Structure of phloem cell
WebMay 4, 2024 · Cells of the pericycle and procambium (the meristematic tissue between the primary phloem and xylem) begin division, and form a vascular cambium around the primary xylem. The vascular cambium then divides to form secondary xylem on the inside and secondary phloem on the outside. WebSieve cells are long, conducting cells in the phloem that do not form sieve tubes. The major difference between sieve cells and sieve tube members is the lack of sieve plates in sieve cells. They have a very narrow diameter and tend to be longer in length than sieve tube elements as they are generally associated with albuminous cells.
