xylem
The roots supply nutrients and water to the plant.
Water primarily moves up plants through the Xylem along with micro-nutrients suspended in the water. The plant then produces chlorophyll through photosynthesis which is uses as food. This is a drastic oversimplification of the process, of course. But to answer your question's.
nutrients and water
The roots provide the plant with water and dissolved nutrients. The roots also serve to anchor the plant into the ground .
The roots.
Roots provides the plants with water and nutrients in which to grow. Roots holds the plant in place, this is done by the massive root system that branches off collecting nutrients for the plant.
The plant gets its water and nutrients by the roots. No roots = no water, no "food" = Death.
It extracts water and nutrients from the soil.
Absorb nutrients and support/anchor the plant (in most plants, but not all).
