new sprouts. These sprouts are an
example of
A. Asexual reproduction with tubers.
B. Asexual reproduction with runners.
C. Sexual reproduction with stem cuttings.

The vast majority of plants function best when
there is ample water and temperatures are
well above freezing throughout the year.
Plants, unlike animals, do not have the luxury
of body insulation or locomotion.
Consequently, as the temperatures decrease in
the winter many plants respond by losing
leaves and slowing growth.
The statement above best summarizes which
plant response to the environment?
A. Dormancy
C. Fertilization
B. Phototropism
D. Hydrotropism
The model below represent which plant
process?
A. Fertilization
B. Respiration
C. Transpiration
D.Photosynthesis
Which of the following is a product of
photosynthesis?
A. Carbon Dioxide
B. Chlorophyll
C. Nitrogen
D.Oxygen

important to the plants survival? Use
reasoning to defend your answer.
 Transpiration
 Fertilization
 Photosynthesis
 Respiration

Your neighbor had to go out of town for three weeks. You
agreed to water her plants every few days. She closed the
curtains so people could not see into the house. The only
window that was NOT covered was in the kitchen. After two
weeks, you noticed that the only healthy plant was in the
kitchen. What question could you ask yourself to find out why
the other plants do not look healthy anymore?
A. Does the amount of sunlight a plant receives affect how well
the plant grows?
B. Should I repot the plants into bigger pots to give them more
room to grow?
C. Should I water the plants with something other than water?
D. Do I need to water the plants more often to make them grow
better?
