Leaves are purposely arranged by plants, primary to take in energy from the Sun. Plants undeneath the canopy of a forest, for example, will move their leaves to catch rays of sunlight penetrating the canopy. Due to the movement of the Earth, the Sun does not stay in the same position in the sky all day so the plants move and arrange their leaves accordingly in order to take full advantage of available sunlight. Some plants also arrange their leaves to trap water or insects
