well ..thats a good question.. i studied that for a while and if i remember , it is called POSITIVE TROPISM.. but if it grows away from the stimulus its NEGATIVE TROPISM. Nice question.. alot of people ask that.. but they really dont pay attention because it in the question! :)
hope this helps!! :) :P
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.
It is called geotropism.
A tropism is an environmental stimulus that affects a plants behavior. If you observe plants growing on a window cill or something similar, you will see they lean towards the window in an attempt to get more sun. Plants grow towards light in an attempt to get more sun. This is called 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 general term for this behavior is tropism. It can take a variety of forms, including phototropism (when the stimulus is light) and chemotropism (when the stimulus is a particular chemical).
Tropism is the response plants have towards external stimulus.
Tropism is the response plants have towards external stimulus.
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'.
Tropism
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.
Tropism

Tropism: An involuntary orienting response; positive or negative reaction to a stimulus source. An example would be the involuntary movement of a plant towards sunlight.
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.
