Response. The stimulus is the light.
1)Touch me not plant folding its leaves when touched. 2)Plant growing towards light when kept in a dark room with a small hole for light. 3)
Tropism is the movement of a plant away from or toward a stimulus. The most easily found example of tropism is a plant's response to light. Plants tend to grow toward the light. This tendency is called 'phototropism'.
A tropism is a growth response whose direction is determined by the direction of the stimulus. Growth towards the stimulus is called a positive tropism. Growth away from the stimulus is called a negative tropism. The response to light is called phototropism. Shoots are positively phototropic, roots are negatively phototropic. The response to gravity is called gravitropism (or sometimes geotropism). Shoots are negatively gravitropic and roots are positively gravitropic. http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/T/Tropisms.html
Towards. As in, phototropism. The tendency of plants to grow towards light.
Tropisms is the response to an external stimulus in a specific direction.

phototropic (details from another answer) movement of or growth of plant in response to external stimulus. e.g. growth of root towards gravity - geotropism growth of shoot towards the light - phototropism hydrotropism is exhibited by lengthening of roots towards water source and finally, thigmotropism is growth towards solid objects -support by climbers
Movement in response to light is called phototaxis, and in response to chemicals is chemotaxis. More specifically, movement towards a stimulus is positive and away from is negative. For example, positive chemotaxis is movement of a cell towards nutrients.
Okay, well there is tropism and stimulus. The stimulus can be gravity, light, and touch. So it depends... If there is a window above the plant and it is reaching upwards towards it... then it would be light, and the plant's response would be reaching upward towards it.
The reason cress seeds bent towards the light is because they are positively photropic.
umm im pretty sure its responce :) hop i helped A plant growing toward light is an example of positive phototropism.
)Movement or activity of an organism in response to a stimulus such as light.
A plant does not grow upwards. A tropism is the growth of a plant in response to a stimulus. This means a plant does not grow upwards, it grows towards a stimulus which in most cases is light. Try it out, put a plant in a dark closet with a light on one side and watch the plant grow towards the light. The results should be clear after a number of days. The plant's response to light is known as phototropism. Hope I helped :)

Stimulus?
A tropism is a growth response whose direction is determined by the direction of the stimulus. Growth towards the stimulus is called a positive tropism.
