Botanical Description Of Soybean Plant

The soybean plant typically appears as an erect bush with sturdy, woody stems. Its leaves are arranged alternately along the stem and consist of three individual leaflets. These leaflets can vary in shape, being either oval or lance-like, and typically measure between 3 to 10 centimeters (1.2 to 4.0 inches) in length. This foliage arrangement contributes to the plant’s lush and verdant appearance, characteristic of many leguminous plants.
