Definition - What does Parallel venation mean?
Parallel Venation describes a condition in leaves when all the veins of a leaf are parallel to each other. Typically, this is a characteristic found in most monocot leaves and correlates with their extended leaf shape and wide leaf base. In such leaves, the veins usually run parallel to one another from the base of the leaf to the tip of the leaf.
MaximumYield explains Parallel venation
In order to understand parallel venation, it is important to understand how leaf veins work. Leaves in plants represent the vascular structures. The veins in leaves play a crucial role in water retention and photosynthesis. Though some vascular plants express a single vein, most plants have leaves with patterns or venation.
In parallel venation, the veins create a parallel structure starting from the base to the tip of the leaf, resulting in a net-like pattern being formed on both sides of the midrib. There are two tupes of parallel venation: pinnately and palmately. Pinnately parallel venation have a varied mid leaf section while palmately have a varied base and tip leaf section. Monocots like banana and bamboo are examples of plants with parallel venation.
