  • Who first coined the term 'cell' in biology, and what was he observing when he did so?
    Robert Hooke first coined the term 'cell' while observing cork tissue under a homemade microscope in the mid-1600s.
  • What major improvement did Anton Van Leeuwenhoek make in the study of cells, and what did he observe?
    Anton Van Leeuwenhoek improved microscope magnification to about 300x, allowing him to observe live cells in substances like pond water, blood, and sperm.
  • What are the three main tenets of cell theory established in the 1800s?
    The three main tenets of cell theory are: all organisms are composed of one or more cells, the cell is the basic unit of life, and all cells arise from pre-existing cells.
  • What are the three main fields of modern cell biology, and what does each study?
    The three main fields are cytology (study of cell structure), biochemistry (study of cell structure and function), and genetics (study of genetic material storage and propagation).
  • How do hypotheses, theories, and laws differ in the scientific method as applied to cell biology?
    A hypothesis is a testable statement, a theory is a hypothesis that has been extensively tested and supported, and a law is a theory that has been confirmed over a long period without contradiction.

  • What was Anton van Leeuwenhoek's contribution to cell theory?
    Anton van Leeuwenhoek was the first to visualize live cells using a microscope with higher magnification, observing living cells in substances like pond water, blood, and sperm.
  • What was Rudolf Virchow's contribution to cell theory?
    Rudolf Virchow contributed to cell theory by stating that cells arise only from pre-existing cells, adding the third tenet to the theory.
  • How did Rudolf Virchow contribute to the cell theory?
    Rudolf Virchow contributed by establishing that cells can only arise by division from pre-existing cells.
  • What are the three key points of cell theory?
    The three key points are: all organisms are composed of one or more cells, the cell is the basic unit of life, and cells arise only from pre-existing cells.
  • Which statement is NOT a part of the cell theory?
    Any statement suggesting that cells can arise spontaneously or that living things are not made of cells is not part of cell theory.
  • Which statement is not part of the cell theory?
    Statements that contradict the three tenets, such as 'cells arise spontaneously' or 'organisms are not made of cells,' are not part of cell theory.
  • How did Antonie van Leeuwenhoek contribute to the cell theory?
    Antonie van Leeuwenhoek contributed by being the first to observe and describe live cells using a microscope with high magnification.
  • What did Rudolf Virchow contribute to the cell theory?
    Rudolf Virchow contributed the idea that cells arise only from pre-existing cells.
  • What was Leeuwenhoek's contribution to cell theory?
    Leeuwenhoek was the first to observe live cells, demonstrating that cells are living entities.
  • What did Leeuwenhoek contribute to the cell theory?
    He discovered and described live cells, advancing the understanding of cell biology.
  • What are the three main ideas of the cell theory?
    All organisms are made of one or more cells, the cell is the basic unit of life, and cells arise only from pre-existing cells.
  • Which is not part of the cell theory?
    Any claim that contradicts the three tenets, such as spontaneous generation of cells, is not part of cell theory.
  • Which of the following is not part of cell theory?
    Statements that do not align with the three tenets, such as 'cells arise spontaneously,' are not part of cell theory.
  • What are the three main ideas of cell theory?
    1. All organisms are composed of one or more cells. 2. The cell is the basic unit of life. 3. Cells arise only from pre-existing cells.
  • What are the main points of the cell theory?
    The main points are: all organisms are made of cells, the cell is the basic unit of life, and cells come from pre-existing cells.
  • What was Antonie van Leeuwenhoek's role in cell theory?
    He was the first to observe and describe live cells using a microscope.
  • What did Virchow contribute to the cell theory?
    Virchow contributed the principle that cells arise only from pre-existing cells.
  • What was Francesco Redi's contribution to cell theory?
    Francesco Redi's experiments helped disprove spontaneous generation, supporting the idea that life does not arise from non-living matter.
  • Which statement is part of the cell theory?
    All organisms are composed of one or more cells.
  • Which are the main points of the cell theory?
    1. All organisms are made of cells. 2. The cell is the basic unit of life. 3. Cells arise only from pre-existing cells.
  • Which was the first cell viewed by the light microscope?
    The first cells viewed by the light microscope were dead plant cells in cork, observed by Robert Hooke.
  • Which statement is part of cell theory?
    The cell is the basic unit of life.
  • Which is not true about the cell theory?
    It is not true that cells can arise spontaneously or that non-cellular entities are living.
  • Which statement is a part of the cell theory?
    Cells arise only from pre-existing cells.
  • Which statement is one component of the cell theory?
    All organisms are composed of one or more cells.
  • According to cell theory, which activity is impossible?
    According to cell theory, it is impossible for living cells to arise spontaneously from non-living matter.
  • Which of these is a component of cell theory?
    The cell is the basic unit of life.
