Want this question answered?
umm im pretty sure its responce :) hop i helped A plant growing toward light is an example of positive phototropism.

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
The stimulus that produces growth of the plant toward light is called phototropism. It is caused by the presence of blue light, specifically light in the 440-470nm wavelength range, which is detected by the plant's photoreceptor molecule called phototropin. This photoreceptor triggers a signaling pathway that stimulates cell elongation on the shaded side of the plant, resulting in growth towards the light source.
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.
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'.

Response. The stimulus is the light.
Phototropism
Tropism: is the growth response of a plant that results from certain stimuli. Tropism can be positive, in which case the plant will bend toward the stimulus, or negative, in which case the plant will bend away from stimulus. Taxis: Taxis in animals is the responsive movement of going toward or away from an external stimulus.

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
A stimulus is a DETECTECTABLE change in the environment. e.g. light is a stimulus to an animal or plant if it can detect the light with a sensing eye or chemical
One origional science project is: growing a few plants, and with each plant put the light in a different area (ie: plant one gets the growing light on top, plant two gets the light on bottom, and plant three gets the light on the side). You can determine if the plants actually grow toward the light.
