Question

The dominant photosynthetic phase in the life cycle of pteridophyta is equivalent to the

• A. Gametophytic phase of bryophyta
• B. Sporophytic phase of bryophyta
• C. Gametophytic phase of pteridophytes
• D. Gametophytic phase of gymnosperm

Answer 1

The correct option is A Gametophytic phase of bryophyta

The correct answer is gametophytic phse of bryophytes.

Bryophytes and Pteridophytes show an intermediate condition called the haplo-diplontic life cycle, where phases are multicellular. But the dominant phase differs. In Bryophytes, the dominant phase is the gametophyte and in Pteridophytes, it is the sporophyte.
