Question 1 Report

Which of the following is true of the transverse section of a dicot system?
Answer Details
The correct option is "the xylem is more interiorly located than the phloem." In a dicot stem, the vascular bundles are arranged in a ring-like structure, with the xylem located towards the center and the phloem towards the periphery. This arrangement is called a "closed" vascular system, in contrast to the "open" vascular system of monocots. The cambium, a layer of meristematic cells that gives rise to new xylem and phloem, lies between the xylem and phloem in the vascular bundles. The cortex is the outermost layer of the stem, while the epidermis is the outermost layer of cells that covers the stem.
