Positive thigmotropism is a term used in plant Biology. Thigmotropism is a growth response to touch either towards (positive) or away from a stimulus (negative). Roots of plants typically show a negative thigmotropic response when they come in contact with an object in the soil such as a rock. The roots will curve away from the object.
Positive thigmotropism can be seen in vines. When a vine comes into contact with an object, the side of the vine that did not touch the object will grow slightly faster than the side with the contact. This causes the vine to curve towards the object and wrap around it, giving the plant added structural support.
The plant is able to perceive the touch sensation and alter its growth pattern.
There are many more examples out there ... but roots and vines are the most common. And remember: Tropisms only occur when the plant is growing.

Pictures of a thigmotropism?
Thigmotropism is the growth response of plants to contact or mechanical stimulation. Examples include vines wrapping around a support structure and tendrils coiling around objects for support. These plants exhibit thigmotropism as a way to seek structural support for growth.
What are examples of thigmotropism?
Some examples of thigmotropism include the curling of tendrils around a support structure by climbing plants, such as pea plants, and the coiling of sensitive plant leaves in response to touch or movement. Thigmotropism can also be observed in the way vines like ivy attach and climb the walls of buildings.
What force allows roots to grow in the soil?
Roots grow in soil due to a combination of factors such as geotropism (response to gravity), thigmotropism (response to touch), and chemotropism (response to chemicals). These forces help roots navigate through the soil, find nutrients, water, and anchorage, and ultimately support plant growth.
Positive and negative ions for sodium nitrate?
Sodium will be positive. Check your periodic table; all those elements on the left will always be positive ions.
What is a positive side?
This question is incomplete. A positive side could mean the positive side of a situation. A positive side could mean the side that is correct or apart of a chemical equation.
Which tropism is shown by the tendrils of climbers?
Thigmotropism - tendrils of climbers exhibit a positive thigmotropism by growing towards and wrapping around a support structure to aid in climbing and anchoring the plant.
A grapevine coiling around a fence post is an example of?
Choose yourself A. Positive gravitropism B. positive thigmotropism C. Negative phototropism D. All of the above
What is plant growth in response to touch called-?
thigmotropism
A plant that responds to touch is showing what?
A plant that responds to touch is exhibiting thigmotropism. Thigmotropism is a response where a plant changes its growth pattern in response to touch or contact with a solid object.
Ivy clings because of what?

What is growth in response to growth called?
thigmotropism
Growth of a vine around a post is an example of a gravitropism or a thigmotropism?
The growth of a vine around a post is an example of thigmotropism, which is a plant's response to touch or contact with a solid object. Gravitropism, on the other hand, is a plant's response to gravity, causing roots to grow downward and shoots to grow upward.
Pictures of a thigmotropism?
Thigmotropism is the growth response of plants to contact or mechanical stimulation. Examples include vines wrapping around a support structure and tendrils coiling around objects for support. These plants exhibit thigmotropism as a way to seek structural support for growth.
What is the tendency of a plant to grow toward a stimulus called?
The tendency of a plant to grow toward a stimulus is called positive tropism. This can be in response to light (phototropism), gravity (gravitropism), or touch (thigmotropism).
