Statement-I : Pteridophytes are first terrestrial plants that possess vascular tissues.
Statement-II : In pteridophytes spore germinates to give rise to inconspicuous small but multicellular, mostly non-photosynthetic leafy gametophytes.

Statement I is correct. Pteridophytes, which include ferns and their relatives, were among the first plants to evolve vascular tissues, such as xylem and phloem, which are important for the transport of water and nutrients. The presence of vascular tissues allowed pteridophytes to grow taller and thrive on land, making them a key evolutionary step in the transition from aquatic to terrestrial life.

Statement II is incorrect. In pteridophytes, the spores germinate to produce prothallus, which are small, multicellular, free-living, primarily photosynthetic thalloid gametophytes.
