(183).jpg "Cell Organelles: Test Your GK! Quiz - Quiz")
How much do you know about cell organelles? Cytoplasmic organelles are little structures that are kept in the cytoplasm of the cell. Each type of organelle serves a different purpose concerning the function of the cell. Examples of cytoplasmic organelles are mitochondrion, ribosomes, endoplasmic reticulum, Golgi apparatus, chromosomes, nuclear membrane, nucleus, nucleolus, and lysosomes. This exciting quiz will put your knowledge of cell organelles to the test.
Questions and Answers
- 1.
Which organelle creates ATP energy for a cell?
- A.
Chloroplast
- B.
Mitochondria
- C.
Ribosome
- D.
Nucleus
Correct Answer
B. MitochondriaExplanation
Mitochondria are the organelles responsible for creating ATP energy in a cell. They are often referred to as the "powerhouses" of the cell because they produce the majority of the cell's energy. Through a process called cellular respiration, mitochondria convert nutrients into ATP, which is the energy currency of the cell. ATP is used for various cellular processes, including muscle contraction, active transport, and synthesis of macromolecules. Chloroplasts, on the other hand, are responsible for photosynthesis in plant cells, not ATP production. Ribosomes are involved in protein synthesis, while the nucleus contains the cell's genetic material.Rate this question:

What is the function of chloroplasts?
- A.
Makes sugar from sunlight
- B.
Creates energy for the cell
- C.
Holds the DNA
- D.
Is used for storage
Correct Answer
A. Makes sugar from sunlightExplanation
Chloroplasts are responsible for the process of photosynthesis, where they convert sunlight into energy in the form of sugar molecules. This energy-rich sugar is then used by the cell for various metabolic processes and to provide fuel for growth and development. Therefore, the function of chloroplasts is to make sugar from sunlight, enabling the cell to obtain energy for its activities.Rate this question:

Plant cells and animal cells both possess this organelle. It is used to store water and food.
- A.
Nucleus
- B.
Mitochondria
- C.
Vacuole
- D.
Cytoplasm
Correct Answer
C. VacuoleExplanation
Both plant cells and animal cells possess a vacuole, which is used to store water and food. The vacuole is a membrane-bound organelle that helps maintain the shape and structure of the cell, as well as regulate its internal environment. In plant cells, the vacuole is usually larger and plays a crucial role in maintaining turgor pressure, which helps the plant maintain its rigidity. In animal cells, the vacuole is typically smaller and is involved in various cellular processes such as storage, waste disposal, and maintaining homeostasis.Rate this question:

What are the most important parts of chromosomes?
- A.
DNA
- B.
Proteins
- C.
Lipids
- D.
carbohydrates
Correct Answer
A. DNAExplanation
The most important parts of chromosomes are DNA. DNA contains the genetic information that determines the characteristics and functions of living organisms. It carries the instructions for the development, growth, and reproduction of all living things. Proteins, lipids, and carbohydrates are important molecules in cells, but they are not the main components of chromosomes. Chromosomes are made up of DNA tightly coiled around proteins called histones.Rate this question:

Which description best fits the cell membrane?
- A.
Transparent
- B.
Rigid for support
- C.
Thick and waxy
- D.
Semi-permeable
Correct Answer
D. Semi-permeableExplanation
The cell membrane is best described as semi-permeable because it selectively allows certain substances to pass through while preventing others from entering or leaving the cell. This characteristic is essential for maintaining the cell's internal environment and regulating the movement of molecules in and out of the cell.Rate this question:

Which of the following organelles do animal cells have?
- A.
Chloroplasts
- B.
Cell wall
- C.
Chlorophyll
- D.
Mitochondria
Correct Answer
D. MitochondriaExplanation
Animal cells have mitochondria, which are organelles responsible for generating energy in the form of ATP through cellular respiration. This organelle is found in all animal cells and plays a crucial role in providing energy for various cellular processes. Chloroplasts, cell walls, and chlorophyll are typically found in plant cells, not animal cells.Rate this question:

What is the function of the nucleus?
- A.
Storage for nutrients
- B.
Control center for cell
- C.
Makes energy
- D.
Photosynthesizes
Correct Answer
B. Control center for cellExplanation
The nucleus is the control center for the cell. It contains the cell's DNA, which carries the instructions for the cell's activities and functions. The nucleus regulates gene expression and controls the synthesis of proteins, which are essential for the cell's structure and function. It also plays a role in cell division and reproduction. Overall, the nucleus acts as the command center, coordinating and controlling the cell's activities.Rate this question:

What is the nutritious goo(or gel-like substance)inside cells called?
- A.
Chloroplasts
- B.
Nucleus
- C.
Cytoplasm
- D.
Cellojello
Correct Answer
C. CytoplasmExplanation
Cytoplasm is the correct answer because it is the gel-like substance found inside cells that contains various organelles, such as the nucleus and mitochondria, as well as other nutrients and molecules necessary for cellular functions. Chloroplasts are responsible for photosynthesis in plant cells, while the nucleus is the control center of the cell. "Cellojello" is not a scientific term and does not exist in biology.Rate this question:

Where does photosynthesis happen?
- A.
Chloroplasts
- B.
Ribosomes
- C.
Mitochondria
- D.
Vacuoles
Correct Answer
A. ChloroplastsExplanation
Photosynthesis is the process by which plants convert sunlight into energy. It occurs in specialized organelles called chloroplasts, which contain chlorophyll. Chlorophyll absorbs light energy and uses it to convert carbon dioxide and water into glucose and oxygen. This process takes place in the chloroplasts' thylakoid membranes, where the necessary enzymes and pigments are located. Therefore, the correct answer is chloroplasts.Rate this question:

Animal cells do not have...
- A.
Chloroplasts
- B.
Cell walls
- C.
A squarish shape
- D.
A large central vacuole
- E.
They have none of the above
Correct Answer
E. They have none of the aboveExplanation
Animal cells do not have chloroplasts because chloroplasts are responsible for photosynthesis, which is the process by which plants convert sunlight into energy. Animal cells do not undergo photosynthesis. Animal cells also do not have cell walls, as cell walls are a characteristic feature of plant cells and provide structural support. Animal cells do not have a squarish shape, as they are typically irregular or rounded in shape. Lastly, animal cells do not have a large central vacuole, as vacuoles in animal cells are smaller and more dispersed compared to plant cells. Therefore, the correct answer is that animal cells have none of the above features.Rate this question:

Mitochondria
Correct Answer
D. MitochondriaExplanation
Mitochondria is the correct answer because it is an organelle found in most eukaryotic cells responsible for generating energy in the form of ATP through cellular respiration. It has a double membrane structure and contains its own DNA, allowing it to replicate independently within the cell. Mitochondria play a crucial role in metabolism and are often referred to as the "powerhouse" of the cell.Rate this question:

Which of the following organelles is shown above?
- A.
Vacuole
- B.
Nucleus
- C.
Chloroplast
- D.
Mitochondria
Correct Answer
C. ChloroplastExplanation
The correct answer is chloroplast because it is the only organelle mentioned in the options that is responsible for photosynthesis. Chloroplasts are found in plant cells and some algae, and they contain chlorophyll, which captures sunlight and converts it into energy through photosynthesis. The image shown above likely depicts a chloroplast due to its unique structure and the presence of thylakoid membranes, which are responsible for the light-dependent reactions of photosynthesis.Rate this question:
