Question

which statement is one component of the cell theory?
all living and nonliving things consist of one or more cells.
cells and living organisms are spontaneously created.
cells are the most complex unit of structure and function in living things.
a cell is the basic unit of structure and function of all organisms.

Explanation:

Cell theory has three main components: all living things are made of cells, the cell is the basic unit of structure and function in living things, and all cells come from pre - existing cells. Analyzing each option:

• Option 1: Non - living things do not consist of cells.
• Option 2: Cells and living organisms are not spontaneously created (disproven by the cell theory which states cells come from pre - existing cells).
• Option 3: Cells are the basic (not the most complex) unit of structure and function.
• Option 4: This aligns with one of the main components of cell theory.

Answer:

A cell is the basic unit of structure and function of all organisms.
