The phloem plays a vital role in transporting sugars and organic materials throughout plants. This system involves various specialized cells like sieve elements, companion cells, parenchyma cells, and phloem fibers. Mature sieve elements lack certain organelles and have non-lignified cell walls, mak

Secondary growth, resulting from cambial cell division, thickens stems and roots in plants. This process involves cambium, a tissue layer between xylem and phloem, responsible for secondary growth. Cambium ray initials give rise to vascular rays and secondary xylem/phloem. The seasonal activity of c
