Visual Vocabulary
Below are vocabulary words and definitions. Your task is to draw a picture to demonstrate
the definition.
physiology
The scientific study
of an organism’s vital
functions, including
growth and
development.
phototropism
geotropism
external
features
function
Movement or growth
in response to lights
or colors of lights.
A plant whose roots
grow down into the
soil as a response to
gravity.
The outward
appearance of a
distinct part that can
be seen, such as the
roots, stem, leaf or
flower of a plant.
The physiological
activity of a part (the
specific role a part
has in the system)

Plants have different signals for attracting pollinators. It is not uncommon for
the same plant to have more than one signal. Which of the following would NOT
be a way in which plants attract pollinators?
16
17
A
presence of barbs
B
specific texture or pattern
C
strong scents
D
bright colors
Plant species rely on various
methods of seed dispersal.
Which type of seed dispersal
would most likely be used by the
organism shown in the diagram?
F
animal dispersal
G
wind dispersal
H water dispersal
J
gravity dispersal
18
Trees that grow in a forest tend
to grow very tall, with few
branches. The same species of
tree grown in an open area
tends to grow shorter and wider,
with many branches. The
stimulus responsible for theses
different growth patterns is the
amount of A
wind striking the tree
B
light reaching the tree
C
nutrients in the soil
D
water in the ground

The maypop flower is a long vine that grows along fences. These plants have
tendrils that allow them to grab and hold onto the fences. How does this
adaptation help the plant?
F
wrapping around a nearby object for support
G
producing reproductive structures later in the
growing season
H
attracting insects which serve as pollinators
J
encouraging water and mineral transport to other
parts of the plant
Complex animals use their
circulatory systems to provide
their cells with water and food.
Plants do not have circulatory
systems. What have they
developed to move nutrients and
water.
A
xylem
B
cork cells
C
chloroplasts
D flowers

An acorn is a seed. Its shape is
very different from the shape of
a dandelion seed. Which of the
following BEST describes the
advantage of the shape of the
acorn?
F
The acorn is more likely to
stick to animal fur.
G
The acorn is less likely to
attract hungry animals.
H The acorn can be blown to a
better growing location.
J
The acorn stores more
materials to help it start
growing.

A spiny cactus is growing very
successfully in an Arizona
dessert. This plant has many
adaptations to its native
environment that make it
successful in harsh conditions.
Three adaptations that the spiny
cactus has are A
broad leaves, deep roots,
sharp spines
B
waxy leaves, sharp spines to
preserve moisture, a shallow
root system
C
sharp spines, small bad
tasting leaves, deep roots
D
large, shallow root system,
sharp spines, thick trunk
23
Some species of flowers have
markings that are visible only to
insects with the ability to see
ultraviolet light. These markings
help the plant F
avoid parasitic insects
G
attract pollen gathering
insects
H
seek out moisture in the soil
J
create a strong scent to
attract bats
