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.
well there is a type of flower to where if you touch it the leaves will turn brown and die
Advantage
it is of tropism shape
i have no idea lol

Negative tropism refers to the movement or growth of a plant away from a particular stimulus, such as light or gravity. This differs from positive tropism, where the plant moves towards the stimulus. An example of negative tropism is the roots growing away from light.
Positive phototropism, where the plant stem grows towards a source of light.
photo tropism is the growth-response to light in a plant. stems exhibit positive photo tropism while most roots exhibit negative photo-tropism

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
When a shoot grows away from gravity - as it does when it emerges from the seed underground, and there is no light.
Tropisms are caused by directional growth responses of plants to external stimuli like light, gravity, or touch. These responses are controlled by plant hormones, particularly auxins, which regulate cell elongation and growth in response to the specific stimulus. The differential distribution of hormones on one side of the plant compared to the other causes the plant to bend or grow in a particular direction.
Plants respond to growth signals like light, water, and nutrients. These signals trigger processes like photosynthesis, cell division, and elongation to help the plant grow, develop, and adapt to its environment. Hormones such as auxin and gibberellins play crucial roles in regulating these growth responses.
Phototropism is the response of plants to light, gravitropism is the response to gravity, thigmotropism is the response to touch, and chemotropism is the response to chemical stimuli. Each tropism helps plants adapt to their environment and grow towards essential resources.
