Midrib

Midrib is the thickest vein in the middle of the leaf. It separates the leaf lamina into two parts in a dicot leaf. It forms lthe eaf's skeleton and provides mechanical support to it. It also helps in the transport of water and minerals to different cells of leaf. It transports synthesised food from leaf to stem from where it is carried to different parts of the plant.
