Document Summary
Compare and contrast how the endocrine and neural systems do long distance communication within the mammalian body. Singals are electrical or chemical carrierd through extracellular fluid. Targets neurons, muscles, and some glands only. Effect tend to last a shorter amoun tof time. Predict how manipulating various parts of a growing plant shoot will influence auxin signaling and plant growth towards light. With tip removed plant does not bend towards light. With jello signal still passed through plant bend. With mica signal does not pass through because it is stone plant is straight. This shows that there is signal at the tip of the plant. Described two ways in which the properties of auxin in plants has parallels to the properties of hormones in animals. Auxin is a plant hromone produced at the tip travels to the dark side of the stem which binds to a receptor causing the bending.
