Which option correctly analyses growth-based and non-growth-based plant responses?
Answer and explanation
Correct answer: Phototropism is growth-based, while folding of a Mimosa leaf is non-growth-based
Phototropism is a growth movement because unequal cell elongation causes a plant part to bend toward or away from light, and the change is associated with lasting growth. Mimosa folding is a rapid non-growth movement caused by reversible water and turgor changes in cells. Therefore option A is correct. Both phenomena occur in plants, and neither is controlled only through blood.
