Sieve Tube Element Nucleus at Gary Razo blog

Sieve Tube Element Nucleus. revision notes on 7.1.4 phloem sieve tube elements for the cie a level biology syllabus, written by the biology experts at save my exams. sieve element, in vascular plants, elongated living cells of the phloem, the nuclei of which have fragmented and disappeared and the transverse end walls of which are pierced by sievelike groups of pores (sieve plates). this chapter reviews the fundamentals of phloem development and structure with particular focus on their. They are the conduits of food (mostly sugar) transport from the leaves to the rest of the plant. in order to generate a tube system of low resistance, sieve elements loose most of their cellular components such as nucleus, cytoskeleton, ribosomes, tonoplast etc. although the cellular infrastructure has been minimized by loss of the nucleus, the vacuole, ribosomes, golgi,. at the same time, the nucleus disintegrates and the cell assumes the features of the enucleated sieve tube element. the sieve tube member is a mature phloem cell involved with long distance movement of food material.
