  1. Question 1

    Q1. When the leaves of Mimosa pudica are touched, they fold rapidly. This movement is an anomaly because it is caused by which mechanism?

    • A) Unequal growth
    • B) Cell division
    • C) Protein synthesis
    • D) Turgor pressure changes

    Answer: Turgor pressure changes

    Explanation: Nastic movements like those in Mimosa result from rapid turgor changes; tropic movements are tempting because they involve slower, permanent growth-related changes.
