The incorrect answer is Venation.Explanation:The part of the leaf by which it is attached to the stem is called a petiole.The broad, green part of the leaf is called the lamina.The lines on the leaf are called veins.These give support and transport water and mineral through the leaf.A prominent line in the middle of the leaf is called the midrib. The design made by veins in a leaf is called the leaf venation.If this design is net-like on both sides of the midrib, the venation is reticulate.Additional InformationVenation may be of two types:Reticulate venation: When the veinlets form a network, the venation is termed as reticulate. This is found in Dicot plants.Parallel venation: When the veins run parallel to each other within a lamina, the venation is termed as parallel. This is found in Monocot plants.Based on the presence of reticulate venation and parallel venation, Dicot can be differentiated from Monocot plant.
