NCERT Activity 6.1: Touch the leaves of Mimosa pudica and watch them fold inward — a thigmonastic response driven by electrical signals and water loss from pulvinus cells.
NCERT Activity 6.2: Place a plant near light and watch the stem bend toward it (positive phototropism) while roots grow away — driven by auxin redistribution.
NCERT Activity 6.3: Place a seedling horizontally and watch the root bend downward (+geotropism) while the stem bends upward (−geotropism) — driven by opposite auxin effects.
NCERT Activity 6.4: Watch roots grow toward a buried water source (positive hydrotropism) — even overriding gravity because water is more critical for survival.
NCERT Activity 6.5: Tap below the kneecap and trace the reflex arc — stimulus → sensory neuron → spinal cord → motor neuron → muscle. See why reflexes bypass the brain for speed.
