    A plant showing vascular tissue but not producing seed belongs to

    A)  gymnosperms     

    B)  pteridophytes

    C)  bryophytes      

    D)  angiosperms.

    Correct Answer: B

    Solution :

    : Pteridophytes are vascular cryptogams i.e., these plants possess vascular tissue (xylem and phloem) no flower, no seed. Vascular system is well developed, i.e., these are the plants in which xylem and phloem were first reported. In xylem, vessels are absent and in phloem, companion cells are absent with some exceptions. Secondary growth is absent except Isoetes. Sporophytic stage dominates over the gametophytic stage.
