Phloem is used to transport

Webb1 dec. 2014 · Plants transport the products of photosynthesis (food molecules) up and down the stem in phloem. The main carbohydrate transported is sucrose but phloem cells also contain lots of amino acids and a few other sugars. The mechanism by which these sugars are moved around the plant is less well understood than for water movement in … Webb8 dec. 2014 · So it can't be transported via phloem and the next choice is sucrose, being water soluble and energy efficient sucrose is chosen to be the carrier of energy from leaves to different part of the tree. Another problem exists, glucose is highly reactive and this may result in some intermediate reactions while transporting glucose.

Phloem Transport: How Plants Transport Food And Water

Webb1 dec. 2024 · Figure 17.2. 2: Sieve-tube elements are the conducting cells of the phloem in angiosperms. Assimilate travels through perforations in sieve plates (labeled sieve-tube plates), which connect stacked sieve-tube elements. Neighboring companion cells carry out metabolic functions for the sieve-tube elements and provide them with energy. Webb1 jan. 2006 · The phloem acts as a rigid-walled manifold that accumulates and loses solute in response to source and sink activities. The pressure differential is a manifestation of resistance to flow, not a cause; in an ideal system without resistance, flow would occur without a pressure differential.
