In the history of cell biology, which option correctly lists the three classic 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 cells contain mitochondria; all cells have a rigid cell wall.
C
Cells can arise spontaneously from nonliving matter; the nucleus is the basic unit of life; organisms are composed only of tissues.
D
All organisms are made of molecules; the atom is the basic unit of life; new organisms arise only from genetic recombination.
Verified step by step guidance1
Recall that the cell theory is a fundamental principle in cell biology that describes the properties and origins of cells.
Identify the three classic tenets of cell theory, which are historically established and widely accepted in biology.
The first tenet states that all living organisms are composed of one or more cells, emphasizing that cells are the building blocks of life.
The second tenet states that the cell is the basic unit of structure and function in living things, meaning that all biological functions occur within cells.
The third tenet states that all cells arise from pre-existing cells, which refutes the idea of spontaneous generation and highlights cell division as the source of new cells.
