Polyembryony is mainly found in :-

Options

A. Pteridophyta
B. Bryophyta
C. Gymnosperms
D. Angiosperms

Answer

**Step-by-Step Solution:**

1. **Understanding Polyembryony**: Polyembryony refers to the phenomenon where more than one embryo develops from a single fertilized ovum or within a single seed. This is an important concept in plant reproduction.

2. **Analyzing the Options**:
- **Option 1: Tridophyta**: These are vascular plants that reproduce via spores. They do not typically exhibit polyembryony. Therefore, this option is incorrect.
- **Option 2: Bryophyta**: Bryophytes are non-vascular plants and do not have embryos in the zoological sense. They also do not exhibit polyembryony. Thus, this option is also incorrect.
- **Option 3: Gymnosperms**: Gymnosperms are known for their seeds and often exhibit polyembryony, where multiple embryos can develop from a single fertilized ovum. This makes this option a strong candidate for the correct answer.
- **Option 4: Angiosperms**: Angiosperms have covered ovules and typically do not show polyembryony in the same way as gymnosperms. Therefore, this option is incorrect.

3. **Conclusion**: Based on the analysis, the correct answer is **Option 3: Gymnosperms**, as they are primarily where polyembryony is observed.
