The correct Answer is:
To determine how pteridophytes are distinguishable from bryophytes, let's analyze each option provided in the question step by step. ### Step-by-Step Solution: 1. **Understanding Pteridophytes and Bryophytes**: - Pteridophytes (like ferns) and bryophytes (like mosses) are both types of non-flowering plants, classified under cryptogams. However, they have distinct characteristics. 2. **Analyzing the Options**: - **Option (a) Dependent sporophyte**: In bryophytes, the sporophyte is dependent on the gametophyte for nutrition. In pteridophytes, the sporophyte is independent. This option does not distinguish them. - **Option (b) Independent sporophyte**: This is a key feature of pteridophytes. They possess an independent sporophyte, which is not the case for bryophytes. This option could be a distinguishing feature. - **Option (c) Dependent gametophyte**: In bryophytes, the gametophyte is the dominant stage, while in pteridophytes, the gametophyte is independent and smaller. This option does not distinguish them. - **Option (d) No vascular bundles**: Bryophytes lack vascular tissues (xylem and phloem), while pteridophytes have well-developed vascular bundles. This option is a distinguishing feature. 3. **Conclusion**: - The correct answer is **(b) Independent sporophyte**. Pteridophytes are distinguishable from bryophytes primarily because they possess an independent sporophyte, while bryophytes have a dependent sporophyte. ### Final Answer: **(b) Independent sporophyte**
