Fig. 1. Illustration of tissues and lipid bodies in radicle meristem of maize embryo axes: (A) longitudinal section of radicle meristem (Bar = 80 µm, arrow indicates the sectioning location); (B) cross section of radicle meristem (Bar = 80 µm), numbers indicate locations from where micrographs were taken [root cap cells (1), outer (2), and inner (3) QC cells]; (C) Scanning electron micrograph where lipid bodies can be observed in three-dimension; (D) Contrasting visualization of one-dimension view of lipid bodies in TEM, sectioning in left cell occurred far from cell surface and sectioning in right cell occurred just below cell surface. Bar = 2 µm. Arrows point out lipid bodies. A and C photographs were courtesy of Dr. J.A. Hartwigsen.
