BIOL 1107 EXAM PRE-CLASS QUIZ QUESTIONS
The cell theory is a fundamental principle in biology that describes the
basic characteristics and organization of living organisms. Which of the
following statements best describes the cell theory?
A. The cell theory states that cells are the basic units of life and all living
organisms are made up of cells.
B. The cell theory explains the process of photosynthesis in plant cells.
C. The cell theory states that cells are only present in eukaryotic
organisms.
D. The cell theory proposes that all cells have a nucleus. - ANS -A. The
cell theory states that cells are the basic units of life and all living
organisms are made up of cells.
The cell theory was formulated in the mid-19th century by scientists
Matthias Schleiden and Theodor Schwann, and later expanded upon by
Rudolf Virchow. It revolutionized our understanding of the organization
and functioning of living organisms, providing a framework for studying
cellular biology and advancing numerous fields of science and medicine.
The cell theory does not include which of the following concepts?
A. All living organisms are made of cells.
,B. Cells are the basic units of life.
C. Cells can spontaneously generate from non-living matter.
D. Cells carry out all the functions necessary for life. - ANS -C. Cells can
spontaneously generate from non-living matter.
Sarah, a biology student, is conducting a research project on cell
structure and function. She is particularly interested in understanding
the roles of the plasma membrane and cytoplasm in maintaining cell
integrity and regulating cellular processes. To explore this further, Sarah
conducts a comparative analysis of these two components.
Based on the scenario, how can Sarah compare and contrast the
functions of the plasma membrane and the cytoplasm in a cell, and
understand their collaborative role in maintaining cell integrity and
regulating cellular processes?
A. Sarah can examine how the plasma membrane regulates the
movement of substances in and out of the cell, while the cytoplasm
provides a medium for cellular reactions to occur.
B. Sarah can investigate how the plasma membrane stores genetic
material, while the cytoplasm synthesizes proteins.
C. Sarah can analyze how the plasma membrane protects the nucleus, -
ANS -A. Sarah can examine how the plasma membrane regulates the
movement of substances in and out of the cell, while the cytoplasm
provides a medium for cellular reactions to occur.
,A group of scientists is investigating the common characteristics shared
by all cells. They aim to compare and contrast these characteristics to
gain a better understanding of cellular biology. Based on their research,
which of the following statements accurately compares and contrasts
the common characteristics of all cells?
A. All cells have a nucleus that houses the genetic material, while only
some cells possess a plasma membrane as a protective barrier.
B. All cells contain cytoplasm, which is a gel-like substance, but their
size and shape can vary greatly.
C. The presence of ribosomes is a unique feature of prokaryotic cells,
while eukaryotic cells contain DNA as their genetic material.
D. Cells carry out metabolic activities, but the plasma membrane only
serves as a physical boundary, lacking any regulatory functions. - ANS -
B. All cells contain cytoplasm, which is a gel-like substance, but their
size and shape can vary greatly.
Why is surface area to volume ratio an important factor in cell size?
A. It determines the number of organelles present in a cell.
B. It influences the speed of cellular respiration.
C. It affects the rate of diffusion and transport of substances into and
out of the cell.
, D. It determines the shape and structural integrity of the cell. - ANS -C.
It affects the rate of diffusion and transport of substances into and out
of the cell.
Plant cells and animal cells are both eukaryotic cells, meaning they have
a membrane-bound nucleus and other membrane-bound organelles.
However, there are several key differences between plant cells and
animal cells in terms of their structures and functions. Which of the
following organelles is present in animal cells but absent in plant cells?
A. Centrosome
B. Mitochondria
C. Cell wall
D. Chloroplasts - ANS -A. Centrosome
Analyze the poem to answer the question below.
In a cell, a place of wonder,
Where energy's transformed like thunder,
Stored within macromolecules' grasp,
To ATP, a form that lasts.
Its membrane, oh so intricately folded,
