Tropism is the response plants have towards external stimulus.
It is a response called phototropism, where the plant grows towards light as a result of the stimulus of light perception.
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'.

The answer is the organism from the plant to the sunlight
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).
A stimulus which naturally elicits a response is called an unconditioned stimulus. This type of stimulus triggers a reflexive or innate response without prior learning.
Random movement in response to a stimulus is called kinesis. Kinesis is a non-directional response where the organism changes its rate of movement in response to a stimulus, but not the direction.
The change is actually a stimulus and when the organism reacts to the stimulus, it becomes a response. Overall, The answer is a stimulus.
Stimulus.
An organism's response to a stimulus is called a reaction or a behavior. This can include actions such as moving away from danger, seeking food, or displaying a mating behavior in response to a specific stimulus.
tropism. Tropisms can result in growth toward (positive) or away from (negative) a stimulus, such as light or gravity.
An organisms reaction to a stimulus is called RESPONSE.
