DO NOT mark the correct answer.
(7.12) Use the following diagram for questions 1-3 shown below.
1. This diagram is a plant cell rather than an animal cell because it contains…
A.
B.
C.
D.
2.
Organelles AB and E
Organelles A and D
Organelles B and AB
Organelles AB and D
Which organelle in both animal and plant cells functions to store nutrients, water, and wastes in a cell?
A.
B.
C.
D.
Organelle E
Organelle AC
Organelle A
Organelle D
3. This cell is Eukaryotic as shown by which organelle?
A.
B.
C.
D.
Organelle A
Organelle AB
Organelle BC
Organelle E
4. (7.12 D) In the school, the front office monitors and controls what enters and leaves the building by
controlling the doors and talking to each person who wants to come in or leave. In the cell, what
organelle performs the same service?
A. cell wall
B. cell membrane
C. nucleus
D. cytoplasm
5. (7.12 D) The picture provided is a cell organelle found in both plant and animal cells. Which of the
following is the purpose of this organelle?
A.
B.
C.
D.
It contains the DNA which controls the cell’s activities.
It produces proteins that are necessary for plant growth.
It stores the metabolic wastes from the plant.
It breaks down food to release energy for the cell and the organism.
6. (7.12D) A student is examining a cell through a microscope. She notes the following cell parts: cell
membrane, ribosomes, a central vacuole, a cell nucleus, and cytoplasm. The student states she is looking
at a plant cell. How does she know this is correct?
A.
B.
C.
D.
Only plant cells have cytoplasm.
Only plant cells have a vacuole.
She is not correct; she’s actually looking at an animal cell.
She can’t be sure because both plant and animal cells have those cell parts.
7. (7.12 E) What is the difference between the cell membrane and the cell wall?
A. The cell wall provides shape and structure for the cell whereas the cell membrane allows
substances in and out.
B. The cell membrane provides shape and structure for the cell whereas the cell wall allows
substances in and out.
C. The cell membrane and cell wall perform the same functions.
D. The cell membrane is only found in plant cells whereas the cell wall is found in both plant and
animal cells.
8. (7.12 E) Cells must be able to perform certain functions in order to survive. Which of the following must
all cells do to survive?
A. Obtain energy
B. Absorb wastes
C. Utilize oxygen
D. Continue growing
9.
(7.12 E) The organisms shown above live in water. What is the main function of the structures
identified by the arrows?
A.
B.
C.
D.
Absorbing water
Removing wastes
Movement
Getting food
10. (7.5A) What happens to the radiant energy absorbed by plants during photosynthesis?
A.
B.
C.
D.
It is recycled by plants and returned to the atmosphere.
It is converted into hydrogen and glucose.
It is stored as heat within the plant for cellular functions.
It is transformed into chemical energy.
11. (7.5A) Which of the following organisms can undergo photosynthesis?
A.
B.
C.
D.
I, II, and III
III
II and III
II

A. Chlorophyll produces chloroplasts.
B. Chemical energy is produced in the chloroplasts.
C. Photosynthesis occurs in the plant’s glucose.
D. Glucose is the green pigment in the chloroplasts.
13. (7.5A) Green plants produce their own food during photosynthesis. Which of these statements about
photosynthesis is true?
A. Water is one product of photosynthesis.
B. Oxygen is one product of photosynthesis.
C. Chlorophyll is one product of photosynthesis.
D. Carbon Dioxide is one product of photosynthesis.
14. (7.5A) Which of the following substances is not a product or reactant in the function of a chloroplast?
A. Protein
B. Oxygen
C. Glucose
D. Sunlight
15. (7.5A) Plants can provide the materials that animals use in cellular respiration, and animals can provide
some of the materials that plants use for photosynthesis. The image below shows the relationship
between photosynthesis and cellular respiration.
According to the diagram, how does cellular respiration aid the process of photosynthesis?
A. It produces ATP.
B. It makes glucose.
C. It produces mitochondria.
D. It produces carbon dioxide.
