Beans are a type of legume that are widely consumed around the world. Here is a brief description of the labeled parts of a bean:
- Seed coat: The outer covering of the bean seed, which protects the embryo inside.
- Hilum: The scar on the bean seed where it was attached to the pod.
- Radicle: The embryonic root of the bean seed, which grows downward and forms the primary root of the plant.
- Cotyledon: The embryonic leaf of the bean seed, which stores nutrients and provides energy for the developing plant.
- Plumule: The embryonic shoot of the bean seed, which grows upward and eventually forms the stem and leaves of the plant.
- Micropyle: The small opening on the surface of the bean seed through which water and nutrients can enter.
- Pod: The fruit of the bean plant, which contains the seeds and is typically long and narrow in shape.
- Stalk: The stem of the bean plant that supports the pods and leaves.
- Leaf: The green, flat structure that grows from the stalk and is used in photosynthesis.
- Petiole: The stalk that attaches the leaf to the main stem.
- Stem: The main supporting structure of the bean plant that connects the roots and leaves.
These are the main labeled parts of a bean. Different varieties of beans may have variations in size, shape, and color, but these basic parts are common to all.
