One experiment in phototropism involved cutting off the tips of grass seedlings before exposing them to light from one side. The decapitated seedlings did not bend toward the light. A valid conclusion from this experiment would be that
◦ a foil cover over the tip of the seedlings would cause them to bend.
◦ hormones are produced in all parts of the plant.
◦ plants cannot engage in photosynthesis without the tip of the plant.
◦ light is perceived by the tip of grass plants.
