In Pteridophytes, the MAIN plant body is:
AMycelium
BGametophyte (as in bryophytes)
CSPOROPHYTE — differentiated into true root, stem and leaves with well-developed vascular tissues (xylem and phloem)
DThallus only
Answer & Solution
Correct answer: C. SPOROPHYTE — differentiated into true root, stem and leaves with well-developed vascular tissues (xylem and phloem)
Pteridophytes show the FIRST switch to a dominant sporophytic plant body with true roots/stem/leaves AND vascular tissues (xylem/phloem). The gametophyte is small (prothallus). Bryophytes have dominant gametophyte; pteridophytes onward have dominant sporophyte.
