Involvement Of K+ In Leaf Movements During Suntracking Involvement of K+ in Leaf Movements During Suntracking Introduction Many plants sew their leaves in answer to directional light signals. Heliotropic movements, or movements that are affected by the sun, are common among plants belonging to the families Malvaceae, Fabaceae, Nyctaginaceae, and Oxalidaceae. The leaves of many plants, including crotalaria pallida, exhibit diaheliotropic movement. C. pallida is a woody shrub native to punt Africa. Its trifoliate leaves are connected to the petiole by 3-4 mm long pulvinules (Schmalstig).
In diaheliotropic movement, the plants leaves are orient perpendicular to the suns rays, thereby maximizing the interception of photosynthetically state-of-the-art radiation (PAR). In some plants, but not all, his result occurs particularly during the morning and late afternoon, when the light is coming at more of an angle and the water stress is not as severe (Donahue a...If you want to get a full essay, rate it on our website: OrderCustomPaper.com
