AP BIOLOGY

Detailed explanation-1: -In a bryophyte, all the vegetative organs belong to the gametophyte, which is the dominant and most familiar form; the sporophyte appears for only a short period. The sporophyte is dependent on the gametophyte and remains permanently attached to it in order to gain nutrition and protection.

Detailed explanation-2: -The sporophyte generation is dependent on the photosynthetic gametophyte for nutrition. Cells within the sporangium of the sporophyte undergo meiosis to produce male and female spores, respectively.

Detailed explanation-3: -In bryophytes, sporophyte is dependent on gametophyte.

Detailed explanation-4: -In Bryophytes, sporophyte is attached to the gametophyte. Gametophyte is photosynthetic, and hence, sporophyte gets its nourishment from the gametophyte.
