HORTICULTURE

Detailed explanation-1: -Phloem is the plant tissue that helps in carrying the food to different parts of a plant. Phloem in the plants transfers food made in leaves to all other parts of the plant. It is composed of cells called sieve tubes, companion cells, phloem fibres, and phloem parenchyma cells.

Detailed explanation-2: -Phloem is one of the two tissues that make up the plant’s long-distance transport system, the other being xylem. Phloem translocates water and products of photosynthesis from source tissues to the sink regions where they are utilized or stored.

Detailed explanation-3: -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.
