Colored pencil drawing of a complete lotus plant diagram. Show the lotus flower, leaves, and stem above the water, with the lotus root and fibrous roots clearly visible below in the mud. Include detailed labels for each part: ‘Lotus Flower,’ ‘Lotus Leaf,’ ‘Underground Stem (Lotus Root),’ and ‘Root Hairs.’ Use soft, harmonious colors and fine lines to create a cohesive and educational illustration. The background should be minimal to keep focus on the labeled parts of the plant.
