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.

What is an example of internal stimulus and external stimulus in plants?
An example of an internal stimulus in plants is the production of hormones like auxins in response to light, which causes phototropism, or the bending of a plant towards light. An external stimulus example is gravitropism, where roots grow downward in response to gravity. Both stimuli help plants adapt to their environment and optimize their growth and survival.
What is a stimulus give an example of an external stimulus and an internal stimulus in plants?
A stimulus is any change in the environment that prompts a response from an organism. An example of an external stimulus in plants is light, which influences processes like phototropism, where plants grow towards a light source. An internal stimulus could be the concentration of water within the plant, which can trigger responses such as closing stomata to reduce water loss during drought conditions.
What is the name for a change in the environment that causes an organism to change its activity What is an example of a response What is an example of an internal stimulus?
stimulus,an example a insect touching the hair like figures on a venus fly trap
Is A plant wilting when the soil dries out an internal stimulus?
No, a plant wilting due to dry soil is not an internal stimulus; it is a response to an external environmental factor. The plant's wilting is a reaction to the lack of water, which affects its turgor pressure and overall health. This response helps the plant conserve water and minimize stress until conditions improve.
What is the plant's response to the stimulus?
Tropism is the response plants have towards external stimulus.
What is a plant response to a stimulus called?
Tropism is the response plants have towards external stimulus.
Is geotropism internal or external stimulus?
Geotropism is an external stimulus. It refers to the growth response of plants to gravity, where roots grow downward (positive geotropism) and stems grow upward (negative geotropism). This response is influenced by the gravitational pull, making it an external factor affecting plant growth and orientation.
What a plant or animal does after receiving a stimulus is an example of a?
What a plant or animal does after receiving a stimulus is an example of a reaction. If the stimulus is unexpected, the reaction is an involuntary one.
Is light an external or internal stimulus for a plant?
Light is considered an external stimulus for a plant. It influences various growth and developmental processes, such as photosynthesis, phototropism, and flowering. Plants respond to light through mechanisms like photoreceptors, which allow them to adapt to their environment. These responses are crucial for maximizing energy capture and optimizing growth.
Which of the following is an example of a plant responding to an external stimulus?
The closing of a Venus flytrap in response to the touch of an insect is an example of a plant responding to an external stimulus. The plant detects the movement of the insect triggering the trap to snap shut, capturing the prey for nutrition.
Is a leaf external or internal?
Leaf is an external organ of the plant
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'.
