What type venation is potato?

Potatoes do not have venation, as they are underground stems, not leaves. Venation refers to the pattern of veins in leaves, which are responsible for transporting water and nutrients.

If you're asking about the leaves of the potato plant, they have reticulate venation. This means the veins are arranged in a network, similar to a net, with branching veins connecting to a main central vein.
