What is the difference between taxes and kinesis

Chlamydomonas a single cell green algae move towards the light from low light intensity to high intensity. This movement can reflect as positive phototaxis. In multicellular organisms, sperm movement towards the egg cell also considers as positive chemotaxis. Kinesis is designating as a non-directional response by organisms to a stimulus.

The organism cannot move towards, or away from the location of the stimulus, instead it shows random movements to move into a comfortable place.

Kinesis moves irregularly and refers to the change in the action of an organism depending on the intensity of a stimulus. Some types of stimuli generating kinesis are gas exposure, ambient temperature, etc. They also generate random movements. Kinesis is neither positive nor negative.

Instead of the organism stirring towards or away from the stimulus, the stimulus causes it to bolt in random directions.

Depending on the relief zone of each organism, the rate of kinesis can differ as fast movement shows that the organism is searching for a relief zone while slow movement indicates that the organism is already establishing its comfort zone. Kinesis is dividing into two types as orthokinesis and klinokinesis. Orthokinesis involves the requirement of stimulus to the movement of the individual. The movement of woodlice near the temperature around it.

When humidity increases, the position of the woodlice is staying stationary. Klinokinesis contains the frequency or rate of turning proportional to the intensity of the stimulus. The difference between taxis and kinesis is that the taxis have a specific type of motion that is directed; on the other hand, kinesis has random and undirected motion.

Both of them respond to stimulus and are found in living beings like animals and insects. Taxis is the biological behavioural response of a cell or an organism to an external stimulus, which may be towards or away from the source of stimulus. There are several types of taxis identified; aerotaxis, anemotaxis, barotaxis, chemotaxis, durotaxis, galvanotaxis, gravitaxis, hydrotaxis, magnetotaxis, phonotaxis, phototaxis, rheotaxis, thermotaxis, thigmotaxis, etc..

In taxis like thermotaxis, the animal would respond to the temperature stimulus, in phototaxis the animal would respond to light stimulus, in chemotaxis the animal would respond to any chemical stimulus, in thigmotaxis the animal would respond to touch or contact, and so on. There are two types of movements in taxis that are positive and negative.

Positive movement is said when the movement is towards the source of stimulus and negative is said when the movement is away from the source of stimulus.

The response is common in every animal but still, some exceptions are there. The normal animal behaviour depends on their surroundings and thus the animal brain responds differently in every situation and stimulus.

The behaviour also varies from animal to animal. There are many kinds of fish there are also positively rheotactic and we can take the example of trout in this regard. Response to touch or contact is called Thigmotaxis. If we try to talk about Paramecium in this regard, then it shows a strange behavior in terms of Thigmotaxis.

On coming in contact with these objects, Paramecium will stay very quiet. On the other hand, if we talk about another scenario where the interior of Paramecium is touching a solid object, it will exhibit strong avoiding reactions. When an organism is responding to a stimulus of light, it is exhibiting Phototaxis. Euglena is a beautiful organism and it always moves toward the source of light thus exhibits positive Phototaxis.

On the other hand, cockroaches, silverfish, slugs, and earthworms will always try to move away from the source of light and will exhibit negative Phototaxis. Paramecium and Amoeba like staying in complete darkness and they avoid sunlight, but both of these organisms respond positively to normal or weak light.

Whenever the animal will respond to the stimulus of temperature it will be called Thermotaxis. When it comes to animals then they like thriving at an optimum temperature that ranges between 20 to 25 degrees centigrade. When the temperature is optimum then the organisms show a positive response towards it. Amoeba and Paramecium show positive Thermotaxis in the temperature that ranges between 20 to 25 degrees centigrade.

On the other hand, if the temperature is higher or lower than the optimum temperature then the organisms will show negative Thermotaxis. Animals showing response to anything related to chemicals is called Chemotaxis. Most of the organisms show a negative response to chemicals. When it comes to mosquitoes or Amoeba, then these organisms are always going to show a negative response to strong solutions of alkalis, acids, or sugars.

In most of the scenarios Paramecium shows a positive response to weak acid solutions, however, its response to a strong salt solution will always be negative. When there are chemicals then the animals are likely to show negative chemotaxis more than positive. An ideal example of chemotaxis in the human body is seen during the process of information. Any injury to the tissue releases certain chemotactic factors such as chemokines.

These factors cause the white blood cells and other components of the defense system to leave the bloodstream and move towards the site of injury. This is essential to treat the infection, fight it as soon as it occurs, and limit it to the site of origin.

Another example of chemotaxis is seen during bleeding. When a blood vessel is injured and the blood begins to bleed, the injured tissue releases chemicals to attract components of the coagulation system at the site of bleeding. It helps to limit bleeding and form a blood clot immediately. The movement of an organism in response to an electric current is called Electro taxis or galvanotaxis.

In Biology taxis and Kinesis go hand in hand. All the organisms in the world exhibit different responses to different stimuli. When the response is directional it is called a Taxis movement and when the response is non-directional then it is called the Kinesis movement. A stimulus is an object in the environment that has the capability of eliciting responses from organisms. This stimulus can be. The response is the reaction of organisms to the stimulus.

Animals and plants both show responses to a stimulus in different ways. While plants are a little slower in exhibiting response animals can be faster. There is a great difference between these two movements. In the Taxis movement, organisms either move towards the stimulus or away from it. In Taxis, movement is always directional.

It is not rapid, haphazard, or random. Fire is a form of light energy and due to its intensity, the movement of the organism is going to be haphazard and rapid.
