  2. Anticline - Wikipedia

    en.wikipedia.org/wiki/Anticline

    Periclinal folds are a type of anticlines that have a well-defined, but curved hinge line and are doubly plunging and thus elongate domes. [5] Model of anticline. Oldest beds are in the center and youngest on the outside. The axial plane intersects the center angle of bend.

  3. Microsporangium - Wikipedia

    en.wikipedia.org/wiki/Microsporangium

    The archesporial cells divide by periclinal division to give a subepidermal primary parietal layer and a primary sporogenous layer. The cells of the primary parietal layer divide by successive periclinal and anticlinal divisions to form concentric layers of pollen sac wall. [citation needed]

    en.wikipedia.org/wiki/Unifacial_cambium

    Also in contrast to the bifacial cambium, the unifacial cambium is unable to expand its circumference with anticlinal cell division. Cell elongation provides a limited amount of expansion. Unifacial cambium plant morphology and life cycles

  5. Fold (geology) - Wikipedia

    en.wikipedia.org/wiki/Fold_(geology)

    Anticlinal traps are formed by folding of rock. For example, if a porous sandstone unit covered with low permeability shale is folded into an anticline, it may form a hydrocarbons trap, oil accumulating in the crest of the fold. Most anticlinal traps are produced as a result of sideways pressure, folding the layers of rock, but can also occur ...

    en.wikipedia.org/wiki/Anticlinal

    Anticlinal may refer to: Anticline, in structural geology, an anticline is a fold that is convex up and has its oldest beds at its core; Anticlinal, in stereochemistry, a torsion angle between 90° to 150°, and –90° to –150°; see Alkane_stereochemistry; Anticlinal division (botany)

[36] apiculate Having a short projection (an apicule) at one end; typically used to describe spore morphology. [37] apothecium Plural apothecia.

    A: antiperiplanar, anti or trans. B: synclinal or gauche. C: anticlinal or eclipsed. D: synperiplanar or cis. [2] Rotating their carbon–carbon bonds, the molecules ethane and propane have three local energy minima. They are structurally and energetically equivalent, and are called the staggered conformers.
