A complete green flowering plant consists of six organs: root, stem, leaf, flower, fruit and seed, and each organ has certain physiological functions.

Plants absorb water and inorganic salts through roots and transport them to other parts such as leaves through stems for other parts to use. They mainly synthesize organic matter through photosynthesis in chloroplasts of mesophyll cells, so roots, stems and leaves belong to vegetative organs. After the flowers open, fruits and seeds are formed by pollination and fertilization, and then the seeds are used to breed offspring, so flowers, fruits and seeds belong to reproductive organs.

The sweet potato we eat is the root of the plant and the vegetative organ. Sweet potato is also called Ganchu, Sweet Potato, Bamboo Tree, Sweet Potato, Fanru, Dried Sweet Potato, Jade Pillow Potato, Sweet Potato, Sweet Potato, Yam, Sweet Potato, Sweet Potato, Goose, and Meng Sweet Potato. Millet has round, oval or spindle-shaped tuberous roots in the underground part, and the stems are horizontal or ascending, with occasional twining and multi-branching. The shape and color of leaves often vary with varieties, usually with wide oval shape and different petioles. Cymes axillary, capsules ovoid or oblate, 1-4, usually 2, glabrous.

Sweet potato is a kind of food crop with high yield and strong adaptability, which is closely related to industrial and agricultural production and people's life. Truffle is not only the main grain, but also an important raw material for food processing, starch and alcohol manufacturing industries. Roots, stems and leaves are excellent feeds.
