How do roots and stems work together for movement of liquid within the plant
A
the roots anchor the plant in the soil while the stem holds the leaves up
B
roots produce sugar and leaves absorb water and send it down to the roots
C
the roots make water and send it up and the leaves make food and send it up to the flower
D
roots absorb water and minerals and send them up through the xylem, while the stem moves food produced in the leaves throughout the plant through the phloem
Explanation: 

Detailed explanation-1: -The phloem carries food downward from the leaves to the roots. Xylem cells constitute the major part of a mature woody stem or root. They are stacked end to end in the center of the plant, forming a vertical column that conducts water and minerals absorbed by the roots upward through the stem to the leaves.

Detailed explanation-2: -Plant stems have some very special cells called xylem. These cells form long thin tubes that run from the roots up the stems to the leaves. Their job is to carry water upward from the roots to every part of a plant.

Detailed explanation-3: -Water mostly enters a tree through the roots by osmosis and any dissolved mineral nutrients will travel with it upward through the inner bark’s xylem (using capillary action) and into the leaves. These traveling nutrients then feed the tree through the process of leaf photosynthesis.

Detailed explanation-4: -How do the plant systems work together to make the movement of the liquid possible? The roots absorb the water, minerals move up the stem, while the stem moves food produced in the leaves down to the roots.

Detailed explanation-5: -Root pressure is that force that helps to drive fluids upward into the water-conducting vessels (xylem) due to osmotic pressure in the root cells. Transpiration pull is said to be a suction force used to draw the water in an upward direction from the roots towards the leaves.
