If it takes more than a week, continue doing it nightly until the gagging stops. Move your gag reflex trigger back further by extending the area that you brush. Brush 1/4 to 1/2 inch further back on your tongue. This new area is now your gag reflex trigger and where you should do your nightly brushing. Work on that area nightly until you can brush that part of your tongue without gagging.
Flowering Plants. The Division name Anthophyta simply means flowering plant; the other term, angiosperm, refers to the seeds being borne in a vessel called a fruit. The plant that you see is the diploid sporophyte.
A gametophyte is the haploid multicellular stage in the alternation of generations life cycle of plants and algae. It develops from a spore by mitotic cell division. Spores are the products of meiosis in sporophytes. Gametophytes produce haploid gametes by mitosis. In some types of plants and algae (e.g. Ulva) gametes are isogamous --that is, the gametes are all of one size, shape and general morphology.
