What is the simplest system
Some water moved through the root via the cytoplasm of the root ce
S. The water has to cross the cell membrane, which regulated the passage of the water and did do.bed minerals
What is the apoplast system
The water moves through the cell walls and the spaces between the cells
There are no membranes to regulate the passage
How does water move up through the xylem tissue
What are evaporates from inside the leaf leaving a higher concentration of .
water From the nearest xylem Vessel enters by osmosis.
Water molecules stick together. Because of weak hydrogen bonds between them. This is called cohesion
As water molecules. Leave the xylem vessel. They pull further molecules so the whole column of water is pulled up,
Adhesion of. The water molecules to the sides of the xylem vessels stop the col from breaking column
Where does translocation occur
In the sieve tubes of the phloem tissue
What are companion cells next to the sieve tubes used for
Actively transport sugar into the sieve tubes and then water follows by osmosis
