed vascular system (xylem and phloem), and have a dominant diploid sporophyte phase. Therefore, this group fits all the criteria given in the question.

### Step 3: Conclusion
Based on the analysis, the correct group to place the plant is **Pteridophyta**.
