Question

Turgor movements are due to

• A. Reversible changes in cell volume due to changes in turgidity of cells
• B. Reversible changes in cell volume due to simple cell contraction and expansion
• C. Irreversible changes in cell volume due to maintenance of turgidity of cell
• D. Irreversible changes in cell volume due to cell elongation

Answer 1

The correct option is A Reversible changes in cell volume due to changes in turgidity of cells

Turgor movement is a reversible change in position of a plant part due to a change in turgidity of cells. It is mostly caused by contact. During turgor movement, there is change in internal water pressures of cell which in turn changes the cell volume.

Thus, the correct answer is option A.
