Document Summary

Central section, which is the vascular cylinder: vascular tissue system. Both of them have an epidermis on the outside. Ground tissue system mostly made of cells forming a cortex. One layer on the inside of the cortex before we get to vascular cylinder known as the endodermis. Vascular cylinder is also called a stele: whether monocot or dicot, it is right in the center. In the monocot, there is a section on the inside known as the pith. Xylem and phloem are right in the center of the root. In a monocot, there are these cells that are not the xylem or the phloem. See the xylem more easily because it tends to have bigger cells. Xylem tends to be more toward the center; phloem tends to be more toward outside. Endodermis tends to one layer of cells thick: important for roots.
