When a plant leans toward the sun, what is this character of life
likoan [24]

Answer:

Among the seven characteristics in life, the one should be sensitivity. It is where living organisms detect and react to stimulus or changes to the environment.

Specifically among plants, this change is called a tropic response, or tropism for short. Plants reacts to aspects like light, gravity, or water.

This response is controlled by a plant hormone called auxin. Auxin is produced at the tip of the plant, and they diffuse among the plant. The auxin accumulates at the side of the plant that doesn't receive as much sunlight, and auxin can stimulate its growth on that side so the plant bends. That's how a plant bending works.

Anyways, the answer to the question should be sensitivity.
