AP BIOLOGY

Detailed explanation-1: -In bryophytes, such as mosses and liverworts, the gametophyte is the dominant life phase, whereas in angiosperms and gymnosperms the sporophyte is dominant. The haploid phase is also dominant among fungi.

Detailed explanation-2: -Gametophyte is a dominant phase in the life cycle of a bryophyte.

Detailed explanation-3: -The gametophyte is the dominant life phase in the Bryophytes. The gametophyte produces structures known as antheridia and archegonia, which produce the male and female gametes respectively.

Detailed explanation-4: -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-5: -The gametes are produced on the gametophytes. The sperm are produced within tiny, typically stalked, club-shaped structures called antheridia and you can also see bryophyte sperm referred to as antherozoids. The stalk anchors the antheridium to the gametophyte. Each antheridium produces numerous sperm.
