Detailed explanation-1: -SIEVE ELEMENTS (OF PHLOEM) Sieve elements are specialized cells that function in the conduction of sugars. They are typically associated with parenchyma and often some sclerenchyma in a common tissue known as phloem (Gr. phloe, bark, after the location of secondary phloem in the inner bark).

Detailed explanation-2: -The main conducting elements of the phloem are the sieve elements, of which there are two different types: sieve cells and sieve-tube members. Sieve cells have narrow pores, their sieve areas are quite uniform in structure, and they are distributed evenly on all walls.

Detailed explanation-3: -PHLOEM. The structural elements of phloem include sieve tubes, companion cells, phloem parenchyma and secretory cells. The sieve tube is the conducting element of the phloem.

Detailed explanation-4: -Sieve elements are specialized cells that are important for the function of phloem, which is a highly organized tissue that transports organic compounds made during photosynthesis. Sieve elements are the major conducting cells in phloem.

Detailed explanation-5: -Sieve tubes, found in angiosperms, are living cells that are associated with companion cells. The association with companion cells helps in distant transportation within the plant cells. The sieve tubes are made up of longitudinal arrangement of sieve tube members from end to end.
