How does the cell wall serve as similar purpose in eukaryotic and prokaryotic cells?
It sorts and packages proteins for delivery.
It provides the cell with strength and rigidity.
It controls what can cross the cell membrane.
It aids in active transport.
A prokaryotic cell is similar to a eukaryotic cell in that both types of cells contain-
a mitochondrion
cytoplasm.
a nucleus.
vacuoles.
A Prokaryotic cell is unlike a eukaryotic cell in that-
a prokaryotic cell contains more space than a eukaryotic cell.
a prokaryotic cell contains a nucleus, and a eukaryotic cell does not contain a nucleus.
a prokaryotic cell contains a single membrane-bound organelle, and a eukaryotic cell contains multiple membrane-bound organelles.
a prokaryotic cell contains fewer genes than a eukaryotic cell.
Which feature of mobility can eukaryotic and prokaryotic cells have?
Flagella
Cilia
Pseudopoda
Pili
Maggie places cells of Elodea, a freshwater plant, on a wet-mount microscope slide. She uses a saltwater solution to prepare the slide. When she observes the cells under the microscope, what is she most likely to see?
The cells have shrunk within the cell walls.
The cell walls have dissolved, releasing the cell.
The cells will swollen, expanding the cell walls.
The cells have remained unchanged,
Felicia observed that the lettuce plants in her garden had wilted after several days of drought. The next day, there was a downpour of rain, and the leaves began to swell. What cellular processes caused this effect in the lettuce plants?
Photosynthesis
Active Transport
Cellular Transport
Osmosis
Which two processes does this diagram most directly model?
Energy Conversions and synthesis of new molecules.
Synthesis of new molecules and homeostasis.
Transport of molecules and energy conversions.
Homeostasis and transport of molecules.
Cells can generate as many as 38 molecules of ATP from one molecule of glucose. Which cellular processes is responsible for this production?
Protein Synthesis
Photosynthesis
Aerobic Respiration
Anaerobic Respiration
What conditions would cause a Euglena to fill with water?
The concentration of water is greater outside the cell than inside the cell.
The temperature of the water in the vacuole is higher than the temperature of its environment.
The concentration of the water inside the cell is the same as the concentration outside of the cell.
The temperature of the water in the vacuole is i lower than the temperature of its environment.
A virus must invade a host cell to -
grow.
protect itself.
replicate.
feed.
The virus that causes AIDS is damaging to the body because it -
prevents the normal transmission of nerve impulses.
target cells that fight invading microbes.
attacks specific red blood cells.
causes an abnormally high insulin level.
Which of the following factors was likely the greatest contributing factor to the 1916 influenza outbreak?
The virus was only able to gain access to new hosts because it lacked a membrane.
The virus was only able to enter the cells of certain hosts that carried flu receptors.
The virus passed easily between hosts because immunity to the flu had not been developed.
The virus was not airborne and was only spread by direct contact or fluid exchange.
Some viruses like the flu replicate via the lytic cycle by -
undergoing meiosis to create genetically diverse cells. Thes e cells are able to pass along the fittest traits from one generation to the next.
altering the genetic material of the host cell to make the host cell use its enzymes to assemble new viruses. These viruses then break out of the cell, resulting in cell death, and then spread the newly formed viruses to other cells.
regenerating through the process of mitosis, where each new cell contains a piece of genetic information from the provirus. The genetic material leaves the cell after a few weeks.
incorporating their genetic material into the host cell's genetic material. These viruses are called pro-viruses and remain dormant for several days, weeks, or years.
The Human Immunodeficiency Virus (HIV) causes a person to develop acquired immunodeficiency syndrome (AIDS). HIV remains active even after extensive treatment. Immunologists believe that HIV protects itself from attack by-
integrating with the chromosomes of the host cells.
fusing with the vacuoles of the host cells.
consuming the nuclei of host cells.
reproducing the mitochondria of host cells.
The Cell Cycle involves a stage called Interphase. During Interphase, a cell -
Shrinks.
divides into two.
rests and grows.
grows and develops a second set of DNA.
Which diagram represents a plant cell close to the final stage of mitosis?
F
M
T
C
A Plant cell will develop a cell plate during which phase of mitosis?
P
M
A
T
Image labeled P represents the stage of Prophase, which of the following best describes this stage?
Cell is splitting in half.
Duplicated chromosomes are separated.
Chromosomes align at the equator of the cell.
Chromosomes begin to condense and nuclear membrane breaks apart.
These changes in the form of the embryo are a direct result of -
antibodies and antigens inherited from the father.
differentiation and growth.
cellular transport and mutation.
uncontrolled cell division and mutations.
Unlike a eukaryotic cell, a prokaryotic cell lacks-
DNA and cytoplasm.
ribosomes and energy propelled flagella.
a cell wall and cell membrane.
a nucleus and membrane-bound organelles.
