NEET BIOLOGY

Detailed explanation-1: -The phloem is responsible for transporting substances like sugars and amino acids, which are primarily produced in the photosynthetic parts of the plant like its leaves.

Detailed explanation-2: -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.

Detailed explanation-3: -At their “source”-the leaves-sugars are pumped by active transport into the companion cells and sieve elements of the phloem. As sugars (and other products of photosynthesis) accumulate in the phloem, water enters by osmosis.In the figure, sugar molecules are represented in black, water molecules in red.)

Detailed explanation-4: -Xylem and phloem are the two vascular tissues that are responsible for the transport of substances in plants. Phloem helps the bidirectional transport of food whereas xylem helps in the unidirectional transport of water.
