    Correct Answer
    A. Gives the cell shape and protection and regulates the movement of substances into and out of the cell
    Explanation
    The cell membrane serves multiple functions in a cell. It provides shape and protection by enclosing the cell and acting as a barrier against external factors. It also regulates the movement of substances into and out of the cell, controlling the exchange of nutrients, waste products, and signaling molecules. The cell membrane contains various proteins and channels that facilitate the transport of specific molecules. Therefore, the correct answer is that the cell membrane gives the cell shape and protection and regulates the movement of substances into and out of the cell.

    Correct Answer
    A. Cytoplasm, and modify package and export
    Explanation
    The Golgi apparatus is located in the cytoplasm of the cell. Its main function is to modify, package, and export proteins. It receives proteins from the endoplasmic reticulum and processes them by adding sugars or lipids to them. It then packages these modified proteins into vesicles and transports them to their final destination within or outside the cell. Therefore, the Golgi apparatus plays a crucial role in the sorting, processing, and transportation of proteins within the cell.

    • D.

      In the nucleus, making ATP

    Correct Answer
    A. In the cytoplasm, photosynthesis and green pigment
    Explanation
    The chloroplast is responsible for photosynthesis and contains green pigments. It is located in the cytoplasm of the cell. Photosynthesis is the process by which plants convert sunlight into energy, and the chloroplast plays a crucial role in this process by capturing light energy and converting it into chemical energy. The green pigments, such as chlorophyll, are present in the chloroplast and are responsible for absorbing light energy. Therefore, the correct answer is that the function and location of the chloroplast are in the cytoplasm, photosynthesis, and green pigment.

    • D.

      All of the above

    Correct Answer
    A. In the cytoplasm, break down food and foreign material (ingest, digest, destroy)
    Explanation
    The correct answer is "in the cytoplasm, break down food and foreign material (ingest, digest, destroy)". Lysosomes are membrane-bound organelles found in the cytoplasm of cells. They contain digestive enzymes that break down various molecules, including food particles and foreign materials. Lysosomes play a crucial role in the process of digestion and waste removal within the cell. They help in breaking down complex substances into simpler forms that can be utilized by the cell for energy or eliminated as waste.

      Cyoplasm, movement

    • D.

      Chloroplast, rigidity

    Correct Answer
    A. Anchor to the cell membrane, help mobilize cells or mobilize the extracellular environment
    Explanation
    Cilia and flagella are hair-like structures found on the surface of cells. They anchor to the cell membrane and help in the movement of the cell. They are responsible for the locomotion of cells, such as the movement of sperm or the movement of mucus in the respiratory tract. Therefore, the correct answer is that cilia and flagella anchor to the cell membrane and help mobilize the cell.

    Rate this question:

  • 12. 

    Which is longer, cilia or flagella?

    • A.

      Cilia

    • B.

      Flagella

    Correct Answer
    B. Flagella
    Explanation
    Flagella are longer than cilia. Cilia are small, hair-like structures that are present on the surface of certain cells and are involved in movement. They are typically shorter and more numerous compared to flagella. Flagella, on the other hand, are longer whip-like structures that are also involved in cell movement. They are usually fewer in number and longer in length compared to cilia. Therefore, flagella are longer than cilia.

    • D.

      None of the above

    Correct Answer
    A. Outside cell, connect two cells
    Explanation
    Cell junctions are specialized structures that are located on the outside of the cell and their main function is to connect two adjacent cells together. These junctions provide mechanical support and help in maintaining the integrity of tissues. They also facilitate communication and exchange of molecules between cells. Therefore, the correct answer is "outside cell, connect two cells".

    Explanation
    The correct answer is mitochondria. Mitochondria are organelles that are responsible for energy conversions in cells. They are often referred to as the "powerhouses" of the cell because they produce the majority of the cell's energy in the form of ATP through a process called cellular respiration. This process involves the conversion of nutrients, such as glucose, into usable energy. Mitochondria have their own DNA and are believed to have originated from ancient bacteria that were engulfed by early eukaryotic cells.

    Correct Answer(s)
    A. Cytoskeleton
    B. Cell membrane
    Explanation
    The organelles associated with structural integrity are the cytoskeleton and the cell membrane. The cytoskeleton provides support and shape to the cell, while the cell membrane acts as a barrier and maintains the cell's structural integrity by controlling what enters and exits the cell. These organelles work together to ensure the cell maintains its shape and structure.

      Cytoskeleton

    Correct Answer
    C. Cytoskeleton
    Explanation
    Organelles associated with movement in cells include structures like cilia and flagella, which are responsible for cellular locomotion. However, the cytoskeleton, which includes microfilaments, microtubules, and intermediate filaments, plays a central role in providing structural support to the cell and facilitating various cellular movements such as cell division, cell shape changes, and intracellular transport. Therefore, the cytoskeleton is the organelle most directly associated with movement in cells.

    • D.

      Cytoplasm

    Correct Answer
    A. Cell junction
    Explanation
    Organelles associated with cell-to-cell connections are called cell junctions. Cell junctions are specialized structures that allow cells to adhere to each other and communicate with each other. They play a crucial role in maintaining the integrity and functionality of tissues and organs. Different types of cell junctions include tight junctions, adherens junctions, desmosomes, and gap junctions. These junctions provide mechanical support, regulate the passage of molecules between cells, and facilitate cell signaling.
