1. Which process provides most of the oxygen found in the Earth’s atmosphere?
A. aerobic respiration
B. dehydration synthesis
C. fermentation
D. photosynthesis
2. The energy required for photosynthesis is provided by:
A. Sunlight
B. Proteins
C. Chlorophyll
D. Carbohydrates
3. During photosynthesis, trees convert carbon dioxide and other materials to:
A. Lipids
B. amino acids
C. nucleic acids
D. sugars
4. Which of these statements about photosynthesis and respiration is true?
A. Both processes produce food.
B. Both processes release energy from food.
C. Photosynthesis produces oxygen; respiration does not.
D. Photosynthesis produces carbon dioxide; respiration does not.
5. What is the purpose of vascular tissues?
A. They help to transport nutrients and waste throughout plants
B. They help to transport nutrients and waste throughout animals
C. They provide energy for plants
D. They provide energy for animals
6. A group of students separated 16 bean plants into four equal groups. They exposed each group to a different
number of hours of light. The table below shows the amount of light each group of bean plants received. All
other conditions were kept the same.
The students measured the total leaf surface area of each plant once a day
for two weeks.
Which of these processes were the students most likely studying?
A.
B.
C.
D.
diffusion
photosynthesis
chemosynthesis
mutation
7.
A group of students measured the volume of air they exhaled
during three different activities: sitting, walking, and running.
The volume of exhaled air is directly related to the amount of
carbon dioxide produced. The data the students collected are
summarized in the graph below.
Which of these processes produces carbon dioxide?
A.
B.
C.
D.
mitosis
diffusion
respiration
photosynthesis
8.
A.
B.
C.
D.
Which of the following pairs of materials is required for a cell to carry on respiration?
water and oxygen
glucose and oxygen
water and carbon dioxide
glucose and carbon dioxide
9. In a recent experiment, scientists studied the effects of increased carbon dioxide levels on the growth of pine
trees. The scientists observed that increased levels of carbon dioxide resulted in an increase in the average
circumference of the tree trunks. The change in circumference is a result of the process of
A.
B.
C.
D.
osmosis
adaptation
transpiration
photosynthesis
10. Use the information and the figure below to answer the following:
The diagram below shows a colony of prokaryotes and a single-celled eukaryote. The eukaryote contains
organelles that resemble the three types of bacteria found in the colony of prokaryotes. More than a billion
years ago, bacteria like these may have joined other prokaryotes to form colonies of cells. Researchers think
that these once free-living prokaryotes became the organelles of modern-day eukaryotes.
One of the organelles in the eukaryote releases energy from sugars. What is this process called?
A. respiration
B. transpiration
C. photosynthesis
D. chemosynthesis
