Textbook Question
Chapter 35, Problem 3A
If you were to relocate the pericycle of a plant root to the epidermal layer, how would it affect root growth?
a. Secondary growth in the mature region of the root would not occur.
b. The root apical meristem would produce vascular tissue in place of dermal tissue.
c. Nothing would change because the pericycle is normally located near the epidermal layer of the root.
d. Lateral roots would grow from the outer region of the root and fail to connect with the vascular tissue.
