Explicació
In a dicot stem, the region between the endodermis and the vascular bundles is called the pericycle.
-
Endodermis:This is the innermost layer of the cortex, a single layer of cells that separates the cortex from the vascular bundles.
-
Pericycle:This is a layer of cells located just inside the endodermis and is the outermost part of the stele (vascular cylinder).
-
Vascular bundles:These are made up of xylem and phloem, which are arranged in a ring in dicot stems.
