The leaf of a tomato plant (Solanum lycopersicum) exhibits a pinnate venation pattern. This means that the primary vein, or midrib, runs along the center of the leaf, with smaller secondary veins branching off it in a feather-like arrangement. This structure helps in efficient transport of water and nutrients throughout the leaf. Additionally, the overall leaf shape and venation contribute to the plant's ability to photosynthesize effectively.
