An oriented movement in response to light or chemical stimuli?
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.
How do auxins cause cells to grow?
auxin
What is movement in response to light?
Ido
What is the name of the reaction?
response to water: hydrotropism, response to light: phototropism, response to chemicals: chemotropism, response to gravity: geotropism, response to touch: thigmatropism
What are examples of heliotropism?
Hydrotropism is observed when specific plants that exhibit it grow in response to water, similar to Gravitropism, growth dependent on gravity, and phototropism, growth dependent on light. A common example of hydrotropism is found in tomato roots, as they grow specifically towards water.
Is a type of plant hormone that causes plant stems and leaves to exhibit positive responses to light?
Yes
How does light brings about tropic movement in the stem and root of a flowering plant?
photo tropism is the growth-response to light in a plant. stems exhibit positive photo tropism while most roots exhibit negative photo-tropism
How light brings about tropic movement in the stem and root of a flowering plant?
photo tropism is the growth-response to light in a plant. stems exhibit positive photo tropism while most roots exhibit negative photo-tropism
Do planaria exhibit a positive or negative phototaxis to light?
negative
An oriented movement in response to light or chemical stimuli?
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.
Plant organs and the response to stimuli?
It responses the light known as positive phototropism which means the stem grows towards the light
Is phototropism a plant's response to light?
Yes, phtotropism is a plant's response to light. Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism.
What process causes the plants stem to bend toward the light?
This is due to tropic movement(tropism) in plants in which the fixed part of a plant(such as stem) moves in response to a stimulus.If the stimulus is light(as you have asked) then it is termed as Phototropism.And further more stem shows positive phototropism.
How do auxins cause cells to grow?
auxin
What causes fluorescence in diamond?
About 30% of all gem-quality diamonds exhibit florescence, which is the gem's response to the longer UV waves in light. Florescence is caused by '. . . submicroscopic substitutions and/or shifts in the diamond structure. . . ' according to the Gemological Institute of America.
What is phototaxis?
It is the movement of organism or cell in response to light whether in the direction of light( positive phototaxis) or in the opposite direction ( negative phototaxis). the positive phototaxis is usually occurs in roots of plants whereas the negative photataxis occurs in remaining or outer part of plant in order to get light for photosynthesis.
What do you call the movement of shoot towards light?
Phototropism is a plant's growth response to a light source, determining which direction it grows in. Positive Phototropism is the tendency for a plant to grow towards the light; Negative Phototropism is when it grows away from the light.
