The stimulus for a plant growing toward light is phototropism, which is the plant's growth response to light direction. In this process, cells on the side of the plant that is away from the light elongate more than those on the side facing the light, causing the plant to bend toward the light source. This response is primarily regulated by the plant hormone auxin, which redistributes in response to light, promoting growth on the shaded side. This adaptation helps maximize light absorption for photosynthesis.

When a plant grows toward light is the suns light the stimulus?

Yes, the sun's light is the stimulus that causes a plant to grow towards it, a process known as phototropism. The plant's cells detect the direction of the light source and auxin hormones help to promote growth on the shaded side, causing the plant to bend towards the sunlight.


What is the tendency of a plant to grow toward a stimulus called?

The tendency of a plant to grow toward a stimulus is called positive tropism. This can be in response to light (phototropism), gravity (gravitropism), or touch (thigmotropism).


Is tropism an adaptation of movement a plant makes to situate itself toward light?

Yes, tropism is a plant's growth response to a stimulus like light. Phototropism, in particular, is a plant's movement toward or away from light to maximize photosynthesis. This adaptation helps plants optimize their exposure to sunlight for optimal growth and survival.


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

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'.

Is a plant growing towards light a response or stimulus?

It is a response called phototropism, where the plant grows towards light as a result of the stimulus of light perception.

Plant growing toward light is called?

Phototropism


A plant's growth response toward or away from a stimulus is called a?

tropism. Tropisms can result in growth toward (positive) or away from (negative) a stimulus, such as light or gravity.


Is tropism the movement of a plant towards or away from a stimulus?

Yes, that's correct. Tropism is the growth or turning movement of a plant in response to a stimulus such as light, gravity, or touch. Plants can exhibit positive tropism by growing towards a stimulus or negative tropism by growing away from a stimulus.


A plant growing toward a light is an example of?

umm im pretty sure its responce :) hop i helped A plant growing toward light is an example of positive phototropism.


What is the difference between taxis and tropism?

Tropism: is the growth response of a plant that results from certain stimuli. Tropism can be positive, in which case the plant will bend toward the stimulus, or negative, in which case the plant will bend away from stimulus. Taxis: Taxis in animals is the responsive movement of going toward or away from an external stimulus.


Is tropism an adaptation of movement a plant makes to situate itself toward light?

What is stimulus with examples?

A stimulus is a DETECTECTABLE change in the environment. e.g. light is a stimulus to an animal or plant if it can detect the light with a sensing eye or chemical


What is one example of an external and internal stimulus of a plant?

An example of an external stimulus for a plant is light, which influences growth direction through phototropism, causing plants to bend toward the light source. An internal stimulus could be the plant's hormonal response to stress, such as the production of abscisic acid in response to drought, which triggers stomatal closure to conserve water. Both types of stimuli play crucial roles in a plant's survival and adaptation.
