As Level Eukaryotic Cells Test - Quiz
About This Quiz

In this AS Level Eukaryotic Cells test, we’ll be taking a look at these cells which have plasma membranes, cytoplasm and ribosomes. What, however, sets eukaryotic cells apart from their prokaryotic counterparts? That’s for you to tell us! Let’s see what you know right now!

    Eukaryotic refers to

    • Without a nucleus

    • Bacteria cells

    • Simple cell

    • With a nucleus

    Correct Answer
    A. With a nucleus
    Explanation
    The term "eukaryotic" refers to organisms that have cells with a nucleus. In eukaryotic cells, the genetic material is contained within a membrane-bound nucleus, which separates it from the rest of the cell. This is in contrast to prokaryotic cells, such as bacteria, which do not have a nucleus. Eukaryotic cells are typically more complex than prokaryotic cells and are found in plants, animals, fungi, and protists. The presence of a nucleus is a defining characteristic of eukaryotic cells.

    How are ribosomes and endoplasmic reticulum linked?

    • Transport non protein products through the cell

    • Break down foreign objects in the cell

    • Synthesis and transport of proteins

    • Break down and transport proteins through the cell

    Correct Answer
    A. Synthesis and transport of proteins
    Explanation
    Ribosomes and endoplasmic reticulum are linked through the process of synthesis and transport of proteins. Ribosomes, which are responsible for protein synthesis, are found either free in the cytoplasm or attached to the endoplasmic reticulum. The endoplasmic reticulum, specifically the rough endoplasmic reticulum, is studded with ribosomes and plays a crucial role in protein synthesis and transport. It provides a platform for the ribosomes to synthesize proteins and then helps in the folding, modification, and transport of these proteins to their final destinations within the cell or outside of it.

    Which organelles are found in a eukaryotic cell?

    • Nucleus

    • Mitochondrion

    • Plasmid

    • A and B

    • A, B and C

    Correct Answer
    A. A and B
    Explanation
    The correct answer is A and B because the nucleus and mitochondrion are both organelles that are commonly found in eukaryotic cells. The nucleus is responsible for storing the cell's genetic material and controlling cellular activities, while the mitochondrion is involved in energy production through cellular respiration. Plasmid, on the other hand, is not an organelle found in eukaryotic cells, but rather a small, circular DNA molecule that is commonly found in bacteria.

    What is the function of the golgi body?

    • Transport of proteins for endocytosis

    • Transport of lipids for endocytosis

    • Transport proteins from the RER to the cell membrane for export

    • Transport lipids from the RER to the cell membrane for export

    Correct Answer
    A. Transport proteins from the RER to the cell membrane for export
    Explanation
    The Golgi body is responsible for modifying, sorting, and packaging proteins that are synthesized in the rough endoplasmic reticulum (RER). It receives proteins from the RER and processes them further by adding carbohydrates or lipids to form glycoproteins or lipoproteins. These modified proteins are then sorted and packaged into vesicles for transportation to the cell membrane, where they are eventually exported out of the cell. Therefore, the correct answer is "Transport proteins from the RER to the cell membrane for export."

    The cell membrane controls the .................... and exit of materials. 

    Correct Answer
    entry
    Explanation
    The cell membrane controls the entry and exit of materials. It acts as a selective barrier, allowing certain substances to enter the cell while preventing others from doing so. This regulation is crucial for maintaining the internal environment of the cell and ensuring proper functioning. By controlling the entry of materials, the cell membrane helps maintain homeostasis and protects the cell from potentially harmful substances.

    Lysosomes do what in eukaryotic cells?

    • Breakdown unwanted chemicals

    • Breakdown unwanted organelles

    • Allow the recycling of materials

    • Fuse with vacuoles

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    Lysosomes are membrane-bound organelles found in eukaryotic cells that are responsible for the breakdown of unwanted chemicals and organelles. They also play a crucial role in the recycling of materials by breaking them down into their basic components, which can then be reused by the cell. Additionally, lysosomes have the ability to fuse with vacuoles, which allows for the digestion of larger substances that have been engulfed by the cell. Therefore, the correct answer is "All of the above" as lysosomes perform all of these functions in eukaryotic cells.

    Chloroplasts also have a third membrane called the .......................... membrane

    Correct Answer
    thylakoid
    Explanation
    Chloroplasts are organelles found in plant cells that are responsible for photosynthesis. They have a double membrane, with the inner membrane forming structures called thylakoids. Thylakoids are flattened, membranous sacs that contain chlorophyll and other pigments necessary for capturing light energy. They are involved in the light-dependent reactions of photosynthesis, where the energy from sunlight is converted into chemical energy. The thylakoid membrane is where these reactions take place, and it plays a crucial role in the production of ATP and NADPH, which are used in the synthesis of glucose and other organic molecules.

    What are the functions of the Mitochondrion - ProProfs

    What are the functions of the Mitochondrion

    • Site of aerobic respiration

    • Glycolysis

    • Transduce light

    • Synthesise ATP

    Correct Answer(s)
    A. Site of aerobic respiration
    A. Synthesise ATP
    Explanation
    The mitochondrion is responsible for aerobic respiration, which is the process of converting glucose into energy in the presence of oxygen. This organelle contains enzymes and structures that facilitate the various steps of aerobic respiration, including the Krebs cycle and the electron transport chain. Additionally, the mitochondrion plays a crucial role in synthesizing ATP, the main energy currency of the cell. Through a series of chemical reactions, ATP is produced within the mitochondria and can be used by the cell for various metabolic processes. Therefore, the functions of the mitochondrion include being the site of aerobic respiration and synthesizing ATP.

    What statements best match the structure and function of the cell wall?

    • Is a thick layer outside the cell membrane

    • Used to give a cell strength and rigidity

    • Made mainly of disaccharides

    • Allows animal cells to exert turgor pressure

    • Is freely permeable

    Correct Answer(s)
    A. Is a thick layer outside the cell membrane
    A. Used to give a cell strength and rigidity
    A. Is freely permeable
    Explanation
    The cell wall is a thick layer that is located outside the cell membrane. It serves the purpose of providing strength and rigidity to the cell. Additionally, the cell wall is freely permeable, meaning that it allows substances to pass through it easily. However, it is important to note that the cell wall is not made mainly of disaccharides, as this statement is incorrect. Instead, the cell wall is primarily composed of polysaccharides such as cellulose in plant cells and peptidoglycan in bacterial cells.
