You are part of a desert plant research team trying to discover crops that will be productive in arid climates. You discover a plant that exhibits multiple drought responses. What can you conclude about the molecules responsible for these responses? O They alter the amount of energy available to the plant. O They respond to air temperature changes. O They can reset the biological clock. O They are modified by changes in moisture.

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.
