Detailed explanation-1: -Its function is the transportation of food and nutrients such as sugar from leaves to other parts of the plant. This movement of substances is called translocation. Additional Information: Phloem is the food transporting component of the plant.
Detailed explanation-2: -Phloem sap travels through perforations called sieve tube plates. Neighboring companion cells carry out metabolic functions for the sieve-tube elements and provide them with energy. Lateral sieve areas connect the sieve-tube elements to the companion cells.
Detailed explanation-3: -Phloem is a highly specialised vascular tissue that forms an interconnected network of continuous strands throughout a plant’s body. It transports sugars, nutrients, and a range of signalling molecules between leaves, roots, flowers, and fruits. As a result, phloem is central to plant function.
Detailed explanation-4: -Kallarackal and Komor (1989) demonstrated that glucose and fructose are transported in the phloem of Ricinus communis if the cotyledons are incubated in these sugars.
