What did Went's experiments with the gelatin block demonstrate? A. Plants cannot be induced to bend during growth unless they are exposed to an indirect source of light. B. Light induces the coleoptile to produce a diffusible substance that moves to the growing region of a plant where it stimulates cells to elongate. C. Gelatin can enhance the movement of a soluble factor from the growing region of a plant to the coleoptile where it accelerates growth. D. When a plant tip is removed from a growing plant, the plant acquires the ability to bend toward the light

Plant sensory system

The plant sensory system is a sophisticated system that responds to environmental stimuli such as light,temperature, gravity, and touch. Research predicts that plant hormones and signaling mechanisms areresponsible for this regulation system in plants.
