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.
In flowering plants, the megagametophyte (also referred to as the embryo sac) is much smaller and typically consists of only seven cells and eight nuclei. This type of megagametophyte develops from the megaspore through three rounds of mitotic divisions.t consists of three parts: The integument(s) forming its outer layer(s), the nucellus (or remnant of the megasporangium), and female gametophyte (formed from haploid megaspore) in its center. The female gametophyteâspecifically termed a megagametophyte âis also called the embryo sac in angiosperms.
