VASCULAR TISSUE Meaning and
Definition
-
Vascular tissue is a specialized type of tissue that is found in higher plants and is responsible for the transportation of fluids such as water, nutrients, and sugars throughout the organism. It is composed of two main components: xylem and phloem.
Xylem is the component that transports water and dissolved minerals upwards from the roots to the rest of the plant. It is made up of several types of cells, including vessel elements and tracheids, which form long continuous tubes. These cells are specially adapted to withstand pressure and provide structural support to the plant. Xylem vessels are dead at maturity, allowing for faster transport due to the absence of cell contents.
Phloem, on the other hand, transports sugars, amino acids, hormones, and other organic molecules both upwards and downwards within the plant. It is composed of specialized cells called sieve tube elements, which are living cells connected by sieve plates. Companion cells, located adjacent to sieve tube elements, provide them with metabolic support. Phloem cells actively transport organic molecules, using a process known as translocation, powered by energy from ATP.
The combination of xylem and phloem constitutes the vascular system of a plant, forming a network of interconnected tubes that spans the entire organism. Vascular tissue allows plants to efficiently and effectively distribute essential resources to various parts of the plant, such as leaves, stems, and roots, enabling growth, development, and overall survival.

Etymology of VASCULAR TISSUE
The word "vascular tissue" has a Latin etymology. The term "vascular" comes from the Latin word "vasculum", meaning "a small vessel". The word "tissue" also originates from Latin, derived from the word "tessere", meaning "to weave". Therefore, "vascular tissue" refers to a woven or connected network of blood vessels in an organism.
