Which organelle is present in the cells of a mouse but NOT present in the cells of a bean plant?
cell wall
chloroplast
cell membrane
centriole
Which statement best describes these cells?
Cell B lacks vacuoles while cell A has them.
DNA would not be found in wither cell A or cell B
Both cell A and cell B use energy released from ATP
Both cell A and cell B produce antibiotics
What is the main function of a vacuole in a cell?
storage
coordination
synthesis of molecules
release fo energy
The process of osmosis is best illustrated by the movement of
water into root hair cells
oxygen into red blood cells
carbon dioxide through stomates
glucose through phloem
While viewing a slide of rapidly moving sperm cells, a student concludes that these cells require a large amount of energy to maintain their activity. The organelles that most directly provide this energy are known as
vacuoles
chloroplasts
mitochondria
ribosomes
Which row in the chart below above explains the movement of molecules in the process of active transport?
Row (1)
Row (2)
Row (3)
Row (4)
Which row in the chart above best explains the movement of molecules in the process of passive transport?
Row (1)
Row (2)
Row (3)
Row (4)
Which letter indicates a cell structure that directly controls the movement of molecules into and out of the cell?
A
B
C
D
The chart above shows examples from two groups of organisms, multicellular and unicellular. The tissues and organs in group A perform functions that are
similar to those performed by the tissues and organs in group B
similar to those performed by the cell organelles in group B
different from those performed by the tissues and organs in group B
identical to those performed by the cell organelles in group B
An ameba, a one-celled organism, can move, ingest, and transport materials within the cell, because it has
organs
organelles
tissues
systems
Which statement concerning production of offspring is correct?
Production of offspring is necessary for a species to survive, but it is not necessary for an individual to survive.
An organism can reproduce without performing any of the other life processes.
Production of offspring is necessary for an individual organism to survive, while the other life processes are important for a
species to survive.
Reproduction is a process that requires gametes in all species.
While viewing a specimen under high power of a compound light microscope, a student noticed that the specimen was
out of focus. Which part of the microscope should the student turn to obtain a clearer image under high power?
eyepiece
coarse adjustment
fine adjustment
nosepiece
Cell membranes are said to be selectively permeable. Which statement best explains what selectively permeable
means?
The cell membrane lets certain substances enter the cell and keeps certain substances out of the cell.
The cell membrane allows only large molecules to diffuse into the cell.
The cell membrane has pores that let only water and glucose into the cell and carbon dioxide out.
The cell membrane prevents any harmful substance from entering the cell.
The cell represented above produces oxygen.
Which structure allows the passage of this oxygen to the environment?
A
B
C
D
The diagram above represents a cell in water. Formulas of molecules that can move freely across the cell membrane
are shown. Some molecules are located inside the cell and others are in the water outside the cell.
Based on the distribution of these molecules, what would most likely happen after a period of time?
The concentration of O2 will increase inside the cell.
The concentration of CO2 will remain the same inside the cell.
The concentration of O2 will remain the same outside the cell.
The concentration of CO2 will decrease outside the cell.
