Transpiration & Translocation Flashcards
What do phloem tunes transport
Food mainly sugars made in the leaf to the rest of the plant for immediate use or storage
Why do phloem walls have small pores
To allow sap to flow through
Is. Phloem transpiration or translocation
Translocation
In what direction does the transport in the phloem go
Both directions
what is cell sap
A liquid that’s made up of the substances being transported and water
What is the xylem rube made of
Dead cells
How is the xylem tube strengthened
A material called lignin
What do xylem tubes carry/transport
Water and mineral ions
Where does the xylem transport to and from
Transports from the roots to the stem and leaves
What is transpiration
The movement or water from the roots through the xylem and out of the leaves
What is transpiration caused by
Evaporation and diffusion of water from a plants surface
Where does most transpiration happen
In the leaves
What does the evaporation cause in the leaf
A slight shortage of water in the leaf
So more water is drawn up from the rest of the plant through the xylem vessels to replace it
Where is more water drawn up from
The roots
What is transpiration (2) just a…
Just a side effect of the way leaves are adapted for photosynthesis
