Practice Test Questions
And Answers
1. If a cell is unable to perform endocytosis, what impact might this have on its
ability to acquire nutrients?
The cell would struggle to acquire essential nutrients and materials
necessary for survival.
The cell would increase its rate of exocytosis to compensate.
The cell would become more efficient at photosynthesis.
The cell would rely solely on diffusion for nutrient uptake.
2. What is the primary purpose of exocytosis in a cell?
Storing waste products
Removing materials from the cell
Synthesizing proteins
Transporting nutrients into the cell
3. Describe the significance of X-ray Crystallography in the study of molecular
biology.
X-ray Crystallography allows scientists to determine the three-
dimensional arrangement of atoms in a molecule.
X-ray Crystallography identifies the types of proteins present in a cell.
X-ray Crystallography measures the energy production in cells.
X-ray Crystallography is used to visualize living cells in real-time.
4. What is the definition of Tonicity?
, The concentration of dissolved solutes (Na and others) in your serum
Ability of the combined effect of all the solutes to generate an
osmotic driving force that causes H2O movement
Movement of water from an area of low concentration of solute to an
area of higher concentration of solute, in effort to create equilibrium
5. Which three components are essential for the process of photosynthesis?
O₂, glucose, and sunlight
CO₂, H₂O, and sunlight
CO₂, glucose, and oxygen
H₂O, O₂, and glucose
6. A meristem is
a region of active growth (persistent embryonic tissue) in which all
plant cells arise
a waxy layer formed by the epidermis
ground tissue at the center of a stem or root
an aggregate of cells that share a common function
7. Describe the role of the plant tip in the process of phototropism.
The tip of the plant produces chlorophyll for photosynthesis.
The tip of the plant detects light and sends signals to cause
bending.
The tip of the plant absorbs water and nutrients from the soil.
The tip of the plant anchors it to the ground.
,8. What is the primary role of transport proteins in cellular membranes?
Store genetic information.
Produce energy in the form of ATP.
Facilitate movement of larger molecules across membranes.
Synthesize proteins for cell structure.
9. What is the formula for photosynthesis?
6CO2 + 6H2O -(sun)-> C6H12O6 + 6O2
6O2 + 6H2O -(sun)-> C6H12O6 + 6CO2
6H2O + C6H12O6 -(sun)-> + 6O2+ 6CO2
C6H12O6 + 6CO2 -(sun)-> + 6O2+ 6CO2 + 6H2O
10. In what year did Robert Hooke coin the term 'cell'?
1665
1685
1675
1655
11. Who was Henrietta Lacks?
woman who fought in Washington for women's health issues
surrounding cancer of the breast, ovaries, and uterus.
famous cancer biologist who studied signal transduction and won the
Nobel Prize in Medicine.
woman who's cancer cells were grown in the lab for decades and
used to model cancer for numerous medical breakthroughs
, including COVID 19 vaccine.
12. If a cell's transport proteins were inhibited, what would be the most
immediate effect on the cell's function?
Increased energy production.
Improved cell adhesion.
Impaired movement of larger molecules across the membrane.
Enhanced protein synthesis.
13. Describe the concept of spontaneous generation and its significance in the
history of biology.
Spontaneous generation is the theory that all life comes from pre-
existing life forms.
Spontaneous generation refers to the process of plants growing from
seeds in soil.
Spontaneous generation is the belief that living organisms can
arise from non-living matter, which was a widely accepted idea
before being challenged by experiments.
Spontaneous generation is the concept that cells can only arise from
other cells.
14. What is the primary function of palisade tissue in plants?
Support structure
Nutrient absorption
Water storage
Main site of photosynthesis
