which of these involves the cell theory?
every new cell comes from the division of a pre - existing cell.
all cells are alike.
all living things are made of cells.
all living things are made of cells, and every new cell comes from the division of a pre - existing cell.
every new cell comes from the division of a pre - existing cell, and all cells are alike.

Explanation:

Cell theory states three key points: all living organisms are composed of one or more cells; the cell is the basic unit of structure and organization in organisms; and all cells arise from pre-existing cells. The option combines the first and third core tenets, while others are incomplete or incorrect (e.g., "all cells are alike" is false as cells vary in structure/function).

Answer:

All living things are made of cells, and every new cell comes from the division of a pre-existing cell.
