The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Pteridophytes**: Pteridophytes are a group of vascular plants that reproduce via spores and do not produce seeds. Common examples include ferns and horsetails. 2. **Analyzing the Statements**: We need to evaluate each statement provided in the question to identify which one is incorrect. 3. **Statement 1**: "Pteridophytes are used for medicinal purposes and as a packing material for trans-shipment of living material." - This statement is incorrect because the use of packing material for trans-shipment is more commonly associated with bryophytes, specifically sphagnum moss, which is used to retain moisture and protect living materials during transport. 4. **Statement 2**: "The leaves in Pteridophytes are small and large." - This statement is correct. Pteridophytes can have a variety of leaf sizes, ranging from small to large. 5. **Statement 3**: "Sporophytes are present in spore mother cells, in which the process of meiosis will take place." - This statement is also correct. In pteridophytes, the sporophyte generation is dominant and contains spore mother cells that undergo meiosis to produce spores. 6. **Statement 4**: "Zygote produces a multicellular dominant phase of Pteridophytes." - This statement is correct as well. The zygote develops into a multicellular sporophyte, which is the dominant phase in the life cycle of pteridophytes. 7. **Conclusion**: The incorrect statement among the options is the first one, which incorrectly attributes the use of packing material to pteridophytes instead of bryophytes. **Final Answer**: The incorrect statement for pteridophytes is the first statement. ---
