Contrast the speed of movement in the sensitive plant with that of sunflowers in response to day or night.

The sensitive plant (Mimosa pudica) exhibits rapid turgor movements, responding within seconds to touch by folding its leaflets. This quick response is a defensive mechanism against potential threats. In contrast, sunflowers (Helianthus annuus) demonstrate slower movements associated with phototropism. Sunflowers exhibit a diurnal heliotropic movement, tracking the sun’s position across the sky during the day. While not as rapid as the sensitive plant’s response to touch, the gradual reorientation of sunflower heads over the course of the day showcases the adaptability of plants in optimizing light exposure for photosynthesis.
