Ch. 1 SEC. 2 Eukaryotic Cells (Science) - Quiz


This quiz gives you full information on eukaryotic cells and their organelles. Chapter 1 of science textbook titled Cells: The Basic Units of Life.


Questions and Answers
  • 1. 

    Plant cells have an outermost structure that give support to the cell, known as

    • A.

      Cell membrane

    • B.

      Endoplasmic reticulum

    • C.

      cell wall

    • D.

      Vacuole

    Correct Answer
    C. cell wall
    Explanation
    Plant cells have an outermost structure called the cell wall, which provides support and protection to the cell. Unlike animal cells, plant cells have a rigid cell wall made up of cellulose. This structure helps maintain the shape of the cell and prevents it from bursting or collapsing under pressure. The cell wall also allows plants to grow upright and provides mechanical strength. Additionally, the cell wall acts as a barrier, regulating the movement of substances in and out of the cell. Therefore, the correct answer is cell wall.

    The organelle that packages and distributes proteins is called

    • A.

      Mitochondria

    • B.

      Golgi Complex

    • C.

      Ribosomes

    • D.

      The cell wall

    Correct Answer
    B. Golgi Complex
    Explanation
    The Golgi Complex is responsible for packaging and distributing proteins within the cell. It receives proteins from the endoplasmic reticulum and modifies them before they are packaged into vesicles and transported to their final destinations. This organelle plays a crucial role in the sorting and processing of proteins, ensuring that they are properly delivered to different parts of the cell or secreted outside. Therefore, the Golgi Complex is the correct answer for the organelle that packages and distributes proteins.

    The only difference between eukaryotic and prokaryotic cells is that eukaryotes have a nucleus and prokaryotes don't. (True or False)

    • A.

      T

    • B.

      F

    Correct Answer
    A. T
    Explanation
    Eukaryotic cells and prokaryotic cells differ in the presence of a nucleus. Eukaryotes have a well-defined nucleus that houses their genetic material, while prokaryotes lack a nucleus and their genetic material is dispersed throughout the cell. This distinction is the only difference between these two types of cells, making the statement true.

    A web of proteins that acts as a muscle and a skeleton is the

    • A.

      Cytoskeleton

    • B.

      Ribosome

    • C.

      Endoplasmic reticulum

    • D.

      Nucleolus

    Correct Answer
    A. Cytoskeleton
    Explanation
    The cytoskeleton is a web of proteins that provides structural support and helps in the movement of cells. It acts as both a muscle and a skeleton by allowing cells to change shape and move. It also helps in maintaining the overall shape of the cell and provides a framework for cellular processes. The ribosome is responsible for protein synthesis, the endoplasmic reticulum is involved in protein and lipid synthesis, and the nucleolus is responsible for the production of ribosomes. Therefore, the correct answer is cytoskeleton.

    The organelle, cholorplasts, which is located only in plant cells, 

    • A.

      Makes ribosomes

    • B.

      Performs photosynthesis

    • C.

      Delivers packages of proteins to the Golgi complex

    Correct Answer
    B. Performs photosynthesis
    Explanation
    Chloroplasts are organelles found only in plant cells that are responsible for performing photosynthesis. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. This process is essential for the plant's survival as it provides energy for growth and development. Therefore, the correct answer is that chloroplasts perform photosynthesis.

  • 6. 

    Lysosomes are organelles that contain digestive enzymes. They destroy worn out or damaged organelles and get rid of waste. (True or False)

    • A.

      T

    • B.

      F

    Correct Answer
    A. T
    Explanation
    Lysosomes are indeed organelles that contain digestive enzymes. These enzymes help in breaking down and recycling cellular waste, including worn out or damaged organelles. Therefore, the statement is true.

    Rate this question:

  • 7. 

    The liquid substance inside cells that holds all of the organelles in place is known as (the)

    • A.

      Lipid

    • B.

      Cell wall

    • C.

      Cellulose

    • D.

      Cytoplasm

    Correct Answer
    D. Cytoplasm
    Explanation
    The liquid substance inside cells that holds all of the organelles in place is known as cytoplasm. This is where various cellular processes occur, such as metabolism and protein synthesis. It is composed of water, salts, and organic molecules, and provides a medium for the movement and transportation of substances within the cell. The cytoplasm also helps maintain the shape and structure of the cell.

    Rate this question:

  • 8. 

    The organelle that stores water and other materials is known as (the)

    • A.

      Mitochondrion

    • B.

      Lysosome

    • C.

      Large central vacuole

    • D.

      Nucleus

    Correct Answer
    C. Large central vacuole
    Explanation
    The large central vacuole is the organelle that stores water and other materials in a cell. It is found in plant cells and is responsible for maintaining turgor pressure, which helps to support the cell and maintain its shape. The vacuole also stores various molecules, ions, and waste products. It plays a crucial role in regulating the cell's internal environment and maintaining homeostasis. The mitochondrion is responsible for energy production, the lysosome is involved in intracellular digestion, and the nucleus contains the cell's genetic material.
