Unit 2 Test Review
Which distinguishes anaerobic respiration from aerobic respiration?
Anaerobic respiration produces little ATP, while aerobic respiration produces large quantities of ATP.
Why do leaf cells contain many chloroplasts?
Cells located in a leaf need more sunlight for photosynthesis.
Which best explains the importance of a selectively permeable cell membrane?
It controls what is allowed to enter or leave the cell.
An animal cell is placed into distilled water. Which best describes what will happen to the animal cell? (distilled=purified)
It will increase in size until it ruptures.
How does the amount of cellular energy used to move a molecule into a cell by active transport compare to the energy used for its movement by passive diffusion?
More energy is used
Which of the following is NOT part of the cell theory?
Nonliving and living things are made of cells.
What is a major difference between prokaryotic and eukaryotic cells?
Prokaryotic cells do not have membrane-bound structures.
A RBC is placed into a solution that is 37% solutes. The concentration of solutes inside the red blood cell is 42%. What will happen to the cell?
The cell will swell
How are the reactions for photosynthesis and cellular respiration related?
The glucose and oxygen produced in photosynthesis are used as reactants in aerobic cellular respiration.
How does a person's fitness level affect anaerobic respiration?
The more fit the person, the greater the time before anaerobic respiration is required.
A cell is placed into a salt solution. The salt concentration is greater in the solution than inside the cell. Which best describes what will most likely happen?
Water will flow out by passive transport.
The concentration of solutes differs on the two sides of a cell membrane that are permeable only to water. Which describes the movement of materials across the cell membrane?
Water will move by osmosis.
Which is responsible for muscle pain felt after repeatedly lifting weights?
a buildup of lactic acid due to anaerobic respiration
The cytoplasm is best described as...
a jelly like fluid that surrounds organelles
Which example best represents the semi-permeable nature of the cell membrane?
a security system that allows employees in and out with proper ID
Centrioles are found in what type of cell?
animal
Which structure could prevent a saltwater plant cell from bursting when the cell is placed into distilled water?
cell wall
Which of the following organelles does not go with the others? (Hint: think about organelles found in plant and animal cells)

The proper term for uncoiled DNA found free floating and not contained in a nucleus would be...
chromatin
What is the role of the nucleus?
direct the cells activities
Which occurs when ATP is formed?
energy is stored
What is the end result of diffusion across a cell's membrane?
equal concentrations of water on both the inside and outside of the cell
The organelle that packages and ships lipids and proteins to the plasma membrane is called the
golgi body
Which of the following organelle contains hydrolytic enzymes and is used to digest and remove worn out cell organelles?
lysosomes
Which organelle would be found in large quantities in muscle cells?
mitochondrion
Which accurately describes active transport?
movement of particles from a low concentration to a high concentration
That is the term that defines the barrier surround the nucleus?
nuclear membrane
Which organelle is responsible for producing ribosomes?
nucleolus
Which affects the rate of photosynthesis the least?
oxygen
DNA is found free-floating and unbound in which type of cell?
prokaryote
What is the function of ribosomes? (Hint, what do they produce?)
protein synthesis
Which organelle would be found in BOTH a prokaryotic and eukaryotic cell?
ribosomes
Chlorophyll is best described as...
the pigment found in the chloroplast
