Anatomy of the root, an apomorphy of the vascular plants. A. Root whole mount. B. Root longitudinal-section. C. Whole root cross-section. D. Close-up of central vascular cylinder, showing tissues. Roots are characterized by several anatomical features. First, the apical meristem is covered ...
There are eight structures found on the outside of a stem: 1. Terminal bud – contains apical meristem; found at the tip of a stem; it increases the length of a stem Review apical meristem with your students. They should remember its general function when you talked about roots. 2. Node...
This paper is organized as follows: Section “Stem modeling” briefly describes the plant stem anatomy and the role of each stem layer, it also shows the impedance model circuit’s analysis and their representation. Section “Problem definition” illustrates the problem formulation. Section “Experime...
cross-section areas compared to the control group. This reduction had a significant impact on the size of the leaflets, as indicated in Table1. The diminution of the size ofD. odoriferaleaflets, which also affects the leaflet thickness, can be explained by the overall reduction in spongy and ...
Most ferns have rhizomes with no vertical stem. The exception is tree ferns, with vertical stems up to about 20 meters. The stem anatomy of ferns is more complicated than that of dicots because fern stems often have one or more leaf gaps in cross section. A leaf gap is where the vascula...
Figure 4 exhibits the processing steps for Mussatia hyacinthine stem cross-section, traditionally prepared sample. The machine learning WEKA segmentation method was used to process the image. The method was largely unchanged from the description in the WEKA section of this paper. Minor adjustments we...
d Cell morphology of leaf vein cross section in wild-type and transgenic plants. e–k Comparison of cell morphology in different tissues. ZGDD: control soybean Zigongdongdou (transgenic receptor). FU160 is the typical transgenic line overexpressing GmFULa. The data represent mean ± SE ...
Stem Anatomy Figure 2. The stem of common St John’s Wort (Hypericum perforatum) is shown in cross section in this light micrograph. The central pith (greenish-blue, in the center) and peripheral cortex (narrow zone 3–5 cells thick just inside the epidermis) are composed of parenchyma ...

and its close correlation to stem dry matter content (StDMC, the ratio of stem dry mass to stem water-saturated fresh mass). StDMC is a good proxy of SSD in herbaceous plants with a ratio of approximately 1:1199, despite substantial differences in stem anatomy among botanical families236, ...
