Produce sugar
Cells around the stomata that
react to stimulus are?
Parenchyma cells
Cheek cells
Sclerenchyma cells
Guard cells
The photograph to the right shows an
area of the root where cell division
takes place. Cells that are
undifferentiated and increase the
length of the root are found in the
A. epithelium
B. apical meristem
C. dermal tissue
D. ground tissue
The area marked A is home to epidermal
cells. Epidermal cells found on the top of a
leaf….
A. tend to be covered with thick, waxy layers

D. Tend to have thin, hair-like extensions
The areas marked C and D are home to
root hair cells. Root hair cells….

The flower of a plant usually
contains two types of specialized
cells, vegetative cells and germ
cells. Germ cells…
A. tend to contain pits in their cell walls
B. die when they are mature
C. produce gametes such as egg cells

The diagram below represents root epidermal
cells. The major function of the structures
labeled X is to
A. Increase the surface area for absorption of
water
B. Absorb complex food particles for transport
to the leaves

The underside of a leaf contains tiny pores
called stomata. These pores
lie next to specialized guard cells. The
structure of the specialized guard cells and
the stomata do not help the plant to….
A. release water during transpiration
B. capture pollen for sexual reproduction
C. absorb carbon dioxide for photosynthesis
D. enable the flow of nutrients from roots to the
rest of the plant
The leaves of a plant are dotted with
openings known as stomata. When open,
stomata allow the plant to exchange gases
and allow moisture to evaporate. This
helps draw water from the roots up into
the plant. These activities allow the plant
to…
A. maintain homeostasis
B. decompose organic matter
C. produce light energy
D. synthesize minerals
An acacia tree has many compound
green leaves. These leaves grow

minerals collected by….
A. The reproductive system
B. The root system
C. The excretory system
D. The nervous system
A buttercup produced a small, dry fruit. The
buttercup did not get enough water and died.
Its fruit fell on the ground and began to rot. A

Which of the Bermuda grass’s systems then sent
the nutrients from the buttercup fruit to its
leaves?
A. The integumentary system
B. The excretory system
C. The vascular system
D. The reproductive system
A horsetail opened stomata in its leaves to release
oxygen. The horsetail then took in carbon dioxide to
create energy. The horsetail used some of the energy
that it created to produce strobili, cone-like structures
that contain spores. When the horsetail used the
energy from its leaves to produce strobili, the vascular
system of the plant worked in conjunction primarily
with….
A. The excretory system
B. The reproductive system
C. The immune system
D. The root system

reason for this adaptation is…
