Anticlinal or periclinal cell walls with more thickening are often found in species from regions subjected to water deficit (Solereder, 1908; Metcalfe and Chalk, 1979) and are related to the reduction of water loss by transpiration, decreasing heating within plant organs, maintaining its architecture, and reflecting higher luminosity (Dickison, 2000; Leite and Scatena, 2001).
En tanto que las paredes periclinales o radiales son delgadas, y se conectan internamente con el borde espiral o ribbon que se origina a partir de las paredes anticlinales internas de esta misma estructura (Fig.
SEM showed reticulate surface pattern with irregular polygonal mostly hexagonal, epidermal cell shape varies from isodiametric, raised, straight; smooth anticlinal cell walls and flat to slightly concave periclinal cell walls "Figure 3C and D".
Structural aspects of the epidermis, such as the outline of the anticlinal wall and the shape of the external periclinal wall of the epidermal cells may be related to light intensity.
The integuments started with periclinal and oblique divisions at the base of the nucellus.
Convex cells morphology of microstructured surface which is found on the leaves and stems of flowering plants is originated by expansion of the outer side (periclinal wall) of the epidermis cells [35, 36].
Many [F.sub.2] folds have periclinal fold axes that split or die out along the hinge line and are doubly plunging, which most likely causes the variable plunge of [F.sub.2] fold axes (Fig.
Sections of leaves from plants cultivated in the greenhouse showed the layer of palisade cells well-organized and some of these cells underwent periclinal division; well-developed cuticle; presence of idioblasts containing crystals (Figure 3).
