Importance of Complex Tissues - QS Study
QS Study

In respect of physiological and economic aspects, complex tissues are of great importance.

Physiological importance:

  • Complex tissues perform the duty of conduction of raw food materials to leaves and prepared food materials to all the living cells.
  • Beside preparation of food, water is necessary for various reactions. This water is conducted from root to stem through the complex tissue named xylem.
  • Through xylem tissue dissolved minerals along with water also passes upwardly.
  • Water used in transpiration also moves to leaf through xylem tissue.
  • Complex animal bodies demand connective tissues made up of organic and inorganic materials that provide support and structure.

Economic importance

  • The most important economic crop in Bangladesh is jute fiber. Jute fiber is the secondary phloem or bast fiber.
  • The wood we use, in the construction of houses, in making furniture, boat or musical instruments or as fuel, is the secondary xylem.
