I think the watermelon is a dicot, so the leaf venation will be reticulated, or netted.
No, not all dicot leaves have netted venation. While most dicot leaves do have netted venation, some dicot leaves have parallel venation, particularly those in the families Araceae and Arecaceae.

The two types of netted venation arrangements are pinnate venation, where the veins run parallel to each other along the midrib of the leaf, and palmate venation, where the veins radiate outward from a single point at the base of the leaf.

Venation is the arrangement of veins in an insect's wing or the leaf of a plant. Such venation is said to be netted if the smaller vessels branch from the larger ones either as in a feather or like the fingers of a hand. Please see the link.
Venation is how a the leaf veins are organized. Netted venation is when there are larger veins with many smaller veins branches making a type of web pattern.
