However, for those who do have food allergies, this distinction is very important. Food allergies can cause death. Food Allergens and Allergic Reactions. Like most allergic reactions, allergens in food are responsible for the food allergies. They are mostly proteins that resist the heat of cooking, stomach acids, and digestive enzymes.
In bryophytes (mosses and liverworts), the dominant generation is haploid, so that the gametophyte comprises what we think of as the main plant. The opposite is true for tracheophytes (vascular plants), in which the diploid generation is dominant and the sporophyte comprises the main plant. Bryophyte Generations
The gametophyte is haploid and produces haploid gametes by mitosis. The sporophyte of mosses consists of a seta and capsule whilst that of the ferns is more dominant and consists of fronds.They produce haploid spores by meiosis.pdate: sorry my question is unclear which generation produces spores and which produces gametes in MOSS and which generation produces spores and which produces gametes in FERNS.
