Urkle decided he wanted to test the effects of watering his plants with cold coffee. For a week he watered one group of plants cold coffee. He ignored the other group of plants. Urkle has no idea what might happen to plants that receive coffee. What is wrong with Urkle's experimental design?     If Urkle wants to test the effects of cold coffee on plant growth, he should water his control group with cold water.   If Urkle wants to test the effects of cold coffee on plant growth, he should water the plants in the other group with Dr. Pepper.   If Urkle wants to test to test the effects of cold coffee on plant growth, he should water the plants in the other group with hot coffee.   If Urkle wants to test the effects of cold coffee on plant growth, he can ignore the control group as long as he makes sure both groups get the same amount of sun.

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.
