1. SUGAR TRANPORT IN PLANTS
The Pressure Flow Theory best eksplains the
movement of sugars from the leaves to the roots
2. SUGAR TRANPORT IN PLANTS
The leaf cells are called the “Source” because
sugars are made there
3. SUGAR TRANPORT IN PLANTS
The root cells are called the “Sink” because sugars
are stored there
4. SUGAR TRANPORT IN PLANTS
Xylem Phloem
“Source”
Leaf Cell
From the root system To the root system
5. SUGAR TRANPORT IN PLANTS
Xylem Phloem
“Source”
Leaf Cell
From the root system To the root system
6. SUGAR TRANPORT IN PLANTS
Xylem Phloem
“Source”
Leaf Cell
From the root system To the root system
7. SUGAR TRANPORT IN PLANTS
Xylem Phloem Water molecules move up the
Xylem vessels by tranpiration
“Source”
Leaf Cell
From the root system To the root system
8. SUGAR TRANPORT IN PLANTS
Xylem Phloem Water molecules move up the
Xylem vessels by tranpiration
“Source”
Some water molecules move into
the leaf cell by osmosis
Leaf Cell
From the root system To the root system
9. SUGAR TRANPORT IN PLANTS
Xylem Phloem Water molecules move up the
Xylem vessels by tranpiration
“Source”
Some water molecules move into
the leaf cell by osmosis
Sugar molecules created by the
leaf cells are actively transported
to the Phloem cell system
Leaf Cell
From the root system To the root system
10. SUGAR TRANPORT IN PLANTS
Xylem Phloem Water molecules move up the
Xylem vessels by tranpiration
“Source”
Some water molecules move into
the leaf cell by osmosis
Sugar molecules created by the
leaf cells are actively transported
to the Phloem cell system
The hipertonic solution in the
Phloem causes water to move
from adjacent cells to the Phloem
cell system
Leaf Cell
From the root system To the root system
11. SUGAR TRANPORT IN PLANTS
Xylem Phloem Water molecules move up the
Xylem vessels by tranpiration
“Source”
Some water molecules move into
the leaf cell by osmosis
Sugar molecules created by the
leaf cells are actively transported
to the Phloem cell system
The hipertonic solution in the
Phloem causes water to move
from adjacent cells to the Phloem
cell system
Sugar and water molecules move
to the root system
Leaf Cell
From the root system To the root system
