Sugar Transport in Plants: Phloem Organismal Biology

Websectional area A of phloem conduits is approximately equal in angiosperms and gymnosperms (A stem ∼ 500–1000 μm2; see Ref. [8]). In contrast, phloem conduits in conifer leaves are remarkably small, with areas in the range A ∼ 3–10 μm2 [9]. While the factors that limit phloem cell size to this range Web2 Answers. They carry organic nutrients especially sucrose to all parts of the plant. Phloem is an important part of vascular system and plays a key role in material transportation, signal transmission, mechanical support and defense reaction. WebThe cell cannot function without certain organelles and must rely on the organelles of the companion cells. The companion cell is responsible for all metabolic functions of the sieve tube member. The companion cell is essential for the survival of the sieve tube member. This will cause the member to cease phloem function and kill the plant. simplegroupauth
