Questions and Answers
  • 1. 

    What did Leeuwenhoek do?

    • A.

      Looked at cork

    • B.

      Stated that animals are made of cells

    • C.

      All plants are made of cells

    • D.

      Used simple light microscope and saw microorganisms

    Correct Answer
    D. Used simple light microscope and saw microorganisms
    Explanation
    Leeuwenhoek used a simple light microscope and observed microorganisms. This is supported by the fact that he is known as the "Father of Microbiology" and made significant contributions to the field by discovering and documenting various microorganisms, such as bacteria and protozoa, using his self-made microscopes.

    T.Schwann did which of the following?

    • A.

      He said that plants are not made of cells

    • B.

      Said that animals aren't made of cells

    • C.

      Stated that all plants have cell

    • D.

      Stated that all animals have cells

    Correct Answer
    D. 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 his observation that animals, like plants, are also made up of cells. This discovery helped to solidify the understanding that cells are the basic building blocks of all living things.

    Robert Hooke was...?

    • 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.

    • B.

      Said that al plants are multicellular

    • C.

      Said that the begining unit is always a cell

    • D.

      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 person to see a cell and named it a cell (a room). He observed cork and noticed a line of cells that resembled small rooms, leading him to coin the term "cell." This discovery was a significant milestone in the field of biology and laid the foundation for our understanding of cells as the basic unit of life.

    What did M. Schleiden find out?

    • A.

      All animal cells are made of cells

    • B.

      All animals have voting rights

    • C.

      All animal cell have different functions

    • D.

      All plants are made cells

    Correct Answer
    D. All plants are made cells
    Explanation
    M. Schleiden found out that all plants are made of cells.

    What does the Cell Theory state?

    • A.

      That all living things are made of cells

    • B.

      Every cell has only one nucleus

    • C.

      That plants cannot have cells

    • D.

      Animals are only one that have cells

    Correct Answer
    A. That all living things are made of cells
    Explanation
    The Cell Theory states that all living things are made of cells. This theory, proposed in the mid-19th century, revolutionized the understanding of biology by establishing that cells are the basic structural and functional units of life. It states that cells are the building blocks of all living organisms and that all cells arise from pre-existing cells. This theory laid the foundation for the field of cell biology and has been supported by numerous observations and experiments over the years.

  • 6. 

    Unicellular and Multicellular is?

    • A.

      1 cell; Multi: 2+ cells

    • B.

      2+ cells; Multi: 200 cells

    • C.

      4+ cells; Multi: 145.00 cells

    • D.

      None of the above

    Correct Answer
    A. 1 cell; Multi: 2+ cells
    Explanation
    The correct answer is 1 cell; Multi: 2+ cells. This answer accurately describes the difference between unicellular and multicellular organisms. Unicellular organisms are made up of only one cell, while multicellular organisms are composed of two or more cells. This explanation clearly states the correct answer without any unnecessary information.

    True or False? Cell is the basic unit of life...

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement "Cell is the basic unit of life" is true. Cells are the smallest structural and functional units of all living organisms. They are responsible for carrying out essential functions necessary for life, such as growth, reproduction, and metabolism. Cells contain genetic material, organelles, and a cell membrane that regulates the movement of substances in and out of the cell. All living organisms are made up of one or more cells, making the cell the fundamental building block of life.

  • 8. 

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

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    True. The organization of biological structures typically begins with cells, which then form tissues, organs, organ systems, and eventually complete organisms. This concept is known as the hierarchical organization of living organisms.

    True or False?  All cells don't come from pre-existing cells.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The answer is false because according to the cell theory, which is a fundamental principle in biology, all cells arise from pre-existing cells. This theory states that cells are the basic units of life and that new cells are formed through the division of pre-existing cells. This process is known as cell division and is essential for growth, development, and the maintenance of living organisms. Therefore, it is incorrect to say that all cells don't come from pre-existing cells.

    Which cell organelle is called as the power house of the cell?

    • A.

      Ribosomes

    • B.

      Mitochondria

    • C.

      Lysosomes

    • D.

      Endoplasmic Reticulation

    Correct Answer
    B. Mitochondria
    Explanation
    Mitochondria is called the power house of the cell because it is responsible for producing the majority of the cell's energy in the form of ATP (adenosine triphosphate) through cellular respiration. This organelle contains its own DNA and is involved in various metabolic processes, including the breakdown of carbohydrates and fatty acids to generate energy. Without mitochondria, cells would not have the necessary energy to carry out their functions, making it an essential organelle for cellular survival and functioning.
