tropism = growth
positive tropism = growing with something
negative tropism = growing against something
eg
positive phototropism - growing towards light (plant shoots/coleoptiles*)
negative phototropism - growing away from light (roots)
positive geotropism - growing according to gravity (roots)
negative geotropism - growing against gravity (shoots/coleoptiles*)
*coleoptiles = another name for shoots.
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
Positive phototropism, where the plant stem grows towards a source of light.
It occurs so that the plant will always place the broad side of it's leaves toward the Sun.
Tropism is the fact of living things turning toward or away from something. Light is an example. In sunflowers case, the sun is the best example.
No, fire is not an example of tropism. Tropism is a biological response in plants to external stimuli, such as light or gravity, leading to growth or movement. Fire, on the other hand, is a chemical reaction involving combustion that releases heat and light energy.
i have no idea lol
A positive tropism is something that bends with gravity or bends towards the light or the roots grow towards water. A negative tropism does the exact opposite.
photo tropism is the growth-response to light in a plant. stems exhibit positive photo tropism while most roots exhibit negative photo-tropism
tropism. Tropisms can result in growth toward (positive) or away from (negative) a stimulus, such as light or gravity.
well there is a type of flower to where if you touch it the leaves will turn brown and die

When a shoot grows away from gravity - as it does when it emerges from the seed underground, and there is no light.
Yes, that's correct. Tropism is the growth or turning movement of a plant in response to a stimulus such as light, gravity, or touch. Plants can exhibit positive tropism by growing towards a stimulus or negative tropism by growing away from a stimulus.
A tropism in which the roots of plant grow downward, in the direction of gravity
Tropism is a plant's movement in response to an external stimulus, such as light or gravity. It can be positive (towards the stimulus) or negative (away from the stimulus). Examples include phototropism (response to light) and gravitropism (response to gravity).
Positive phototropism, where the plant stem grows towards a source of light.
Planarians exhibit a fairly strong negative geo-tropism and would move away from light.
