Detailed explanation-1: -Phloem is living tissue, responsible for transporting food and other organic materials. Xylem consists of dead cells (parenchyma is the only living cells present in the xylem). Pholem mainly contains living cells (fibres are the only dead cells in the phloem).
Detailed explanation-2: -The phloem is a complex tissue and is formed typically by three cell types, the sieve elements, the parenchyma cells, and the sclerenchyma cells (Figure 2a–d).
Detailed explanation-3: -It is a living tissue, which is responsible for transporting food and other organic materials. Xylem generally consists of dead cells (parenchyma is the only living cell present in the xylem).
Detailed explanation-4: -Hint: In phloem both companion cell and sieve tubes are living cells.
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.
