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.
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]
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
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 ...
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)
anticlinal Pointing up, away from, or perpendicular to a surface. Contrast periclinal. antrorse Directed forward or upward, e.g. of hairs on a stem. Contrast retrorse. apetalous Lacking petal s. apex. pl. apices. The tip; the point furthest from the point of attachment. aphananthous (of flowers) Inconspicuous or unshowy, as opposed to ...
anticlinal Perpendicular to a surface; [35] used to refer to hyphal alignment. apical Located at the highest point (the apex), the tip, or the end of something. [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.
