Plant Parts
This plant, Canavalia ensiformis (often referred to in various contexts by names like Caja), utilizes several distinct anatomical structures for its survival and medicinal properties. The lush, green leaves are often the most visible part of the plant, with each individual leaf providing the surface area necessary for photosynthesis. Supporting these structures are strong, upright stems that transport nutrients throughout the organism. The reproductive cycle is completed through the production of a seed, which is contained within a specialized pod. This pod often takes the shape of a large, fleshy bean, which serves as the primary vessel for the plant's genetic material.| Plant Part | Sources | Consensus |
