1. Roots: The roots of a bean plant are typically long, fibrous, and branched, and they extend deep into the soil. They anchor the plant in place and absorb water and nutrients from the soil.

2. Stem: The stem of a bean plant is usually erect and cylindrical, and it can be either hollow or solid. It supports the leaves, flowers, and fruits of the plant, and it also transports water and nutrients between the roots and the leaves.

3. Leaves: The leaves of a bean plant are typically compound, meaning that they are made up of multiple leaflets that are arranged in a palmately or pinnately compound manner. The leaves are green in color and they contain chloroplasts, which are organelles that perform photosynthesis, converting sunlight into energy that the plant can use to grow and produce food.

4. Flowers: The flowers of a bean plant are typically white, purple, or pink, and they are usually arranged in clusters or racemes. Each flower consists of five petals, five sepals, and numerous stamens and pistils. The flowers of a bean plant are self-pollinating, meaning that they are fertilized by pollen from the same flower or from another flower on the same plant.

5. Fruits: The fruits of a bean plant are typically legumes, which are pods that contain seeds. The legumes of a bean plant are usually green in color when they are immature, and they turn brown or black when they are mature. The seeds of a bean plant are typically oval in shape and they come in a variety of colors, including black, brown, white, and red.
