ANSWER:
Through xylem, the nutrients first move into the flower.
Step-by-step explanation:
The roots of the plant are responsible for absorbing water and nutrients from the soil. These are then provided to the vascular tissue xylem of the plants.
The xylem then transports all the nutrients to the different parts of the plant. The xylem being one of the two vascular tissues has a role of transporting 'water and nutrients' from soil to different parts of a plant.
