How do peanuts grow?

1. After flowering and pollination of peanuts, the ovary stalk at the base of the ovary is continuously elongated, and fruit needles grow from withered flower tubes;

2. The fruit needle elongates rapidly longitudinally, grows upward first, and then the ovary stalk hangs on the ground;

3. In the process of extension, the epidermal cells of ovary stalk are lignified to protect the young fruit needles from being buried in the soil;

4. When the needle is 5-6 cm long, the ovary begins to lie horizontally, becoming fat and white, and hair grows on the body surface, directly absorbing water and various nutrients for growth and development;

5. Each seed is formed one by one, the epidermis gradually shrinks, and the fruit gradually matures to form peanuts.
