Negative gravitropic response refers to the growth movement of a plant or its parts in the opposite direction of gravitational pull. This phenomenon is often observed in the stems and shoots of plants, which grow upward, away from the soil, as a means to access sunlight for photosynthesis. This response is primarily driven by the redistribution of growth hormones, such as auxins, which promote cell elongation on the lower side of the plant, causing bending and upward growth.
What else can I help you with?
When a deviation from a normal value occurs the response is to make the deviation even greater is this a negative feedback?
No, this is not a negative feedback response. In negative feedback, the system works to counteract the deviation and return to a normal value. Instead, making the deviation greater would indicate a positive feedback mechanism, where the response amplifies the initial change rather than correcting it.
In a negative feedback system what is the response of the regulator to the inappropriate change?
It benefits from the change

Are the plants roots showing a positive or negative response?
If one root is bad that means the plant is going to die soon
a form of learning in which is a voluntary response and is strengthen or weakened by its association with positive or negative consequences is called?
incorrect
Why is gravitropic response in roots important to the survival of a seedling?
Gravitropic response in roots is important for seedling survival because it helps the roots grow downward, towards the soil. This allows the roots to anchor the seedling in the ground, access water and nutrients, and provide stability against wind and environmental stress. Overall, gravitropism ensures proper root development, which is crucial for the seedling to establish itself and grow into a healthy plant.
What are the effects of the tropisms caused by light and gravity?
A tropism is a growth response whose direction is determined by the direction of the stimulus. Growth towards the stimulus is called a positive tropism. Growth away from the stimulus is called a negative tropism. The response to light is called phototropism. Shoots are positively phototropic, roots are negatively phototropic. The response to gravity is called gravitropism (or sometimes geotropism). Shoots are negatively gravitropic and roots are positively gravitropic. http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/T/Tropisms.html

E Moctezuma, L J FeldmanDepartment of Plant and Microbial Biology, University of California at Berkeley 94720, USA. edgar@nature.berkeley.edu Gravitropic perception and response are essential for the completion of the reproductive life cycle of the peanut plant (Arachis hypogaea L.). The developing seeds are buried in the soil by a specialized organ, the gynophore, allowing the fruit to mature underground. Controversy exists about the site of graviperception in the gynophore: previous workers suggested that the intercalary meristem was the zone where gravity was perceived. Taking the starch statolith hypothesis for graviperception as a framework, we explored the possibility that the starch-grain filled plastids (amyloplasts) in the starch sheath of the gynophore may be acting as gravisensors. We show that these amyloplasts sediment readily with respect to the gravity vector within 30 min of reorientation, and before there is a measurable gravitropic response. Gynophore explants were incubated with gibberellic acid and kinetin, in darkness, to remove starch from the amyloplasts. Destarching the gynophores did not inhibit overall growth of the organ, but reduced the gravitropic response curvature by 82% compared to water-treated controls. In addition, gynophores placed on a rotating clinostat (without hormone treatment) also showed a reduced gravitropic response. In conclusion, the evidence presented in this work strongly suggests that the amyloplasts of the starch sheath are responsible for gravitropic perception in the peanut gynophore. A model for graviperception in the gynophore is presented.
What is the difference between a positive and negative response in biology?
A positive response is when a response happens to a stimuli, and this response causes more of the stimuli to happen. A negative response is when a response happens because of a stimuli, and the response stops the continuation of the stimuli.
What is a negative response two letter word?
no
What does negative response in superposition theorem implies?
work
What is a horses negative response?
putting its ears back
What is the difference between feedback negative feedback a negative feedback response a negative feedback mechanism and a negative feed back loop?
in negative feedback. when an enzyme (negative feed back mechanism) produces too much of a molecule or substance that substance binds to the enzymes allosteric site to hault production of that substance (negative feedback response). and the whole process is the negative feedback loop.
What are some examples of negative geotropism?
A few examples of negative geotropism in plants include roots growing upwards in response to gravity (negative gravitropism), stems bending away from the ground to grow upwards (negative phototropism), and leaves folding upwards in response to touch or vibration (negative thigmotropism).
What is sementical and structural featuresof negative sentences?
structural negatives are sentences which gives negative sense. but when a negative response "no" appeares in front of the negative sentence, it is said to be a negative sentence.
Is Just Peachy a negative response?
Yes, it being sarcastic
Removing something that leads to a DECREASE in a response is what?
Negative reinforcement
