A complete green flowering plant consists of six major organs: roots, stems, leaves, flowers, fruits and seeds. The plant absorbs water and inorganic salts through the roots and transports them to other parts such as leaves through the stems. For use by other parts, photosynthesis is mainly performed in the chloroplasts of mesophyll cells to synthesize organic matter, so roots, stems, and leaves are vegetative organs. After a flower opens, it undergoes pollination and fertilization to form fruits and seeds, which are then used to reproduce offspring. Therefore, flowers, fruits and seeds are reproductive organs. Potatoes are the underground roots of plants, which belong to roots and are vegetative organs; peanuts are the fruits produced after flowers bloom and belong to reproductive organs.
