Q.Which of the plant group has gametophyte as a dominant phase?

Step 1. Recall what 'gametophyte-dominant' means: the haploid (n) phase is the conspicuous, long-lived, independent plant body, while the diploid (2n) sporophyte is reduced.

Step 2. Check each option against this test. In Pteridophytes the sporophyte (2n) is dominant and independent, with the gametophyte reduced to a small prothallus — so (a) is wrong. In Gymnosperms and Angiosperms the sporophyte is overwhelmingly dominant and the gametophyte is cut down to just a few cells — so (c) and (d) are wrong.

Step 3. In Bryophytes, by contrast, the plant body itself IS the gametophyte; the sporophyte stays attached to and dependent on it, differentiated into only a foot, seta and capsule.

Match each option's dominant life-cycle phase against the definition of gametophyte-dominance.

• Confusing 'gametophyte present' with 'gametophyte dominant' — pteridophytes, gymnosperms and angiosperms all HAVE a gametophyte, but it is reduced, not dominant.
• Assuming bigger/more visible groups (like angiosperms) must have the dominant gametophyte, when in fact their gametophyte is microscopic.
