Question

Molecule (1) is a __________________ that was produced by 1 shows phloem unloading/loading. Step 2 shows___________ moving Into the phloem through the process of___________. This causes high/low turgor pressure In the phloem cells.________ and_________ then travel down the phloem. 4 shows __________________ Step 5 shows ____________ moving out of the phloem and into the root cells, this causes high/low turgor pressure In the phloem cell At 6_________ is entering the xylem. The water potential xylem is higher/lower than the water potential of root cells. 8 is considered the source/sink, CHALLENGE QUESTIONS: True or False: Sugars always move down the phloem towards the roots. This diagram shows how water moves between xylem and phi in the middle of a growing season. Add new arrows to indicate direction of water and phloem sap flow in the spring, when RO act as sources and leaves act as sinks.

Explanation / Answer

Molecule 1-sugar that was produced by the mesophyll cells and shows phloem loading and unloading.

Step-2 shows water moving into the phloem by the process of osmosis.3-This causes high/low turgor pressure in the phloem cells.Sugar and water then move down the phloem cells.

Step-4- shows the sugar molecule moving into the cortex cell of the root.

Step-5 shows water moving out of the phloem cell into the root cells,this causes high and low turgor pressure in the phloem cell.

Step-6-water is entering into the xylem. 7-The water potential of the xylem is higher/lower than the water potential of the root cell.

Step-8 -source-photosynthetic leaves and sink--root cells

TRUE-sugars move down the phloem towards the roots.
