Vascular Tissue

Vascular tissue is a complex network of specialized cells found in higher plants. It is responsible for the transport of water, nutrients, and other essential substances throughout the plant. There are two main types of vascular tissue: xylem and phloem.

Xylem

Xylem is responsible for transporting water and minerals from the roots to the rest of the plant. It is made up of several types of cells, including tracheids and vessel elements. These cells are arranged in such a way that they form long, interconnected tubes, allowing for efficient transport of water and nutrients.

Phloem

Phloem, on the other hand, is responsible for transporting sugars, amino acids, and other organic compounds produced by photosynthesis in the leaves to other parts of the plant. Phloem consists of sieve tube elements and companion cells, which work together to facilitate the movement of these organic substances throughout the plant.

Functions of Vascular Tissue

Vascular tissue plays a crucial role in the growth, development, and survival of plants. It provides structural support and helps in the distribution of essential substances, enabling the plant to carry out necessary physiological processes.
