EVERYDAY SCIENCE

Detailed explanation-1: -xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.

Detailed explanation-2: -Water from the soil enters the root hairs by moving along a water potential gradient and into the xylem through either the apoplast or symplast pathway. It is carried upward through the xylem by transpiration, and then passed into the leaves along another water potential gradient.

Detailed explanation-3: -Xylem is the tissue which transports water and minerals in plants.

Detailed explanation-4: -Xylem tissue transports water and nutrients from the roots to different parts of the plant, and includes vessel elements and tracheids, both of which are tubular, elongated cells that conduct water.

Detailed explanation-5: -Transpiration is ultimately the main driver of water movement in xylem. The cohesion-tension model works like this: Transpiration (evaporation) occurs because stomata are open to allow gas exchange for photosynthesis.
