NEET BIOLOGY

Detailed explanation-1: -The phloem is responsible for translocation of nutrients and sugar like carbohydrates, produced by the leaves to areas of the plant that are metabolically active. It is made up of living cells.

Detailed explanation-2: -Phloem consists of living cells. The cells that make up the phloem are adapted to their function: Sieve tubes-specialised for transport and have no nuclei. Each sieve tube has a perforated end so its cytoplasm connects one cell to the next.

Detailed explanation-3: -The phloem is composed of living cells specialized for the long-distance transport of soluble organic compounds. In gymnosperms transport occurs through sieve cells, which are interconnected by structures resembling plasmodesmata.

Detailed explanation-4: -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-5: -Phloem (/ˈfloʊ. əm/, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to the rest of the plant. This transport process is called translocation.
