Question

Why are the Bryophytes not included under Pteridophyta?

• A. Presence of vascular tissue
• B. Sporophyte being dominant in their life-cycle
• C. Presence of roots
• D. Absence of vascular tissue and the dominant phase in the life-cycle being the gametophyte and not the sporophyte

Answer 1

The correct option is D Absence of vascular tissue and the dominant phase in the life-cycle being the gametophyte and not the sporophyte

Bryophytes are embryophytes that are non-vascular i.e., they have no xylem and phloem. Pteridophytes are vascular plants i.e., plants with xylem and phloem, that reproduce and disperse via spores. The dominant phase in Bryophyte is gametophyte, while the dominant phase in Pteridophyte is sporophyte. Bryophytes have no true roots, while Pteridophyte have true roots. Bryophytes have no vascular tissues, while Pteridophytes have vascular tissues. Hence the correct option is D.
