If a plant has fibrous roots, what type of venation do its leaves have?
Venation refers to the system that is responsible for the arrangement of veins.
The usual form of a leaf is broad, flat, and thin (dorsiventrally flattened), which allows the leaf to maximize the surface area that is directly exposed to light and permits light to enter the tissues and reach the chloroplasts, which in turn facilitates photosynthesis.
Parallel Venation: Parallel venation is a type of leaf venation that occurs when the veins (or the nerves) are organized parallel to one another all throughout the leaf blade or lamina of the plant. Parallel venation is frequently seen in plants that have root systems composed of fibrous tissue.
Reticulation Venation: It is referred to as reticulate venation when the veins (or the nerves) are organized in a network or web-like arrangement all over the leaf blade or lamina. Reticulate venation can also refer to the arrangement of the nerves. It is frequently seen in plants that have root systems composed of taproots.
In spite of the fact that there are a great number of exceptions and complexities, they are arranged on the plant in such a way as to expose their surfaces to light in the most efficient manner possible while avoiding casting shadows on one another. Pendent leaves, which are seen on many varieties of willow and eucalyptus, are an adaptation that allows these plants to thrive in windy situations.
