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.
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.
What are ways that plants respond to internal and external environment?
by the sun
What does internal stimuli mean in plants?
Stimuli itself is of two types - external stimuli and internal stimuli. External stimuli refers to touch, pressure, heat etc. Internal stimuli refers to the stimuli produced by body components - like hormones etc.
Is sunlight a stimulus?
Sunlight can be considered a stimulus because it is a source of energy that triggers responses in living organisms. For example, sunlight can stimulate plants to photosynthesize and grow, while in humans, exposure to sunlight can trigger the production of vitamin D in the skin.

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.
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.
Is light an external or internal stimulus for a plant?

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.

Why are sponges classified as animals than plants?
due to their internal and external structures
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'.
What is nastic response?
Nastic responses are non-directional movements of plants in response to stimuli, such as light, touch, or temperature, that do not involve growth towards or away from the stimulus. These movements occur quickly and are often reversible, such as the closing of a Venus flytrap upon prey contact or the opening and closing of flower petals. Unlike tropic responses, which are directional, nastic movements are influenced by internal factors rather than the direction of the external stimulus.
