DENDROLOGY

Detailed explanation-1: -The two primary vascular tissues are xylem, which transports water and dissolved minerals from the roots to the leaves, and phloem, which conducts food from the leaves to all parts of the plant.

Detailed explanation-2: -Phloem transports carbohydrates, produced by photosynthesis and hydrolysis of reserve compounds, to sink tissues for growth, respiration and storage. At photosynthetic tissues, carbohydrates are loaded into phloem (Rennie and Turgeon 2009), a process that raises the solute concentration.

Detailed explanation-3: -Xylem and phloem are examples of vascular tissues. The function of vascular tissues is to conduct water and food different part of the plant body. Vascular tissues are complex permanent tissues because they are made of more than one cell type.
