In systemic dyeing, the correct process involves plants absorbing color through the stem. This method allows the dye solution to be transported throughout the plant via the vascular system, specifically through the xylem. When the dye is introduced into the water that the plant takes up through its stem, it travels up into the leaves, flowers, and other parts of the plant. As a result, the entire plant can take on the color of the dye, creating a uniform appearance.

This contrasts with absorption through the leaves, roots, or flowers, which may not effectively disperse the color throughout the entire plant. While leaves do play a role in photosynthesis and transpiration, they are not the primary site for systemic dye absorption. The roots, although they can absorb nutrients and water, are generally not involved in the absorption of dyes in this context. Flowers may take up dye if the stems carrying the dye are cut and placed in a dye solution, but they do not absorb color independently in the systemic dyeing process. The stem is the key part of the plant that facilitates the movement and distribution of color throughout its structure.
