Multiple Choice
In the history of cell biology, which set correctly lists the three classical tenets of cell theory?
A
All cells have cell walls; the cell is the basic unit of heredity; all organisms are composed only of tissues.
B
All cells contain a nucleus; all organisms reproduce sexually; all cells arise spontaneously from nonliving matter.
C
Cells are the smallest observable structures; cells are identical in all organisms; all cells are formed by fusion of smaller particles.
D
All living organisms are composed of one or more cells; the cell is the basic unit of structure and function in organisms; all cells arise from pre-existing cells.
Verified step by step guidance1
Recall the historical development of cell theory, which is a fundamental concept in cell biology describing the properties of cells.
Identify the three classical tenets of cell theory: (1) All living organisms are composed of one or more cells; (2) The cell is the basic unit of structure and function in organisms; (3) All cells arise from pre-existing cells.
Compare each given option with these three tenets to check for accuracy and completeness.
Eliminate options that include incorrect statements such as 'all cells have cell walls' or 'cells arise spontaneously from nonliving matter,' which contradict established cell theory.
Confirm that the correct set matches exactly the three classical tenets of cell theory as historically defined.
