Final answer:
The option not showing plant life characteristics is 'c. The leaves on a plant are moved by the wind,' which is a passive occurrence, not an active response to stimuli.
Step-by-step explanation:
The option that is NOT an example of plants demonstrating the characteristics of life is c. The leaves on a plant are moved by the wind. This is because plants moving due to the wind is not an active response from the plant, but rather a passive occurrence. In contrast, the other options provided (a, b, and d) each describe a scenario in which the plant is actively responding to its environment or going through a life process. Plants respond to light through a process known as phototropism, where they grow towards the light source. Plants also make adaptations to survive in varying environmental conditions. The growth stages that plants go through demonstrate their ability to develop according to the surrounding conditions, signaling their active life processes.
