Which of the following statements is NOT part of the classical cell theory?
A
All cells arise from pre-existing cells.
B
The cell is the basic unit of structure and function in living organisms.
C
All living organisms are composed of one or more cells.
D
Cells arise spontaneously from nonliving matter under present-day conditions.
Verified step by step guidance1
Recall 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 function in living organisms, and (3) All cells arise from pre-existing cells.
Examine each statement given in the problem and compare it to these three tenets to determine if it aligns with classical cell theory.
Identify that the statement 'Cells arise spontaneously from nonliving matter under present-day conditions' contradicts the third tenet, which states that cells come only from pre-existing cells, not spontaneously.
Understand that spontaneous generation was a disproven concept and is not part of classical cell theory, which emphasizes continuity of life through cell division.
Conclude that the statement about spontaneous generation is NOT part of the classical cell theory, while the other statements are consistent with it.
