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 way in which the alternation of generations occurs in plants depends on the type of plant. 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.ryophytes are nonvascularized plants that are still dependent on a moist environment for survival (see Plant Classification, Bryophytes. Like all plants, the bryophyte life cycle goes through both haploid (gametophyte) and diploid (sporophyte) stages.
