D. guard cells
Terrestrial plants have stomata on the surface of their
leaves. A single stoma is surrounded by two guard cells
that change shape in response to environmental factors
and open or close the stoma. Which of the following best
explains how the structure of the leaf is used in
processes that occur in the plant?
A. Water enters the plant through the surface of the leaf
for transpiration.

C. Energy for cellular reproduction is absorbed through
the surface of the leaf.
D. Carbon dioxide enters the plant through the surface of
the leaf for cellular respiration.
As plants grow, stems and branches thicken or increase in
girth. This thickening is a result of cell division in the vascular
cambium. Vascular cambium can develop into either xylem or
phloem tissue within a plant. Because of this unique ability,
which of the following would NOT be a characteristic of
vascular cambium cells?
a. woody,
