geotropic การใช้

• Geotropic reaction is regulated by light ( more exactly by phytochrome action ).
• Thus twining plants exhibit both true nutation and nutation due to geotropic sensitiveness.
• Coleoptiles also exhibit strong geotropic reaction, always growing upward and correcting direction after reorientation.
• This leads to the secretion of geotropic, and altered ( wrinkled ) leaf morphology, if leaves are present.
• The white visible part is the root, or radicle which you can see is trying to go downwards as it is positively geotropic.
• The individual flowers are white to yellowish-white in color and are negatively geotropic ( that is, growing upwards and away from the ground ).
• "' Secotioid "'fungi are an intermediate growth form between mushroom-like hymenomycetes and closed bag-shaped geotropic orientation of the hymenophore needed to allow the spores to be dispersed by wind, and the basidiospores are not forcibly discharged or otherwise prevented from being dispersed ( e . g . gills completely inclosed and never exposed as in the secotioid form of " Lentinus tigrinus " )  note some mycologists do not consider a species to be secotioid unless it has lost ballistospory.
