The morphology of the bean plant can be distinguished as follows:
1. Roots
Bean plants have tap roots and fibers. The riding roots grow straight to a depth of 11-15 cm, while the fibrous roots grow spread out and not deep. The roots of bean plants can grow well, when the soil is fertile and there is no stagnation of water or flooding.
2. Stems
The stems of the bean plant are not woody, not hard, and bookish. The books are located close to the ground surface, this book is where the leaf stalks are attached. In general, the height of the stem of a bean plant with an upright type is around 40 cm from the soil surface.
3. Leaves
The leaves of the bean plant have an oval shape, the tip of the leaf is pointed, the leaf edge is flat, hairy and has fine hair and has pinnate spines. Each branch of the plant has 3 leaves that are located opposite each other. The size of the leaves varies greatly, depending on the variety, the small leaves have a width of 6-7.5 cm and a length of 7.5-9 cm. while large leaves have a width of 10-11 cm and a length of 11-13 cm.
4. Flowers
The flower of the bean plant is elliptical, with a length of 1.3 cm and a width of 0.4 cm in the middle. The bean flower has a small size, the petals are 2 pieces and the bottom or the base of the flower is green. Generally, the bean flower has a stalk with a length of 1 cm, the flower crown has various colors, there are white, light purple and dark purple, depending on the variety.
