Define tropism and give two examples?

Tropism is the directional growth response of a plant in response to a stimulus. Two examples of tropism are phototropism, where plants grow towards light, and gravitropism, where plants grow in response to gravity.


What are the four tropisms?

Tropism is a biological phenomenon where an organism responds to the stimulus brought by the environmental factors. Some examples include: chemotropism, heliotropism, phototropism, thermotropism and electrotropism.


What is a plant's movement away from or toward a 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'.


What is the tropism plant called that reacts towrad the stimulus?

The type of plant tropism that involves growth toward a stimulus is called "positive tropism." An example of this is phototropism, where plants bend toward light sources to maximize photosynthesis. This response is driven by differential growth rates on the sides of the plant, allowing it to optimize its exposure to sunlight. Other examples include gravitropism, where roots grow downward in response to gravity.


What are 5 types of tropism?

The 5 types of tropism are geotropism, phototropsim, hydrotropism, chemotropsim, and thingmotropism.


Can there be tropism in animals?

Its possible, but only certain forms of tropism may affect certain animals.


Define the four tropisms?

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.


What tropism is venus fly trap belong to?

The Venus Fly Trap does not belong to any Tropism. That is because it's reaction is not caused by light, gravity, touching, or the presence of water. Therefore, it is not Tropism.


What is a tropism that is towards the stimulus called?

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


How does light brings about tropic movement in the stem and root of a flowering plant?

photo tropism is the growth-response to light in a plant. stems exhibit positive photo tropism while most roots exhibit negative photo-tropism


How does tropism benefit plants?

This is by photosynthesis


Is giraffe an example for tropism?

yes
