a nastic response. if it helps its the only coice that has response on it.
A responsive movement of a plant that is not dependent on the direction of the stimulus is called a non-directional or non-tropic movement. Examples of non-directional movements in plants include thigmonasty (response to touch), nastic movements (response to changes in environmental conditions), and nyctinasty (response to changes in light).
Nastic response occur in a part of a plant that grows towards a non-directional stimulus while Tropic response occur in a part of a plant that grows towards or away from a directional stimulus.
Phototropism is the growth response of plants to light, where they bend towards the light source. This directional growth allows plants to optimize their exposure to sunlight for photosynthesis. Phototropism is mainly controlled by the plant hormone auxin.
Nastic movements are non-directional responses to external stimuli, triggered by changes in environmental factors like temperature or humidity. These movements are not correlated with the direction of the stimulus. Tropic responses, on the other hand, involve directional growth or movement of an organism in response to a stimulus, such as phototropism (response to light) or gravitropism (response to gravity).
The root grows downward due to gravitropism, a plant's response to gravity, while the shoot grows upward towards light through phototropism, a plant's response to light. These directional growth patterns enable the root to anchor the plant and absorb water and nutrients from the soil, while the shoot reaches for sunlight to undergo photosynthesis for energy production.
It is the directional response of a plant organ to physical contact with a solid object.

Phototropism, where the plant "turns" to arrange its leaves for better exposure to light. This process is regulated by growth regulators in the plant. Photo = light Tropism from the Greek "trope" or turning. See picture
Nastic response occur in a part of a plant that grows towards a non-directional stimulus while Tropic response occur in a part of a plant that grows towards or away from a directional stimulus.
Directional growth in which the direction of growth is determined by the direction of the light source. In other words, it is the growth and response to a light stimuli.
Tropism is the directional growth response of a plant in response to a stimulus. Two examples of tropism are phototropism, where plants grow towards light, and gravitropism, where plants grow in response to gravity.
Phototropism is the growth response of plants to light, where they bend towards the light source. This directional growth allows plants to optimize their exposure to sunlight for photosynthesis. Phototropism is mainly controlled by the plant hormone auxin.
Auxins play a crucial role in phototropism, the plant's growth response to light. They promote elongation of cells on the shaded side of the plant, causing it to bend towards the light source. Auxins help to redistribute growth hormones, leading to asymmetric growth and the plant's directional growth towards light.
when the fixed part of a stationary plant moves in response to a stimulus the reaction is known as tropic movement.or the movement in which fixed part of stationary plant moves in response to a stimulus is known as tropic movement or tropism.
Directional stimuli are environmental stimuli, particularly light and sound, that the direction of which it comes and the direction of the response to the stimulus are of upmost importance. Non-directional stimuli are those where receptors do not detect the direction from which they come. Chemical stimuli are usually not directional.
A stimulus is any change in the environment that elicits a response from an organism. Tropism, on the other hand, is a directional growth response of a plant to a stimulus, such as light or gravity. In other words, tropism is a specific type of response exhibited by plants in reaction to environmental stimuli.
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.
