Question

What is the relation between leaf venation and the type of roots?

Answer 1

Hint: Each plant species is different and has its own characteristics. In which some shows relation between arrangements of veins in their leaf and roots. There are six parts of the leaf such as apex, mid vein, secondary vein, lamina, leaf margin, petiole, and bud. The parts of roots are the primary root, lateral root, the apical meristem, a root cap, and root hairs.

Complete answer:
Plants have five major parts such as leaf, stem, fruit, flower, and roots.

Let's see the definition of venation first. Venation is the arrangement of veins in leaves. One main or primary vein is present with secondary other veins. There are two types of vein arrangements that can be seen in leaves such as parallel and reticulate venation. In parallel venation, veins are parallel and do not form a complex network. Such an example is corn leaves (maize). And in the irregular venation, veins are distributed irregularly to form a complex network. Such an example is the carrot.

The root of a plant is a part that is underground. There are five types of roots such as tap root, fibrous root, adventitious root, tuberous root, and creeping roots.

Now let's see what the relation between venation and root is. It has been observed that plants that have fibrous roots will have parallel venation and when the plant has a tap root, the plant has reticulate or irregular venation that forms a complex network which is the answer to our question.

Note: Veins are majorly composed of xylem and phloem. Xylem veins transport water from the petiole throughout the lamina. Phloem transport produces sugar (photosynthesis) out of the leaf and sends it to the rest of the plant. The major role of the root is to provide stability to plants, absorb minerals and nutrients from the soil and send them to shoot and it also stores produced food that is sucrose.
