Detailed explanation-1: -The sporophytes of Pteridophytes do not produce sex organs.
Detailed explanation-2: -Hence, the correct answer is option B, protonema of moss and prothallus of Dryopteris are gametophytic.
Detailed explanation-3: -The main distinguishing feature of pteridophyta is the presence of vascular tissue for conduction. Indeed, pteridophytes are thought to be the first vascular plants to have evolved on Earth. Xylem and phloem are types of vascular tissue. However, these plants have only primitive xylem and phloem.
Detailed explanation-4: -Answer: Ferns are more advanced than mosses as their cells are organised into tissues and organs, namely roots, stems and leaves. They also have vascular tissue (xylem and phloem) which allows them to grow vertically, as water and nutrients can be transported efficiently throughout the plant.
