Cross Section Of Dicot Stem

Vascular bundles are arranged in a circle.

Cross section of dicot stem. An herbaceous dicot stem is very similar to the apical end of a woody dicot stem where no secondary growth has taken place figure 32 2b. Monocot and dicot stems. The arrangement of tissues is the same.

The other important regions of the dicot stem are cortex medullary rays pericycle and pith. Note that young herbaceous stems may have stomates for gas exchange though the leaf is the main site of gas exchange with many morestomates than the stem. A cross section of a dicot stem would reveal.

The vascular system in dicots comprises of the two distinct regions cortex and stele which are absent in the monocot stems. This video provides a demonstration of making thin cross sections by hand for plant material such as stems and roots. Figure 32 11 shows a cross section of an herbaceous dicot stem.

A cross section of a generalized herbaceous dicot stem appears on the left. In dicot stem the epidermis is the outermost layer along with the multicellular epidermal stem hairs. An epidermis to the outside covered by a cuticle a waxy layer that reduces water loss from the surface.
