Final answer:
A plant's stem leaning towards the light when placed in a window is an example of a living thing responding to stimuli, specifically through phototropism, which is driven by plant hormones and is part of how plants detect and respond to their environment.
Step-by-step explanation:
If you put a plant in your window, the stem leaning in the direction of the sun is an example of the characteristic of life that living things respond to stimuli.
This is known as phototropism, which is a specific type of stimulus-response where a plant grows towards or away from light.
This response to the stimulus of light is essential for the process of photosynthesis, which is how plants convert light energy into chemical energy.
This phototropic response demonstrates that plants, like all living things, can detect changes in their environment and react to them.
To produce a response to the stimulus, plants have evolved complex chemical control mechanisms involving plant hormones. This allows them to adjust their growth to optimize energy capture and maintain their survival.
