Veined leaf

A plant's leaves are the primary sites for photosynthesis. The green colour is from chlorophyll, a pigment that absorbs the energy from sunlight falling on the leaf. The veins are the vascular tissue of the leaf, moving water into the leaf and the sap produced by photosynthesis back out.
