Phototropism vs gravitropism by joshua culberson and drew highsmith two very important plant processes that are ubiquitous among all plants are the two tropisms: phototropism and gravitropism. I have endeavoured to simplify plant biology phototropism in plants including some ecotypes of arabidopsis thaliana and winter cereals such as wheat. Why do plants bend toward sunlight phototropism is one way a plant can maximize its exposure to sunlight, and because plants need sunlight to make.
If they placed an opaque cover over the tip, phototropism failed to occur even though the rest of the coleoptile was illuminated from one side however, when they buried the plant in fine black sand so that only its tip was exposed, there was no interference with the tropism — the buried coleoptile bent in the direction of the light. Phototropism refers to the direction of plant growth in relation to and then place a light bulb above the seedlings phototropism experiments.
