What Do You Know About Organelles? Trivia Questions Quiz
An organelle is a nanoscopic cellular structure within a cell that performs a specific function that is embedded within the cytoplasm of eukaryotic and prokaryotic cells. Organelles are responsible for generating energy and controlling the cell's growth and reproduction. This quiz has been designed to test your knowledge of the function of cellular organelles. Let's begin. All the best!
Questions and Answers
- 1.
The organelle that is responsible for breaking down old cells and waste materials, and removing those materials from the cells is.....
- A.
Mitochondria
- B.
Chloroplast
- C.
Lysosome
- D.
Ribosome
Correct Answer
C. LysosomeExplanation
The lysosome is responsible for breaking down old cells and waste materials, as well as removing those materials from the cells. It contains enzymes that break down various molecules, such as proteins, lipids, and carbohydrates, into smaller components that can be recycled or eliminated from the cell. This process is important for maintaining cellular homeostasis and preventing the accumulation of harmful waste materials. Mitochondria are responsible for energy production, chloroplasts are found in plant cells and are responsible for photosynthesis, and ribosomes are responsible for protein synthesis.Rate this question:

The _________________________ is the control center of the cell, directing all the functions of the cell.
- A.
Cell membrane
- B.
Nucleus
- C.
Endoplasmic reticulum
- D.
Mitochondria
Correct Answer
B. NucleusExplanation
The nucleus is the control center of the cell because it contains the cell's DNA, which carries the instructions for all the cell's functions. It directs the cell's activities by regulating gene expression and coordinating the production of proteins. The nucleus also plays a role in cell division and reproduction.Rate this question:

Pores in this organelle allow materials to pass in and out of the cell.
- A.
Endoplasmic reticulum
- B.
Golgi body
- C.
Cytoplasm
- D.
Cell membrane
Correct Answer
D. Cell membraneExplanation
The cell membrane is a semi-permeable barrier that surrounds the cell and regulates the passage of materials in and out of the cell. It is composed of a phospholipid bilayer with embedded proteins that form pores or channels. These pores allow for the selective movement of molecules, such as nutrients and waste products, across the membrane. Therefore, the cell membrane is responsible for controlling the exchange of materials between the cell and its surroundings.Rate this question:

These two organelles are responsible for passing the proteins through the cell and packaging them to leave the cell
- A.
Mitochondria and cytoplasm
- B.
Endoplasmic reticulum and golgi body
- C.
Cell membrane and nucleus
- D.
Snoopy and charlie brown
Correct Answer
B. Endoplasmic reticulum and golgi bodyExplanation
The endoplasmic reticulum and golgi body are responsible for passing proteins through the cell and packaging them to leave the cell. The endoplasmic reticulum is involved in the synthesis of proteins, while the golgi body modifies, sorts, and packages proteins into vesicles for transport. Together, these organelles play a crucial role in the intracellular transport and secretion of proteins.Rate this question:

Ribosomes are created in the ____________________________________.
- A.
Nucleolus
- B.
Ribosomes
- C.
Cell membrane
- D.
Cytoplasm
Correct Answer
A. NucleolusExplanation
Ribosomes are created in the nucleolus. The nucleolus is a small, dense region within the nucleus of a cell. It is responsible for producing and assembling ribosomal subunits, which then exit the nucleus and combine in the cytoplasm to form functional ribosomes. These ribosomes play a crucial role in protein synthesis, as they are the sites where mRNA is translated into proteins. Therefore, the nucleolus is the correct answer as it is the specific organelle within the cell where ribosomes are created.Rate this question:

What two organelles are found only in plant cells?
Correct Answer
cell wall and chloroplasts
chloroplasts and cell wall
cell wall and chloroplast
chloroplast and cell wallExplanation
The correct answer is cell wall and chloroplasts. Plant cells have a rigid cell wall made of cellulose, which provides structural support and protection. Chloroplasts are also found only in plant cells and are responsible for photosynthesis, converting sunlight into energy for the plant.Rate this question:

The organelle that is responsible for you looking the way you do is the
Correct Answer
chromatinExplanation
Chromatin is the correct answer because it plays a crucial role in determining our physical appearance. Chromatin is a complex of DNA, RNA, and proteins that make up our chromosomes. It contains all the genetic information that determines our traits, including our physical characteristics like eye color, hair color, and height. The way chromatin is organized and packaged in our cells influences which genes are expressed and ultimately shapes our physical appearance.Rate this question:

Jello like substance that holds the organelles in place throughout the cell
Correct Answer
cytoplasmExplanation
Cytoplasm is a jello-like substance that fills the cell and holds the organelles in place. It is a semi-fluid medium that surrounds the cell's nucleus and provides a medium for the movement of organelles and molecules within the cell. Cytoplasm also plays a vital role in maintaining the shape and structure of the cell, as well as facilitating various cellular processes such as metabolism and protein synthesis.Rate this question:

Cell organelles are located within the ____ of the cell.
- A.
Nucleus
- B.
Cytoplasm
- C.
Cell membrane
- D.
Lysosomes
Correct Answer
B. CytoplasmExplanation
Cell organelles are located within the cytoplasm of the cell. The cytoplasm is a gel-like substance that fills the cell and surrounds the organelles. It provides a medium for the organelles to carry out their functions and allows for the movement of molecules and organelles within the cell. The cytoplasm also contains various nutrients and enzymes that are necessary for the cell's metabolic processes. Therefore, the correct answer is cytoplasm.Rate this question:
