What does xylem carry up the stem?
Water & Glucose
Glucose
Water
Vitamins
What does phloem carry down the stem?
Water
Sugar
Oxygen
All of the above
An important function of the stem of the plant is
supporting the plant
providing a source of energy
site of photosynthesis
absorbs nutrients and water
The leaves of plants -
do not vary in size and shape
anchor the plant to the ground
shade the plant from the sun
make food for the plant
Roots perform all of the following functions EXCEPT
Absorbing nutrients from the soil
Anchoring the plant in the soil
Absorbing water from the soil
Carrying out photosynthesis
What part of the plant is #3?
flower
root
leaf
stem
The part of the plant that originally grows out of the ground is called -
roots
shoots
stem
leaves
Which of the structures below is NOT an external structure?
leaves
stem
roots
xylem
Which of the structures below are internal structures of a plant?
roots
leaves
xylem & phloem
shoots
Which diagram represents the correct growth of the plant under the influence of the external force of gravity?
A
B
C
D
Cactus are adapted to live in arid (dry) environments such as the desert. Deserts are an ecosystem that are always in a state of drought (low rainfall). Which adaptation do cactus have that allow them to survive in a drought?
small vacuoles to store small amounts of water
more xylem and phloem to transport more water
vascular tissue that contains plant cells with large vacuoles to store more water
long spines (thorns) to absorb water when it rains
The energy transformation that occurs with photosynthesis is-
radiant energy into mechanical energy
radiant energy into stored chemical energy called glucose
stored chemical energy into glucose
mechanical energy into stored chemical energy
When you plant a seed, gravity is an external force the seed must overcome in order to sprout. Which direction do the roots and shoots grow under the influence of geotropism?
The roots will grow downward with the force of gravity and the shoots will grow up out of the ground away from gravity.
The shoots will grow downward with the force of gravity and the roots will grow up out of the ground away from gravity.
The roots will grow downward with the force of gravity and the shoots will grow up out of the ground toward sunlight.
The roots will grow sideways way from the force of gravity and the shoots will grow up out of the ground avoiding the sunlight.
From left to right, this series of plant diagrams represents -
The vacuoles of plant cells with high turgor pressure.
The loss of water in the vacuoles of the plant cells, decreasing the turgor pressure needed to keep the plant rigid.
The gaining of water in the vacuoles of plant cells, increasing the turgor pressure needed to keep the plant rigid.
The cell membranes of all the plant cells breaking and leaking water to lose turgor pressure.

Plants are considered producers which means-
they consume their own food
the convert their own food
they transform their own food
they create their own food
Which cell represents a non-woody plant (not a tree) that has low turgor pressure?
a
b
neither
both
Which external stimuli is influencing Groot's growth?
geotropism
hydrotropism
thigmotropism
phototropism
Non-woody plants (not trees) can wilt. Wilting is a result of -
the vacuole losing water pressure, decreasing turgor pressure
the vacuole increasing water pressure, increasing turgor pressure
the cell membrane leaking water, decreasing turgor pressure
an increase in the mass of cytoplasm, increasing turgor pressure
Which force / stimuli listed is NOT external?
gravity
water
light
water pressure
Which force / stimuli listed is internal?
gravity
water
light
water pressure
The shape of plants leaves are-
inherited from the parent plant by the genes in the cytoplasm
inherited from the parent plant by the genes in the nucleus
inherited from the parent plant by the genes in the chloroplast
inherited from the parent plant by the genes in the vacuole
Emergent Seedlings need to overcome forces to grow. Which force listed is internal that seeds need in order to sprout out of the ground?
Gravity
Light
Water availability
Turgor Pressure
Which plant cell structure provides the function to keep the cell rigid, providing support for the plant?
cell membrane
cell wall
chloroplast
vacuole
