Which option gives the correct cause of a non-growth-based plant movement?
Answer and explanation
Correct answer: Change in the amount of water in cells
Non-growth-based plant movements are usually rapid and reversible because they result from changes in the water content and turgor pressure of cells, not from the production of new cells. In Mimosa, a stimulus causes water to move out of particular motor cells, making the leaf fold. Thus option A is correct. Options B and C describe growth, while option D is chemotropism, a directional growth response.
