Movement in response to light is called phototaxis, and in response to chemicals is chemotaxis. More specifically, movement towards a stimulus is positive and away from is negative. For example, positive chemotaxis is movement of a cell towards nutrients.
Movement in multicellular organisms is typically controlled by muscles, which contract and relax in response to nerve signals. This coordinated activity allows organisms to perform functions such as walking, running, and breathing. Hormones and chemical signals also play a role in regulating movement in response to various stimuli.
Chemotropism : The movement of plant parts in response to chemical stimulus is called chemotropism. example- formation of pollen tube by pollen grains in order to transfer male gamete to the ovary. Hydrotropism : The movement of plant parts in response to water is called hydrotropism. example- movement of roots in search of water.
No, fire is not an example of tropism. Tropism is a biological response in plants to external stimuli, such as light or gravity, leading to growth or movement. Fire, on the other hand, is a chemical reaction involving combustion that releases heat and light energy.
If you mean "What is an organism's reaction to physical stimuli? it is usually withdrawal or avoidance. It depends on what type of stimuli and what type of organism. Is the organism used to this type of stimuli? Is it a new strange stimuli? The question is not specific enough to answer thoroughly nor is it grammatically correct.
Mastic movements involve reversible changes in the position of plant parts in response to external stimuli, such as the opening and closing of petals in flowers. Tropisms, on the other hand, are directional growth responses of plants towards or away from external stimuli, such as phototropism towards light or gravitropism towards gravity. Mastic movements are more direct and immediate, while tropisms involve slower, growth-oriented responses.
Tropism is defined as the movement, generally by a plant, due to outside stimuli; direction of sunlight being a primary stimulus. Chemotropism is defined as oriented growth or movement in response to a chemical stimulus.
Chemotropism is the directional growth or movement of an organism in response to chemical stimuli, guiding its movement towards or away from the source. Galvanotropism is the directional growth or movement of an organism in response to electrical stimuli. Thigmotropism is the directional growth or movement of an organism in response to physical touch or contact with a solid surface.
Phototactic stimuli are related to an organism's response to light, where they move towards or away from light sources. Chemotactic stimuli involve an organism's response to chemical signals in their environment, leading to movement towards or away from the source of the chemical. Both types of stimuli play important roles in an organism's survival and behavior.
The responses of plants to external stimuli is called Tropism.Here are some tropisms:* Chemotropism, movement or growth in response to chemicals * Geotropism (or gravitropism), movement or growth in response to gravity * Heliotropism, movement or growth in response to sunlight * Hydrotropism, movement or growth in response to water * Phototropism, movement or growth in response to lights or colors of light * Thermotropism, movement or growth in response to temperature.

Movement in multicellular organisms is typically controlled by muscles, which contract and relax in response to nerve signals. This coordinated activity allows organisms to perform functions such as walking, running, and breathing. Hormones and chemical signals also play a role in regulating movement in response to various stimuli.
Chemical stimuli are signals that are produced and detected through chemical processes. In biological systems, chemical stimuli can trigger specific responses in cells or organisms, such as signaling molecules that lead to a physiological response or behavior. Examples include pheromones that attract mates in animals or neurotransmitters that mediate communication between nerve cells.
Akinesia means loss of movement. Rigor means rigidness preventing response to stimuli - also a loss of movement.
A pulvinus is the plant part responsible for facilitating a leaf blade's movement to be oriented at right angles to the sun. It is a specialized joint or swelling found at the base of the petiole that allows for controlled leaf movement in response to environmental stimuli such as light intensity. This mechanism helps optimize light interception for photosynthesis.
Stimuli can be categorized into several types, including physical, chemical, and biological stimuli. Physical stimuli encompass environmental factors like light, sound, temperature, and pressure. Chemical stimuli involve substances that can trigger a response, such as odors or taste molecules. Biological stimuli often relate to interactions within living organisms, such as pheromones or pathogens that elicit behavioral or physiological responses.
