Which of the Following Would Not Be Seen in a Cross-Section

Question

Which of the following would not be seen in a cross-section through the woody part of a root?
A) sclerenchyma cells
B) parenchyma cells
C) sieve-tube elements
D) root hairs
E) vessel elements

Accepted Answer

Root hairs are found in the epidermis of roots, primarily in the region of maturation near the root tip, not in the woody part of a root. The other options (sclerenchyma cells, parenchyma cells, sieve-tube elements, and vessel elements) are all components that can be found within the woody (vascular) tissues of roots.
