Structures of a Cell Questions and Answers
- 1.
What is the membrane-bound organelle that converts fuel into energy available to the rest of the cell?
- A.
Ribosome
- B.
Lysosome
- C.
Nucleus
- D.
Mitochondrion
Correct Answer
D. MitochondrionExplanation
The correct answer is mitochondrion. Mitochondria are membrane-bound organelles found in most eukaryotic cells. They are often referred to as the "powerhouses" of the cell because they are responsible for converting fuel, such as glucose, into energy in the form of adenosine triphosphate (ATP). This energy is then used by the rest of the cell for various cellular processes.Rate this question:

- A.
Flagellum
- B.
Cell wall
- C.
Centriole
- D.
Nucleolus
Correct Answer
B. Cell wallExplanation
The correct answer is cell wall. In plants, the cell wall is a rigid barrier that surrounds the outside of the plasma membrane. It is made of cellulose and provides support and structure to the cell. The cell wall helps maintain the shape of the cell and protects it from external stresses.Rate this question:

What is the membrane-bound vesicle for temporary storage of materials such as food, enzymes, and wastes?
- A.
Vacuole
- B.
Golgi apparatus
- C.
Cytoskeleton
- D.
Ribosome
Correct Answer
A. VacuoleExplanation
A vacuole is a membrane-bound vesicle that serves as a temporary storage organelle in cells. It can store various materials such as food, enzymes, and wastes. Vacuoles are commonly found in plant cells and some types of animal cells. They play a crucial role in maintaining cell turgor pressure, storing nutrients, and regulating waste disposal. The Golgi apparatus is responsible for modifying, sorting, and packaging proteins, while the cytoskeleton provides structural support and helps with cell movement. Ribosomes are involved in protein synthesis.Rate this question:

What is, in eukaryotic cells, the central, membrane-bound organelle that manages cellular functions and contains DNA?
- A.
Ribosome
- B.
Chloroplast
- C.
Ribosome
- D.
Nucleus
Correct Answer
D. NucleusExplanation
The correct answer is nucleus. The nucleus is the central, membrane-bound organelle in eukaryotic cells that manages cellular functions and contains DNA. It acts as the control center of the cell, regulating gene expression and coordinating cell activities. The nucleus is surrounded by a double membrane called the nuclear envelope and contains the nucleolus, which is responsible for producing ribosomes.Rate this question:

What is a vesicle that uses enzymes to digest excess or worn-out cellular substances?
- A.
Mitochondrion
- B.
Lysosome
- C.
Ribosome
- D.
Cell wall
Correct Answer
B. LysosomeExplanation
A lysosome is a vesicle that uses enzymes to digest excess or worn-out cellular substances. It acts as the recycling center of the cell, breaking down and recycling cellular waste materials. The enzymes within the lysosome are capable of breaking down various molecules, including proteins, lipids, and carbohydrates. This process helps maintain the overall health and functioning of the cell by removing and recycling unwanted materials.Rate this question:

What is a double-membrane organelle that captures light energy and converts it to chemical energy through photosynthesis
- A.
Nucleolus
- B.
Mitochondria
- C.
Chloroplast
- D.
Ribosome
Correct Answer
C. ChloroplastExplanation
A chloroplast is a double-membrane organelle that captures light energy and converts it to chemical energy through photosynthesis. It contains chlorophyll, a pigment that absorbs light and initiates the process of photosynthesis. This organelle is found in plants and some protists, and it is responsible for producing glucose and oxygen, which are essential for the survival of these organisms. The nucleolus is involved in the production of ribosomes, mitochondria are responsible for energy production, and ribosomes are involved in protein synthesis.Rate this question:

What is a highly folded membrane system in eukaryotic cells that is the site for ribosome attachment?
- A.
Endoplasmic reticulum
- B.
Golgi apparatus
- C.
Lysosome
- D.
Cell wall
Correct Answer
A. Endoplasmic reticulumExplanation
The endoplasmic reticulum is a highly folded membrane system in eukaryotic cells that serves as the site for ribosome attachment. This organelle plays a crucial role in protein synthesis and modification, as well as lipid metabolism and calcium storage. The extensive folding of the endoplasmic reticulum increases its surface area, allowing for more ribosomes to attach and more proteins to be produced. This membrane system is interconnected throughout the cell, forming a network of tubules and sacs that transport molecules within the cell. Therefore, the endoplasmic reticulum is the correct answer to the question.Rate this question:

What is a simple cell organelle that helps manufacture proteins?
- A.
Cell
- B.
Ribosome
- C.
Lysosome
- D.
Mitochondria
Correct Answer
B. RibosomeExplanation
Ribosomes are small, simple cell organelles that play a crucial role in protein synthesis. They are responsible for translating the genetic information from DNA into proteins. Ribosomes are found in both prokaryotic and eukaryotic cells and can be free-floating in the cytoplasm or attached to the endoplasmic reticulum. They consist of two subunits, large and small, which work together to read the mRNA and assemble amino acids into a polypeptide chain. Therefore, ribosomes are the correct answer as they are directly involved in the manufacturing of proteins within the cell.Rate this question:

Who discovered the cell?
Correct Answer
Robert Hooke
HookeExplanation
Robert Hooke is credited with the discovery of the cell. He was an English scientist who observed and described the structure of cells in cork under a microscope in 1665. Hooke's observations and drawings of the tiny compartments resembling honeycomb cells led to the term "cell" being used to describe the basic unit of life. His work laid the foundation for the field of cell biology and greatly contributed to our understanding of the microscopic world.Rate this question:
- 10.
The basic unit of life is the ___________.
Correct Answer
cell
cellsExplanation
The basic unit of life is the cell. Cells are the smallest structural and functional units of living organisms. They are capable of carrying out all the necessary processes for life, such as growth, reproduction, and metabolism. Cells can exist as single-celled organisms or as building blocks of complex multicellular organisms. They contain various organelles that perform specific functions within the cell. Overall, cells are fundamental to the existence and functioning of all living organisms.Rate this question:
- 11.
The prokaryote cell is _________ and smaller than a eukaryote cell.
Correct Answer
simpler
more simpleExplanation
The correct answer is "simpler." Prokaryote cells are simpler in structure compared to eukaryote cells. They lack a nucleus and membrane-bound organelles, while eukaryote cells have these structures. The answer "more simple" is incorrect because the comparative form of the adjective "simple" is "simpler."Rate this question:
- 12.
The word "cell" comes from the Latin word ________ meaning small room.
Correct Answer
cellulaExplanation
The word "cell" comes from the Latin word "cellula" which means small room.Rate this question:
- 13.
Where are prokaryotic cells found?
- A.
In bacteria and archaea
- B.
In protists, fungi, plants, animals
- C.
None of the above
Correct Answer
A. In bacteria and archaeaExplanation
Prokaryotic cells are found in bacteria and archaea. Bacteria and archaea are both types of microorganisms that lack a membrane-bound nucleus and other membrane-bound organelles. They are unicellular organisms that have a simple cellular structure. Prokaryotic cells can be found in various environments, including soil, water, and the human body. They play crucial roles in various ecological processes and are essential for maintaining the balance of ecosystems.Rate this question:
