How are folding of Mimosa leaves on touch and coiling of a tendril around a support different?
Answer and explanation
Correct answer: Mimosa involves rapid water change, whereas a tendril involves growth-based inequality
Mimosa leaf folding is a rapid, non-growth movement caused mainly by changes in water content and turgor pressure in specialized cells. Tendril coiling is a slower growth movement in which touch produces unequal elongation on opposite sides. Thus option A correctly distinguishes the mechanisms. Neither response requires a brain, blood, insulin or a spinal cord because these are not plant nervous-control structures.
