Fig. 1From: Parametric mapping of cellular morphology in plant tissue sections by gray level granulometryCellular morphology of a whole tissue slice. a Sample image of a cross section of a maize internode showing the variability in cell morphology. b Focus on a smaller region close to the epidermis. Parenchyma tissue is composed of large polygonal cells, whereas rind tissue is composed of small cells with thick cell wallBack to article page
