What are examples of response?

What are examples of response?

The definition of response is a reaction after something is done. An example of response is how someone reacts to an ink blot on a card. A reaction, as that of an organism or a mechanism, to a specific stimulus.

What is an example of an external stimulus?

External stimuli are changes to conditions outside of the body, or in general, information from outside the body that our senses detect. For example, our bodies respond to changes in light and temperature and to sources of danger.

How do plants respond to internal and external changes?

Plants may respond to the following external stimuli: Light: Plants rely on photosynthesis to convert light energy into chemical energy. Touch: Plants respond to touch through thigmotropism. Plants exhibit thigmotropism when they change their growth to bend around an object or grow up a wall or tree.

What is a response to an external stimulus?

Term: response to external stimulus
Synonyms: response to environmental stimulus
Definition: Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an external stimulus.

Is the ability to respond to a stimulus quickly?

The ability of an organism or organ to respond to external stimuli is called sensitivity.

What is the difference between internal and external response?

An external stimulus is a stimulus that comes from outside an organism and causes a reaction. An internal stimulus is a stimulus that comes from inside an organism.

Do plants respond to stimuli?

Summary. Like all organisms, plants detect and respond to stimuli in their environment. Their main response is to change how they grow. Plant responses are controlled by hormones.

What are Phytohormones give an example?

Plant hormones are called as phytohormones. These are the organic substances which are produced in the plants These hormones are otherwise called as growth regulators. Different growth regulators present in the plant are Auxins, Gibberillins, Cytokinins, Ethylene and Abscisic acid.

What is the best explanation of Thigmotropism?

Also referred to as haptotropism, thigmotropism is the movement or change in orientation of a plant’s growth as a reaction to touch. The orienting factor is generally a hard surface that can change the direction of the plant’s growth or the growth of one of its organs.

What are 2 stimuli that roots respond to?

A tropism is a growth toward or away from a stimulus. Common stimuli that influence plant growth include light, gravity, water, and touch.

What are the 5 Tropisms and the plant’s response to each?

Plants are like humans and animals, at least in the sense that they constantly adapt to their environment to preserve their well-being. Phototropism, thigmotropism, gravitropism, hydrotropism, and thermotropism are common tropic responses in plants.

What are the three types of tropism?

Tropisms are growth toward or away from a stimulus. Types of tropisms include gravitropism (gravity), phototropism (light), and thigmotropism (touch).

What causes a phototropic response in plants?

influence of plant hormones The phototropic response occurs because greater quantities of auxin are distributed to the side away from the light than to the side toward it, causing the shaded side to elongate more strongly and thus curve the stem…

What hormone is responsible for Hydrotropism?

Plant hormones and hydrotropism. Auxin plays a central role in several tropisms and might be involved in hydrotropism too.

What is the importance of Photoperiodism in plants?

Importance of photoperiodism : (a) Photoperiodism determines the Season in which a j particular plant shall come to flower . (b) Knowledge of photoperiodic effect is useful in keeping some plants in vegetative growth, to obtain higher yield of tubers, rhizomes etc., or keep the plant in reproductive stage.

What is an example of Gravitropism?

The growth response of a cell or an organism to gravitational field is called gravitropism. Gravitropism is a feature exhibited by many organisms, such as most plants and fungi. For instance, the roots of the plants grow towards the gravitational field whereas the stem grows away from the gravitational field.

What is Thigmotropism give example?

An example of thigmotropism is the coiling movement of tendrils in the direction of an object that it touches. On the other hand, the folding movement of the Mimosa pudica leaflets, can be considered as an example of thigmonastism.

What are main functions of leaves?

The main function of a leaf is to produce food for the plant by photosynthesis.

What is Geotropism with example?

The definition of geotropism is the growth of a plant or immovable animal in response to the force of gravity. An example of geotropism is the roots of a plant growing down into the ground. Roots display positive geotropism when they grow downwards, while shoots display negative geotropism when they grow upwards.

What are examples of response?

What are examples of response?

Response: how the organism reacts to a stimulus and results in a change in behavior. (It is a fancy way of saying “effect”.) Example: Getting a drink when you are thirsty.

What is difference between stimuli and response?

The main difference between stimulus and response is that a stimulus is an event or condition which initiates a response whereas response is the organism’s reaction to a stimulus.

What happens between stimulus and response?

In that space is our power to choose our response. In our response lies our growth and our freedom.”

What brain area is most important for forming stimulus response associations?

prefrontal cortex

How do we learn from association?

refers to learning that occurs when a neutral stimulus (e.g., a tone) becomes associated with a stimulus (e.g., food) that naturally produces a behavior. After the association is learned, the previously neutral stimulus is sufficient to produce the behavior.

How do we learn from association between stimuli and response?

Associative learning modifies the behavior via relating one stimulus with another, or relating a stimulus with a particular behavior. In classical conditioning, a person pairs two stimuli, and therefore reflex response is modified.

Is Association to a stimulus contributes to learning?

Classical conditioning refers to learning that occurs when a neutral stimulus (e.g., a tone) becomes associated with a stimulus (e.g., food) that naturally produces a behaviour. After the association is learned, the previously neutral stimulus is sufficient to produce the behaviour.

What is the relationship between stimulus intensity and tissue response?

As the intensity (voltage) of the stimulus is increased above the threshold, more and more fibers are stimulated and the response becomes greater and greater. Eventually, however, stimulus intensity (voltage) is reached beyond which the response is constant.

What is Supramaximal response?

Supramaximal stimulation is stimulation having intensity (voltage or current) significantly above that required to activate all the muscle fibers. Once attached to the transducer the muscle is stimulated with a single electrical pulse to produce a twitch response.

What is the difference between stimulus intensity and stimulus frequency?

What is the difference b/w stimulus intensity & stimulus frequency? Stimulus intensity describes the amount of force generated to administer the stimulus. The more force that is used will increase the stimulus intensity. Stimulus frequency refers to the rate of delivered stimulus to the muscle.

What is the relationship between stimulus frequency and muscle force?

The force developed increases as the stimulus frequency increases – to a point.

Why does the muscle force increase as voltage stimulus is increased?

Increasing the stimulus voltage on isolated skeletal muscle increases the amount of active force produced by the muscle. This happens because more fibers and motorneurons are activated and leads to an increase in muscle force.

How do action potentials change in response to stimulus intensity?

When the intensity of the stimulus is increased, the size of the action potential does not become larger. Similarly, for the motor system, the greater the number of action potentials in a motor neuron, the greater the intensity of the contraction of a muscle that is innervated by that motor neuron.

What affects stimulus intensity?

In the same way the main effect of a nociceptive stimulation is that the intensity of the response is proportional to the logarithm of the concentration of the irritant (the greater the concentration the smaller the increase in the response).

Which stimulus will have no effect?

The Role of the Neutral Stimulus A good example of a neutral stimulus is a sound or a song. When it is initially presented, the neutral stimulus has no effect on behavior. As it is repeatedly paired with an unconditioned stimulus, it will begin to cause the same response as the UCS.

Is a quick and accurate response to stimulus?

A reflex, commonly known as a reflex action is the quick, instant response given by the body to an external or an internal stimulus. A reflex is basically an automatic response without any conscious thought.
