Multiple Choice
In the history of cell biology, which set correctly lists the three classical tenets of cell theory?
A
All living organisms are composed of one or more cells; the cell is the basic unit of structure and function in living things; all cells arise from pre-existing cells.
B
All cells contain a nucleus; all organisms are multicellular; cells arise spontaneously from nonliving matter.
C
All living organisms are composed of tissues; the tissue is the basic unit of life; all tissues arise from pre-existing tissues.
D
Cells are the basic unit of heredity; all cells arise only from abiotic chemicals; all organisms are composed solely of proteins.
Verified step by step guidance1
Recall the three classical tenets of cell theory, which are fundamental principles established in cell biology.
First tenet: All living organisms are composed of one or more cells. This means that cells are the building blocks of all life forms.
Second tenet: The cell is the basic unit of structure and function in living things. This emphasizes that cells carry out all necessary life processes.
Third tenet: All cells arise from pre-existing cells. This rejects the idea of spontaneous generation and highlights cell division as the source of new cells.
Compare each option in the problem to these three tenets to identify the correct set that matches all three principles.
