About This 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.

    What is the function of the nucleus?

    • Storage for nutrients

    • Control center for cell

    • Makes energy

    • Photosynthesizes

    Correct Answer
    A. Control center for cell
    Explanation
    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.

    What is the nutritious goo(or gel-like substance)inside cells called?

    • Chloroplasts

    • Nucleus

    • Cytoplasm

    • Cellojello

    Correct Answer
    A. Cytoplasm
    Explanation
    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.

    Which organelle creates ATP energy for a cell?

    • Chloroplast

    • Mitochondria

    • Ribosome

    • Nucleus

    Correct Answer
    A. Mitochondria
    Explanation
    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.

    What are the most important parts of chromosomes?

    • DNA

    • Proteins

    • Lipids

    • carbohydrates

    Correct Answer
    A. DNA
    Explanation
    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.

    Where does photosynthesis happen?

    • Chloroplasts

    • Ribosomes

    • Mitochondria

    • Vacuoles

    Correct Answer
    A. Chloroplasts
    Explanation
    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.

  • 7. 

    What is the function of chloroplasts?

    • Makes sugar from sunlight

    • Creates energy for the cell

    • Holds the DNA

    • Is used for storage

    Correct Answer
    A. Makes sugar from sunlight
    Explanation
    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.

    Plant cells and animal cells both possess this organelle. It is used to store water and food.

    • Nucleus

    • Mitochondria

    • Vacuole

    • Cytoplasm

    Correct Answer
    A. Vacuole
    Explanation
    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.

  • 9. 

    Which of the following organelles do animal cells have?

    • Chloroplasts

    • Cell wall

    • Chlorophyll

    • Mitochondria

    Correct Answer
    A. Mitochondria
    Explanation
    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.

  • 10. 

    Which description best fits the cell membrane?

    • Transparent

    • Rigid for support

    • Thick and waxy

    • Semi-permeable

    Correct Answer
    A. Semi-permeable
    Explanation
    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.

    Which of the following organelles is shown above? - ProProfs

    Which of the following organelles is shown above?

    • Vacuole

    • Nucleus

    • Chloroplast

    • Mitochondria

    Correct Answer
    A. Chloroplast
    Explanation
    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.

    Animal cells do not have...

    • Chloroplasts

    • Cell walls

    • A squarish shape

    • A large central vacuole

    • They have none of the above

    Correct Answer
    A. They have none of the above
    Explanation
    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.
