Animals move in search of food, shelter and for reproduction. Do plants show such movement? Have you observed the leaves of Mimosa pudica (touch-me-not plant) closes on touching, whereas Helianthus annuus (sunflower) follows the path of the sun from dawn to dusk, (from east to west). These movements are triggered by an external stimuli. Unlike animals, plants do not move on their own from one place to another, but can move their body parts for getting sunlight, water and nutrients. They are sensitive to external factors like light, gravity, temperature etc. In this lesson, we will study about various movements in plants, photosynthesis and transpiration
