dorsiventral การใช้

• It has simple leaves found dorsiventral in length.
• It has simple dorsiventral leaves with a dissected blade that are in length and wide.
• Simple nutation occurs in dorsiventral organs, such as flat leaves, both foliage and floral.
• Changes in temperature cause flowers to open or close by movements which resemble the simple nutation of dorsiventral organs.
• Molecular genetics has also shed light on the relation between radial symmetry ( characteristic of stems ) and dorsiventral symmetry ( typical for leaves ).
• The underside of the leaf-like lobes of foliose lichens is a different color from the top side ( dorsiventral ), often brown or black, sometimes white.
• Like movements of radial organs, such as stems, cylindrical leaves, and roots, have been termed circumnutation, or revolving nutation, to distinguish them from the simple nutation of dorsiventral organs.
• "' Leaf Anatomy "': The leaves of all species are built on a dorsiventral arrangement of cells, with the epidermis and palisade layer on the adaxial surface and the spongy tissue on the abaxial surface.
• When " Lellingeria " was first described in 1991, it was thought to always have a radially symmetrical rhizome, but it has since been learned that some of the species that belong in " Lellingeria " have a dorsiventral rhizome.
• "Klebsormidium ", the type of the Klebsormidiophyceae, is a simple filamentous form with circular, plate-like chloroplasts, reproducing by fragmentation, by dorsiventral, biciliate swarmers and, according to Wille, a twentieth-century algologist, by aplanospores.
• The others are " Hemidictyum " and " Asplenium " . " Hymenasplenium " was segregated because it is a natural grouping with differing rhizome morphology  dorsiventral v . radial for the rest of Asplenium, differing chromosome count  x = 39 v . x = 36 for the rest of Asplenium, and a clear monophyletic grouping based on genetic analysis.
• It is a medium-sized plant, growing to about 4 5 feet ( though 10 12 feet in a sheltered place at Arduaine Garden in Argyll, Scotland ) and even though the rhizome does not grow a trunk, it is clearly related to the other tree ferns due to features that were apparently already present in their common ancestor, like " " pneumathodes " ", and the rhizome which changed from the dorsiventral symmetry typical of the other ferns, to a radial symmetry typical of tree ferns.
