Question #46711
The Question
Read the following statements correlating the principles of Cell Theory, cellular boundaries, and plant development. Which of the following statements is INCORRECT?
Options
- A.
Schwann hypothesized that the bodies of animals and plants are composed of cells and products of cells, identifying the cell wall as a unique character of plant cells.
- B.
Mycoplasma completely lacks a cell wall but remains the smallest living cell, conforming to the functional definition of the cell theory.
- C.
The original cell theory formulated by Schleiden and Schwann successfully established the cell as the basic unit of life but failed to explain how new meristematic cells are formed.
- D.
The totipotency of a plant cell is strictly dependent on the structural integrity of its cellulosic cell wall, as isolated wall-less protoplasts cannot regenerate into a whole plant.

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Students often conflate the structural boundary of a plant cell (cell wall) with its functional genetic capacity (totipotency).
The trap leverages the misconception that removing the cell wall (creating a protoplast) destroys the cell's ability to act as the basic unit of growth and development.
It also tests the exact historical nuances of Schleiden and Schwann's contributions versus Virchow's.
