Which of the following statements is part of the classical cell theory?
A
All living organisms are composed of one or more cells.
B
Cells can arise spontaneously from nonliving matter under the right conditions.
C
Mitochondria are the primary site of protein synthesis in all cells.
D
Hereditary information is stored in proteins rather than nucleic acids.
Verified step by step guidance1
Recall the classical cell theory, which is a fundamental concept in cell biology developed in the 19th century by scientists such as Schleiden, Schwann, and Virchow.
Identify the three main tenets of the classical cell theory: (1) All living organisms are composed of one or more cells, (2) The cell is the basic unit of structure and organization in organisms, and (3) All cells arise from pre-existing cells.
Evaluate each statement in the problem against these tenets: The statement 'All living organisms are composed of one or more cells' aligns directly with the first tenet of the classical cell theory.
Recognize that the statement 'Cells can arise spontaneously from nonliving matter under the right conditions' contradicts the third tenet, which states cells come from pre-existing cells, not spontaneous generation.
Understand that the other statements about mitochondria and hereditary information do not relate to the classical cell theory but rather to more specific cellular functions and molecular biology.
