According to the classical cell theory, which statement best describes cells?
A
Cells are the basic unit of structure and function in all living organisms.
B
Cells arise spontaneously from nonliving matter under the right conditions.
C
New cells are formed primarily by assembly of organelles rather than division of preexisting cells.
D
Only animals and plants are composed of cells; fungi and bacteria are not.
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 preexisting cells.
Evaluate each statement in the problem against these tenets to determine which aligns correctly with the classical cell theory.
Identify that the statement 'Cells are the basic unit of structure and function in all living organisms' directly corresponds to the second tenet of the cell theory.
Recognize that the other statements contradict the cell theory: cells do not arise spontaneously from nonliving matter, new cells form by division of existing cells, and all living organisms including fungi and bacteria are composed of cells.
Conclude that the correct description of cells according to classical cell theory is that they are the basic unit of structure and function in all living organisms.
