    What is the function of the lysosome?

    • To link chemicals

    • To provide a site for photosynthesis

    • To use stored enzymes to dissolve substances in a cell

    Correct Answer
    A. To use stored enzymes to dissolve substances in a cell
    Explanation
    The lysosome is an organelle responsible for breaking down and digesting various substances in a cell. It contains enzymes that can break down proteins, carbohydrates, lipids, and other molecules. These enzymes are stored within the lysosome until they are needed to break down substances such as worn-out organelles, foreign particles, or cellular waste. Therefore, the function of the lysosome is to use these stored enzymes to dissolve substances in a cell.

    The cell theory states that:

    • All living things are made up of atoms

    • Cell are formed from prexisting cells

    • Cell are made up of a nucleus

    Correct Answer
    A. Cell are formed from prexisting cells
    Explanation
    The Cell Theory states that:
    1. Cells are the basic units of structure and function in living things
    2. All living things are made up of cells
    3. New cells are created from preexisting cells

    The cell membrane contains fats and proteins

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The cell membrane is composed of a phospholipid bilayer, which consists of two layers of phospholipids. Phospholipids are a type of fat molecule that has a hydrophilic (water-loving) head and a hydrophobic (water-repelling) tail. These phospholipids form a barrier that separates the inside of the cell from its external environment. Additionally, the cell membrane also contains proteins that are embedded within the lipid bilayer or attached to its surface. These proteins have various functions, such as transporting molecules in and out of the cell, facilitating cell communication, and providing structural support. Therefore, the statement that the cell membrane contains fats and proteins is true.

    Proteins are large molecules made up of a series of amino acids. What is their main function?

    • Regulates the immune system

    • Helps regulate body temperature

    • Controls cell metabolism

    Correct Answer
    A. Controls cell metabolism
    Explanation
    Proteins play a crucial role in controlling cell metabolism. They act as enzymes, which are responsible for catalyzing various chemical reactions in cells. These reactions are essential for the breakdown of nutrients, synthesis of new molecules, and production of energy. Proteins also regulate the rate of these reactions, ensuring that they occur at the appropriate speed for proper cell function. Therefore, controlling cell metabolism is the main function of proteins.

    Golgi bodies which are 'flattened' scas shapd like a disc have what function?

    • Link, store and concentrate chemicals in the cytoplasm

    • Holds cell contents in shape

    • Provide a site for protein synthesis

    Correct Answer
    A. Link, store and concentrate chemicals in the cytoplasm
    Explanation
    Golgi bodies are concerned with:
    1. Linking chemicals, such as carbohydrates to proteins
    2. Storing chemicals
    3. Concentrating and secreting chemicals

    DNA and RNA are simple long chain molecules

    • True

    • False

    Correct Answer
    A. False
    Explanation
    DNA and rNA are complex long chain molecules

    Which of the following scientists proved that unless visited by flies, meat would not become infected by flies

    • Walter Flemming

    • Robert Hooke

    • Franceso Redi

    Correct Answer
    A. Franceso Redi
    Explanation
    Walter Flemming proved that cells come from pre-existing cells while Robert Hooke proved that all living organisms were made up of cells

    Advancements in glass lenses which allowed them to magnify up to 270 times resulted in what advancement to the cell theory

    • Robert Hooke discovering cells in a cork

    • Antoni van Leeuwenhoek discovered various cells in various organisms.

    • Development of the cell theory by Matthias Schleiden and Theodor Schwann

    Correct Answer
    A. Antoni van Leeuwenhoek discovered various cells in various organisms.
    Explanation
    The advancements in glass lenses that allowed them to magnify up to 270 times resulted in Antoni van Leeuwenhoek's discovery of various cells in various organisms. With the improved magnification capabilities, van Leeuwenhoek was able to observe and describe microscopic organisms, including bacteria and protozoa, for the first time. This discovery contributed to the development of the cell theory by Matthias Schleiden and Theodor Schwann, who further expanded upon the concept of cells as the basic unit of life.

    Ernst Abbe invented what technique in 1873?

    • Staining cells

    • Oil immersion

    • Dissecting

    Correct Answer
    A. Oil immersion
    Explanation
    In 1873, Ernst Abbe invented the technique of oil immersion. Oil immersion is a method used in microscopy where a drop of oil is placed between the objective lens and the specimen. This technique helps to increase the resolution and clarity of the image by reducing the refraction of light. By using oil immersion, the numerical aperture of the lens is increased, allowing for better visualization of fine details and improving the overall quality of the microscopic image.
