Explanation

Xylem is the plant tissue that carries water and minerals upward from roots to leaves and stems. Xylem cells form long tubes like tiny pipes inside the plant. Water moves through these tubes in one direction only, from bottom to top.

Roots absorb water and dissolved minerals from the soil. The xylem pulls this water up through the plant using a combination of root pressure and evaporation from leaves. This upward movement can lift water over 100 meters in tall trees.

Phloem transports sugar made in leaves to other plant parts, which is different from xylem. Epidermis is the outer protective layer of plants. Parenchyma cells store food and provide support but do not transport water long distances.
