Question
Chapter 44.9, Problem 1CYL
Summary Introduction
To determine:
How sugar solution moves in phloem and why they always move from sources to sinks of sugars.
Introduction:
Xylem and phloem are two important tissues involved in the transportation system in the plant. These tissues are also known as vascular bundle. Phloem mediated food transportation is bi-directional and is transported from source to sink.

- How are sugars transported in phloem? the formation of starch from sugar in the sink increases the osmotic concentration high turgor pressure in source sieve-tube elements pushes phloem sap to sink sieve-tube elements with low turgor pressure water is actively transported into the source region of the phloem to create the turgor pressure needed the combination of a high turgor pressure in the source and transpiration water loss from the sink moves solutes through phloem conduitsarrow_forwardBut how are the two types of mesophyll involved? From what I understand, CO2 enters the stomata, and then the citric acid cycle of the mitochondia in the mesophyll use the carbon atoms do produce glucose, which then goes through phloem loading and it either used or stored. My question, I guess, is how exactly are the two types of mesophyll involved? Is only one used or are both used at different times in the production of the glucose?arrow_forwardHow is the movement of water through the xylem different from the movement of food through the phloem in the stem?
