Helpful Hint
The table below provides some information concerning organelles and organs.
7) Based on this information, which statement accurately compares organelles to organs?
A
Organelles carry out functions similar to those of organs.
B
Functions are carried out more efficiently by organs than by organelles.
C
Organs maintain homeostasis while organelles do not.
D
Organelles function in multicellular organisms while organs function in single-celled organisms.
Helpful Hint
Some human body cells are shown in the diagrams below.
8) These groups of cells represent different

systems that are responsible for a specific life activity
B
organs that help to carry out a specific life activity
C
tissues in which similar cells function together
D
organelles that carry out different functions
9) Homeostasis in unicellular organisms depends on the proper functioning of
A
organelles
B
insulin
C
guard cells
D
antibodies
10) Which of the following organelles is correctly paired with its specific function?
A
chloroplast - transport of materials
B
vacuole - production of ATP
C
ribosome - synthesis of proteins
D
cell membrane - storage of hereditary information
11) Which sequence of terms represents a decrease from the greatest number of structures to the least number of structures present in a cell?
A
nucleus → gene → chromosome
B
gene → chromosome → nucleus
C
gene → nucleus → chromosome
D
chromosome → gene → nucleus
12) Most of the hereditary information that determines the traits of an organism is located in
A
the numerous ribosomes in certain cells
B
the nuclei of body cells of an individual
C
only those cells of an individual produced by meiosis
D
certain genes in the vacuoles of body cells
13) As a human red blood cell matures, it loses its nucleus. As a result of this loss, a mature red blood cell lacks the ability to
A
carry out cell division
B
release hormones to the blood
C
take in material from the blood
D
pass through artery walls

4
C
3
D
2
15) An organelle that releases energy for metabolic activity in a nerve cell is the
A
chloroplast
B
ribosome
C
vacuole
D
mitochondrion
16) Muscle cells in athletes often have more mitochondria than muscle cells in nonathletes. Based on this observation, it can be inferred that the muscle cells in athletes
A
have a smaller demand for cell proteins than the muscle cells of nonathletes
B
have a greater demand for energy than the muscle cells of nonathletes
C
have nuclei containing more DNA than nuclei in the muscle cells of nonathletes
D
reproduce less frequently than the muscle cells of nonathletes
17) Certain poisons are toxic to organisms because they interfere with the function of enzymes in mitochondria. This results directly in the inability of the cell to
A
store information
B
release energy from nutrients
C
build proteins
D
dispose of metabolic wastes
18) Plants in areas with short growing seasons often have more chloroplasts in their cells than plants in areas with longer growing seasons. Compared to plants in areas with longer growing seasons, plants in areas with shorter growing seasons most likely
A
make and store food more quickly
B
grow taller
C
have a higher rate of protein metabolism
D
have a different method of respiration
Helpful Hint
The diagram below represents two cells, X and Y.
19) Which statement is correct concerning the structure labeled A?
A
It is involved in cell communication in cell X, but not in cell Y
B
It prevents the absorption of CO2 in cell X and O2 in cell Y.
C
It represents the cell wall in cell X and the cell membrane in cell Y.
D
It aids in the removal of metabolic wastes in both cell X and cell Y.
Helpful Hint
The diagrams below represent two different cells and some of their parts. The diagrams are not drawn to scale.
