About This Quiz

A cell is the elemental unit of all living organisms that contain genetic data lying within DNA. Robert Hooke coined the term 'Cell' in 1665. Afterward, advanced theories were propounded by German Scientist Schwann and Schleiden. This quiz will assess your knowledge about cell theory, its discovery, and structure.

  • 2. 

    A cell is the basic unit of life.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement "A cell is the basic unit of life" is true because cells are the smallest structural and functional units of living organisms. They are responsible for carrying out all the necessary processes for life, such as metabolism, growth, and reproduction. Cells can be found in all living organisms, from single-celled organisms like bacteria to complex multicellular organisms like plants and animals. Without cells, life as we know it would not be possible.

    Rate this question:

  • 3. 

    Which technology was essential for the development of the cell theory?

    • Telescopes

    • Antiseptics

    • Microwaves

    • Microscopes

    Correct Answer
    A. Microscopes
    Explanation
    Microscopes were essential for the development of the cell theory because they allowed scientists to observe and study cells in detail. Before the invention of microscopes, cells were not visible to the naked eye, and their existence was not known. Microscopes enabled scientists like Robert Hooke and Anton van Leeuwenhoek to discover and describe cells, leading to the development of the cell theory, which states that all living organisms are composed of cells.

    Rate this question:

  • 4. 

    Robert Hooke was:

    • The 1st to see a cell, and named it a cell(a room); looked at cork; saw a line of cells that reminded him of rooms.

    • Said that al plants are multicellular

    • Said that the begining unit is always a cell

    • Was the 2nd person to see a man on earth

    Correct Answer
    A. The 1st to see a cell, and named it a cell(a room); looked at cork; saw a line of cells that reminded him of rooms.
    Explanation
    Robert Hooke was the first to see a cell and named it a cell (a room). He observed a piece of cork and noticed a line of cells that resembled rooms, leading him to coin the term "cell." This discovery was significant as it laid the foundation for the field of cell biology and our understanding of the basic unit of life.

    Rate this question:

  • 5. 

    All cells don't come from pre-existing cells.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    This statement contradicts the widely accepted principle of cell theory, which states that all cells arise from pre-existing cells. According to cell theory, cells are the fundamental units of life and can only be produced by the division of pre-existing cells. This process of cell division, known as mitosis, is responsible for the growth, development, and repair of all living organisms. Therefore, the correct answer is False.

    Rate this question:

  • 6. 

    The beginning unit is always a cell. it starts from cells to tissues to organs to organ system to organisms.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The given statement is true because in biology, the basic structural and functional unit of life is the cell. Cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms. This hierarchical organization allows for the specialization and coordination of different functions within an organism.

    Rate this question:

  • 7. 

    He advanced the cell theory with his conclusion that cells could only come from other cells.

    • Anton van Leeuwenhoek

    • Rudolph Virchow

    • Theodor Schwann

    • Robert Hooke

    Correct Answer
    A. Rudolph Virchow
    Explanation
    Rudolph Virchow advanced the cell theory by concluding that cells could only come from other cells. This concept, known as biogenesis, opposed the previous belief of spontaneous generation. Virchow's conclusion was based on his observations and experiments, which provided evidence that cells divide and give rise to new cells. This idea revolutionized the understanding of cellular reproduction and laid the foundation for modern cell biology.

    Rate this question:

  • 8. 

    What did Leeuwenhoek do?

    • Looked at cork

    • Stated that animals are made of cells

    • All plants are made of cells

    • Used simple light microscope and saw microorganisms

    Correct Answer
    A. Used simple light microscope and saw microorganisms
    Explanation
    Leeuwenhoek used a simple light microscope and observed microorganisms. This discovery was significant as it was the first time that microorganisms were observed and documented, leading to the development of the field of microbiology.

    Rate this question:

  • 9. 

    T.Schwann did which of the following?

    • He said that plants are not made of cells

    • Said that animals aren't made of cells

    • Stated that all plants have cell

    • Stated that all animals have cells

    Correct Answer
    A. Stated that all animals have cells
    Explanation
    T. Schwann stated that all animals have cells. This statement is in line with the cell theory, which states that all living organisms are composed of cells. Schwann's contribution to the cell theory was specifically focused on animal cells, as he observed and documented their presence in various animal tissues. His work, along with the contributions of other scientists, helped establish the fundamental understanding that cells are the basic building blocks of all living organisms.

    Rate this question:

  • 10. 

    Rudolph Virchow's observations helped to disprove was commonly held belief of the time?

    • Evolution

    • The existence of molecules

    • Spontaneous generation

    • Atomic models

    Correct Answer
    A. Spontaneous generation
    Explanation
    Rudolph Virchow's observations helped to disprove the commonly held belief of spontaneous generation at the time. Spontaneous generation was the belief that living organisms could arise spontaneously from non-living matter. Virchow's observations, particularly in the field of cellular pathology, supported the concept of biogenesis, which states that living organisms can only arise from pre-existing living organisms. His work on cell division and the theory of cell reproduction contributed to the rejection of spontaneous generation and the advancement of our understanding of how life originates.
