The correct Answer is:
To determine how many statements are correct for vascular cryptogams, we will analyze each statement one by one. 1. **First group of evolved terrestrial plants.** - This statement is **incorrect**. The first group of evolved terrestrial plants are bryophytes, which are non-vascular plants. Vascular cryptogams, which include pteridophytes, evolved later. 2. **Main plant body is independent and diploid.** - This statement is **correct**. In vascular cryptogams (specifically pteridophytes), the main plant body is the sporophyte, which is independent and diploid. 3. **Gametophytic plant has true root, stem, and leaf.** - This statement is **incorrect**. The gametophyte in vascular cryptogams is typically small and dependent on the sporophyte. It does not have true roots, stems, or leaves like the sporophyte does. 4. **Sporophylls form distinct compact structures in most of the members.** - This statement is **incorrect**. While some species of pteridophytes (like Selaginella) may have distinct sporophyll structures, this is not true for most members of vascular cryptogams. Now, let’s summarize the correctness of each statement: - Statement (i): Incorrect - Statement (ii): Correct - Statement (iii): Incorrect - Statement (iv): Incorrect Thus, only **one statement** is correct for vascular cryptogams. ### Final Answer: Only **1 statement** is correct for vascular cryptogams. ---
