Living cells come only from other living cells.
B
Cells can only be seen with a copmound light telescope.
C
Cells are the basic units of structure and function in living things.
D

Explanation: 

Detailed explanation-1: -The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory.

Detailed explanation-2: -Cell theory has 3 basic points: All living things are made of one or more cells. The cell is the smallest living thing that can perform all the functions of life. All cells must come from pre-existing cells through cellular division.

Detailed explanation-3: -A cell is the smallest unit that is typically considered alive and is a fundamental unit of life. All living organisms are composed of cells, from just one (unicellular) to many trillions (multicellular). Cell biology is the study of cells, their physiology, structure, and life cycle.

Detailed explanation-4: -The cell theory states that all biological organisms are composed of cells; cells are the unit of life and all life come from preexisting life. The cell theory is so established today that it forms one of the unifying principles of biology.

Detailed explanation-5: -Final answer: The statement which is true for cells is a single cell can perform all the functions in a unicellular organism.
