Answer:
1. Creepers are plants with weak stem that grow along the ground, around another plant, or up a wall by means of extending stems or branches. They have very fragile stems that can neither stand erect nor support all of its weight. The examples of creepers are watermelon, pumpkin, sweet potato, etc.
2. A plant of wheat has fibrous root.
3. The shoot system consists of the stems and leaves of the plant. More specifically, it includes the nodes, internodes, axillary buds, terminal bud and leaves. The leaf has four parts as well, the stalk, blade, veins and petiole.
4. Venation is the phenomenon of arrangement of veins in the lamina of the leaf surface. It is of three types, reticulate, parallel and furcate venation. In reticulate venation, veins form the network like structure.
