Question

which statement best describes the current understanding of the cell theory? f the theory applies only to single-celled organisms, such as bacteria. g cells are too small to be seen in real time, so the theory continues to be speculation. h cells are found only in larger, more complex organisms and not in simple organisms. i the cell is the basic unit of life in all organisms, no matter the size or complexity.

Explanation:

• Option F is incorrect because cell theory applies to all organisms, including multi - celled ones.
• Option G is incorrect as cell theory is a well - established scientific theory, not speculation, and cells can be observed with microscopes.
• Option H is incorrect since simple organisms (like bacteria) also have cells.
• Option I correctly states the cell theory: the cell is the basic unit of life in all organisms, regardless of their size or complexity.

Answer:

I. The cell is the basic unit of life in all organisms, no matter the size or complexity.
