FIBRE TRACHEIDS Meaning and
Definition
-
Fibre tracheids refer to a specialized type of elongated cells found in the xylem tissue of vascular plants. The term "fibre" alludes to the long, slender shape of these cells, while "tracheid" emphasizes their functional role in transportation.
Fibre tracheids play a fundamental role in providing mechanical support to plants and aiding in the conduction of water and nutrients throughout the vascular system. Their primary function is to strengthen the plant's structure, contributing to its overall rigidity. This is particularly crucial in woody plants, where fibre tracheids contribute to the formation of strong and durable wood.
These cells exhibit thick secondary cell walls and often possess numerous pits, which are thin areas in the cell wall that allow for the lateral movement of water and dissolved substances. The secondary cell walls are composed of cellulose and lignin, providing a sturdy and impermeable barrier against external stressors.
Fibre tracheids are vital for the transportation of water from the roots to the rest of the plant. As water evaporates from the leaves through tiny pores called stomata, a negative pressure gradient, known as tension, is created. This tension is transmitted through the xylem vessels, including the fibre tracheids, causing water to move upwards against gravity. Additionally, fibre tracheids also facilitate the transportation of minerals and nutrients dissolved in water, aiding in the distribution of essential elements throughout the plant.
Overall, fibre tracheids represent an essential component of plant anatomy, providing structural support and contributing to the efficient transport of water and nutrients throughout plants.

Etymology of FIBRE TRACHEIDS
The etymology of the term "fibre tracheids" can be broken down as follows:
1. Fibre: The word "fibre" stems from the Latin word "fibra", which originally referred to a thread or filament. Over time, the term expanded to include any slender and flexible structure. In botany, it specifically refers to cells or tissues such as fibres found in plants.
2. Tracheids: The term "tracheids" comes from the Greek word "tracheia", meaning "windpipe" or "trachea". In botany, tracheids are long, tubular cells that form the water-conducting tissue in certain plants.
Therefore, "fibre tracheids" combines the concept of slender, flexible cells (fibres) with the tubular, water-conducting cells found in plants (tracheids).
