Detailed explanation-1: -phloem, plant vascular tissue that conducts foods made in the leaves during photosynthesis to all other parts of the plant. Phloem is composed of various specialized cells called sieve elements, phloem fibres, and phloem parenchyma cells.
Detailed explanation-2: -Plants have two transport systems-xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.
Detailed explanation-3: -phloem: The part of a plant that carries sugars and other products of photosynthesis from where they are made in the leaves to where they are needed.
Detailed explanation-4: -Phloem is the vascular tissue that transports carbon (photosynthates) from the leaves to basal parts of the plant, and vascular cambium is undifferentiated tissue responsible for secondary growth and repair of damaged phloem (Lalonde et al., 2004).
Detailed explanation-5: -Their resistance to stretching increases the turgor pressure at the source end of a sieve tube. At sinks, sugars are transported out of the phloem into surrounding cells.
