Sport (botany) Sport (botany) In botany, a sport or bud sport, traditionally called lusus, is a part of a plant that shows morphological differences from the rest of the plant. Sports may differ by foliage shape or color, flowers, or branch structure. Sports with desirable characteristics are often propagated vegetatively to form new cultivars that retain the characteristics of the new morphology. Such selections are often prone to "reversion", meaning that part or all of the plant reverts to its original form. An example of a bud sport is the nectarine, at least some of which developed as a bud sport from
Discodermia calyx Discodermia calyx Discodermia calyx are bowl-shaped sponges that are found in shallow waters in central and southern Japan. These sponges are distributed by the central Kuroshio current and are therefore localized along this current. Like many other sponges, "D. calyx" are very porous. They use the pores in their outer walls to draw in water which they then expel, retaining the nutrients dissolved in the water to nourish themselves. To keep water flowing in and out, the flagella that line their pours beat in either direction. The sponge is most known and used for a molecule that can be extracted
