Questions and Answers
  • 1. 

    Is this activity helpful?  How do you know?

  • 2. 

    What is Diffusion?

    • A.

      Diffusion is the movement of molecules from low to high concentration with the help of ATP.

    • B.

      Diffusion is the movement of molecules from high to low concentration.

    • C.

      Diffusion is the movement of water molecules from low to high concentration.

    • D.

      Diffusion is the movement of molecules from low to high concentration.

    Correct Answer
    B. Diffusion is the movement of molecules from high to low concentration.
    Explanation
    Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. This process occurs naturally and does not require the input of ATP.

    What is the major difference between facilitated diffusion and active transport?

    • A.

      Facilitated diffusion uses large amounts of energy

    • B.

      Facilitated diffusion moves molecules through the plasma membrane

    • C.

      Active Transport uses proteins in the process

    • D.

      Active Transport moves substances against a concentration gradient with the help of ATP

    Correct Answer
    D. Active Transport moves substances against a concentration gradient with the help of ATP
    Explanation
    Active transport is a process that moves substances against their concentration gradient, meaning from an area of lower concentration to an area of higher concentration. This process requires the use of energy in the form of ATP (adenosine triphosphate). On the other hand, facilitated diffusion is a passive process that moves molecules across the plasma membrane from an area of higher concentration to an area of lower concentration. It does not require the use of energy. Therefore, the major difference between facilitated diffusion and active transport is that active transport moves substances against the concentration gradient with the help of ATP, while facilitated diffusion does not.

    What is osmosis?

    • A.

      The movement of molecules from low to high concentration

    • B.

      The movement of water from high to low concentration with the help of ATP

    • C.

      The movement of water from low to high concentration

    • D.

      The movement of water from high to low concentration without the help of ATP

    Correct Answer
    D. The movement of water from high to low concentration without the help of ATP
    Explanation
    Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration. This process occurs without the help of ATP, which is a molecule that provides energy for cellular processes. Therefore, the given answer correctly states that osmosis involves the movement of water from high to low concentration without the help of ATP.

    Rate this question:

  • 5. 

    The cells ability to let certain things in the cell and certain things out of the cell is called what?

    • A.

      Equalibrium

    • B.

      Selection

    • C.

      Selective Permeability

    • D.

      Active Transport

    Correct Answer
    C. Selective Permeability
    Explanation
    Selective permeability refers to the ability of a cell to control what substances can enter or exit the cell. This process is essential for maintaining homeostasis and regulating the cell's internal environment. The cell membrane plays a crucial role in selective permeability by allowing certain molecules to pass through while blocking others. This allows the cell to maintain a balance of nutrients, ions, and waste products, ensuring its proper functioning.
