Crops are various plants cultivated in agriculture. Including grain crops and economic crops (oil crops, vegetable crops, flowers, grasses and trees). The food is taken by people as days, the relationship between people and food is expressed, and the reasonable meal collocation can bring health to people. The growth of crops, scientific and technological production techniques and novel industrially produced mechanical equipment capable of assisting agricultural production, the seeds are the specific propagules of gymnosperms and angiosperms, and the seeds are formed by ovules through pollination and fertilization. The seeds generally consist of 3 parts of a seed coat, an embryo and an endosperm, and some mature seeds of plants only comprise two parts of the seed coat and the embryo. The formation of seeds, which are the reproductive system of seed plants and play an important role in continued species, allows the young sporophyte ovules to be protected from the mother. The seeds are closely related to human life, and besides grains, oil and cotton which are necessary for daily life, medicinal (such as almond), seasoning (such as pepper) and beverages (such as coffee and cocoa) are all from the seeds. Plants, trees, flowers and plants are also propagated from seeds. Many seeds can be eaten, and the rice is a delicious dish on a dining table.
