Fásszövetek

Fásszövetek, meaning woody tissues in Hungarian, refers to the specialized plant tissues that provide structural support and transport water and nutrients within a plant. These tissues are primarily found in woody plants like trees and shrubs. The most significant fásszövetek are xylem and phloem. Xylem is responsible for transporting water and dissolved minerals from the roots to the rest of the plant. It also plays a crucial role in mechanical support, giving the plant its rigidity. The cells within xylem are typically dead at maturity and are characterized by their thickened, lignified cell walls.

Phloem, on the other hand, transports sugars produced during photosynthesis from the leaves to other parts of the plant where they are needed for growth or storage. These sugars, primarily sucrose, are moved throughout the plant via sieve tubes. Phloem cells are living at maturity but have reduced cellular contents. Together, xylem and phloem form the vascular system of the plant, essential for its survival and development. The continuous production and accumulation of these tissues over time contribute to the formation of wood, which is a defining characteristic of woody plants. The structure and composition of fásszövetek are vital for understanding plant physiology, ecology, and the properties of wood used in various applications.
