QUESTION: Which tissue transports water around a plant?

ANS:

  • Xylem tissue is responsible for transporting water around a plant
  • It is a complex network of cells that forms continuous tubes throughout the plant, allowing water and dissolved minerals to move from the roots to the rest of the plant.
  • Xylem tissue is composed of several types of specialized cells, including vessel elements, tracheids, fibers, and parenchyma cells.
  • The movement of water through the xylem is driven by a combination of transpiration (water loss from the leaves) and cohesion-tension forces.
  • Xylem facilitates the absorption of minerals and nutrients from the soil by the plant’s roots, which are then transported upwards to support various metabolic processes.
  • The xylem tissue provides structural support to the plant, allowing it to stand upright against gravity.
  • Xylem sap is the water and dissolved substances transported through the xylem tissue.
  • Xylem sap also contains hormones and other signaling molecules that help regulate plant growth and development.

Water transport ·        The movement of water through xylem tissue is facilitated by the cohesion-tension theory
Mineral uptake ·        Xylem tissue plays a crucial role in the absorption of minerals and nutrients from the soil by the plant’s roots, which are then transported upwards through the xylem.
Structural support ·        Xylem tissue provides mechanical support and strength to the plant
Components of xylem sap ·        Water

·        Minerals

·        Nutrients such as potassium, calcium, and nitrogen compounds

·        It also contains hormones and signaling molecules
Evolutionary adaptations ·        Xylem tissue has evolved different structural adaptations in different plant groups, such as vessel elements in angiosperms and tracheids in gymnosperms and other vascular plants.
