Question

which statement is part of the cell theory?
all cells are the same.
cells are independent structures.
all cells are produced from other cells.
cells are able to make new organisms.

Explanation:

Cell theory has three core principles: all living organisms are made of cells, cells are the basic units of life, and all cells come from pre-existing cells. The option "All cells are produced from other cells" directly aligns with the third principle. Other options are incorrect: cells vary in structure/function, are not always independent (e.g., in multicellular organisms), and single cells can only form new organisms in unicellular species (not a universal cell theory statement).

Answer:

C. All cells are produced from other cells
