Which of the following statements accurately describes the arrangement of vascular bundles in typical eudicot and monocot stems, as shown in Figure 35.17?
A: In eudicot stems, vascular bundles are scattered throughout the ground tissue, while in monocot stems, they form a ring.
B: In eudicot stems, vascular bundles form a ring with xylem facing the cortex, and phloem facing the pith.
C: Monocot stems typically have vascular bundles arranged in a ring, and their ground tissue is partitioned into pith and cortex.
D: Eudicot stems have vascular bundles arranged in a ring with xylem facing the pith and phloem facing the cortex, whereas monocot stems have scattered vascular bundles.
Explanation
Figure 35.17a and the accompanying text state that eudicot stems have vascular bundles arranged in a ring, with xylem facing the pith and phloem facing the cortex. Figure 35.17b and its text explain that monocot stems have scattered vascular bundles and their ground tissue is not partitioned into pith and cortex.
