When grass is cut with a lawn mower, it gives off a
distinct aroma. Why does newly-mowed grass smell a
little bit sweet?
A. Sugars are produced when the cut leaves of grass
begin to decay in sunlight.
B. Sugars stored in the roots are sent to repair the
damage to the grass leaves.
C. When the grass leaves are damaged, some of the
sugar produced in the leaves escapes.
D. When grass leaves are cut, a small amount of sugar is
produced at the site of injury to plug the phloem.

ATP/Photosynthesis/Cellular Resp.
 What the heck is that?
In plants, water can escape through the
leaves by the process of transpiration. Which
of the following structures are involved in
transpiration?
A. xylem, phloem, stomata
B. root hairs, xylem, stomata
C. phloem, root hairs, xylem
D. stomata, phloem, root hairs
FUN FACT: Only
1% of the suns
energy is absorbed
by plants, the rest is
reflected back to
space or
transformed into
heat in the
atmosphere

 3 short answer, 4 multiple choice
 1) Describe the difference between xylem and phloem.
 2) Describe the process of transpiration.
 3) Explain the purpose and function of flowers for a
plant. Would the plant survive without petals?
Explain.
Multiple choice
4)What is the main function of leaves?
 A. Leaves provide support for growth and a place
to store food.
 B. Leaves provide a place for photosynthesis to
occur.
 C. Leaves absorb water and minerals and
transport nutrients to the stem.
 D. Leaves create a barrier that prevents water in
the plant's tissues from evaporating.
5) Terrestrial plants have stomata on the surface of their
leaves. A single stomata 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 plants?
 A. Water enters the plant through the surface of the
leaf for transpiration
 B. Gases for photosynthesis are exchanged through
the surface of the leaf.
 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 reproduction.
6) The diagram below represents a flower, the reproductive structure of
some plants. Most flowers have both male and female structures for
fertilization and reproduction
Which structure is represented by the letter A in the diagram above?
A. the stamen, a male structure which produces pollen
B. the pistol, a female structure which collects pollen and passes it to the
ovary
C. the sepal, a modified leaf used for protection of the flower
D. the petals, decorative structures which attract pollinators
7) A unique characteristic of the banyan tree is that roots
grow down from its branches into the ground. The tree can
appear to have several trunks. What advantage does this
root characteristics give the banyan tree over other trees?
A. The roots provide shelter for ground dwelling animals,
which carry nutrients to the tree
B. It can grow near the equator, because aboveground roots
are more protected from the sun
C. It can only grow in humid climates because aboveground
roots are more likely to dry out and die during droughts
D. It can grow in areas prone to hurricanes and typhoons,
because the roots make the tree more stable in high
winds

Vascular plant tissue that carries sugars.
2) Transpiration is the process of water movement through
a plant and its evaporation from leaves.
3) The purpose of the flower is for plant reproduction. The
plant can survive without petals on the flower because it is
not directly involved in the reproduction of the plant.
