Which of these external stimuli produces growth of the plant toward light?
The stimulus that produces growth of the plant toward light is called phototropism. It is caused by the presence of blue light, specifically light in the 440-470nm wavelength range, which is detected by the plant's photoreceptor molecule called phototropin. This photoreceptor triggers a signaling pathway that stimulates cell elongation on the shaded side of the plant, resulting in growth towards the light source.
What is the word for a Plant that grows towards the light?
phototropic (details from another answer) movement of or growth of plant in response to external stimulus. e.g. growth of root towards gravity - geotropism growth of shoot towards the light - phototropism hydrotropism is exhibited by lengthening of roots towards water source and finally, thigmotropism is growth towards solid objects -support by climbers
Which response is result of geotropism?
Growth of plants toward the light is called phototropism. Growth of plants in response to gravity is called geotropism or gravitropism.
Which type of response is the growth of a flower toward light?
I think you're talking about phototropism.
Is tropism an adaptation of movement a plant makes to situate itself toward light?
True
What is growth of a plant movement toward light called?
phototropism.
Plants lean toward the light because of plant hormones called what?
A growth hormone called auxin.
What is a plant's movement away from or toward a stimulus?
Tropism is the movement of a plant away from or toward a stimulus. The most easily found example of tropism is a plant's response to light. Plants tend to grow toward the light. This tendency is called 'phototropism'.
A plant seedling grows toward the window and its roots reach into the soil what type of movement does the seedling show?
These growth responses are called tropisms. Growing towards the light is called phototropism, and towards the source of gravity is geotropism.
The responses of plants to external stimuli are called?
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.

Which response is result of geotropism?
Growth of plants toward the light is called phototropism. Growth of plants in response to gravity is called geotropism or gravitropism.
What word describes plant growth toward light?
positive phototropism
What meant by phototropic movement?
When concluded that auxin accumulated on the side of the plant away from the light. When auxin flowed in this direction, the cells of the apical meristem elongated on that side and caused the plant to bend toward the light as growth continued.
What is an example of a non growth plant movement?
An example of a non-growth plant movement includes the tendency of a plant to bend in the direction of light.
A plant sits on a window sill over time the stems of the plant curve toward the light coming in the window this process is called?
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.
