What is the difference between phototropism geotropism and thigmotropism?
Answers
Geo- means earth, tropism is movement. Geotropism is what makes roots grow toward gravity and shoots grow away from gravity, so that plants are oriented correctly in the ground.
The response of plants or animals towards light is called phototropism.
When the response is towards the light, it is called positive phototropism.
And when the response is away from the source of light, it is called negative phototropism.
For example, we see plants bending towards sunlight. It is actually their response towards light and is called positive phototropism.
Thigmotropism is the directional response of a plant organ to touch or physical contact with a solid object. This directional response is generally caused by the induction of some pattern of differential growth. This phenomenon is clearly illustrated by the climbing tendrils of some plants, such as the sweet pea

Explanation:
Tropism refers to the movement of the organism in response to the environmental stimulus.
The plants respond to the environmental stimulus which can be-
1. Phototropism- when plants respond to the sunlight like the sunflower shows phototropism
2. Geotropism- When plants grow towards the gravity that is downwards towards the soil.
3. Thigmotropism: When the plants show the response to the touch like by the creepers.
