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.
Diagram of antheridium anatomy. An antheridium or antherida (plural: antheridia) is a haploid structure or organ producing and containing male gametes (called antherozoids or sperm). It is present in the gametophyte phase of cryptogams like bryophytes and ferns, and also in the primitive vascular psilotophytes.n bryophytes, the antheridium is borne on an antheridiophore, a stalk-like structure that carries the antheridium at its apex. In many gymnosperms and all angiosperms, the male gametophytes have been reduced to pollen grains and their antheridia have been reduced to a single generative cell within the pollen grain.
