It is due Nastic Movement that take place in the plants actually plants do not have any specialised nervous system like human beings have but they have hormonal system like human beings and the hormone secreted by the plants deal with the stimulus for example auxin hormone which is present at tip of the roots and the shoot of a plant senses the light and moves to the side which is away from the light shady side and due to the more amount of auxin on the Shady side the Shady side will grow longer as compared to the side which is facing the sunlight that's why the plant will bend towards the sunlight. This was the response of the plant part to the sunlight and it is also known as the photo tropic movement

By changing the amount of water they change the shape of the plant cell and hence information about touch is transferred. This movement is known as growth independent movement and this is seen in the touch-me-not plant.
