SEM showed reticulate surface pattern with regular to irregular polygonal, epidermal cell shape varies from
isodiametric, raised, straight; smooth anticlinal cell walls and flat to concave: macro-reticulate periclinal cell walls "Figure 3A and B".
hybrida, 8 to 19 layers of parenchymatic
isodiametric cells (Figure 2A, 2E, 21) were observed, while 9 to 16 layers were observed in U.
with a polygonal shape that range from
isodiametric to more or less elongated (Fig.
Median leaf cells
isodiametric, trigones various, not cordate 8 5.
the fundamental meristem cells are
isodiametric, larger in the medulla than in the cortical region of the cotyledon (Figure 4--ix).
The pollen grain of each specie was radially symmetrical,
isodiametric and isopolar.
Italian tractor firm Antonio Carraro specializes in small tractors for vineyard work, and the company's 7800 tractor features the "Actio" articulated chassis and
isodiametric steering.
Some callus cells are small and
isodiametric with a dense cytoplasm, these cells are more reactive to acetocarmine, staining a red color (GEORGE et al.
The intestine is
isodiametric, though some individuals have a slightly dilated secondary loop or rectum; however, this may be due to the presence of food in the gut, and the intestine never forms a sac-like structure.
Trichomes 2 [micro]m wide, cells typically
isodiametric, pale grey blue to blue green, slightly constricted at the cross walls (Fig.
communis, initially, three regions can be verified: the first is made up of hypodermic layer presenting from cuboids to cylindrical cells and two layers of
isodiametric cells inside this hypoderm, both presenting phenolic content, where volumous secretor idioblasts are immersed into; the second with a variable number of layers of
isodiametric cells, most of them with phenolic content; and the third, more internally located, with around three little layers of
isodiametric cells, vacuolated and with evident nucleus (Figures 2A and 2C).
Morphological and ultrastructural features of cells can be visualized by electron microscopy, which allows inferring characteristics of embryogenic cells, such as
isodiametric shape, small size, large nucleus, visibly evident nucleus, and organelles related to increased cell metabolism.
