Which of the following is not a major idea in the cell theory?

All cells are composed of one or more cells
Cells are the basic unit of structure and organization in all living things
Cells are so small that we know very little about them
Cells arise only from previously existing cell and they pass genetic material to daughter cells

Correct Answer

A. Cells are so small that we know very little about them

Explanation

The correct answer is "Cells are so small that we know very little about them." This statement is not a major idea in the cell theory because the cell theory actually states that cells are the basic unit of structure and organization in all living things, and that all cells arise from previously existing cells and pass genetic material to daughter cells. The size of cells is not a major focus in the cell theory.

Which scientist determined that cells come from the division of other cells or preexisting cells?

Matthias Schleiden
Robert Hooke
Theodore Schwann
Rudolph Virchow
None of the above

Correct Answer

A. Rudolph Virchow

Explanation

Rudolph Virchow determined that cells come from the division of other cells or preexisting cells. This concept, known as cell division, is a fundamental principle in cell biology and was proposed by Virchow in the 19th century. He stated that all cells arise from preexisting cells, contradicting the previously held belief of spontaneous generation. Virchow's work laid the foundation for the cell theory, which states that cells are the basic units of life and all living organisms are composed of cells.

Which scientist discovered that animal tissues consist of individual cells?

Matthais Schleiden
Robert Hookes
Theodore Schwann
Rudolph Virchow
None of the Above

Correct Answer

A. Theodore Schwann

Explanation

Theodore Schwann is the correct answer because he is credited with discovering that animal tissues consist of individual cells. He made this discovery in the 1830s while studying animal tissues under a microscope. Schwann's work, along with the research of Matthias Schleiden on plant tissues, led to the formulation of the cell theory, which states that all living organisms are composed of cells. Robert Hooke, although an important scientist in the field of microscopy, is known for his observations of cells in plant tissues, not animal tissues. Rudolph Virchow, on the other hand, is known for his work on cell division and the theory of biogenesis.

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. Cells are the smallest structural and functional unit of living organisms. They are responsible for carrying out all the necessary processes of life, such as metabolism, growth, and reproduction. Cells can vary in size and shape, but they all have certain features in common, such as a cell membrane, genetic material, and the ability to perform biochemical reactions. Without cells, life as we know it would not exist.

All cells come from pre-existing cells.

True
False

Correct Answer

A. True

Explanation

This statement is a fundamental principle of the cell theory, which states that all living cells arise from pre-existing cells. This principle, first articulated by Rudolf Virchow in the mid-19th century, underpins modern biology and explains how cells reproduce and maintain continuity in living organisms.

8.

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

Microscopes
Telescopes
Scientists

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. Prior to the invention of microscopes, cells were not visible to the naked eye, making it impossible to understand their structure and function. With the use of microscopes, scientists were able to discover and describe the existence of cells, leading to the development of the cell theory.
