B7.1 Plant Transport CORE Flashcards
What is the function of xylem?
To transport water and mineral ions
What is the function of phloem?
To transport sucrose
In which direction does xylem transport?
Roots to leaves
In which direction does phloem transport?
Source to sink
What is the name of the transport that happens in the xylem?
Transpiration
What is the name of the transport that happens in the phloem?
Translocation
What is the function of root hair cells?
To absorb water and minerals from the soil
Name, in order, the four parts of a plant the water passes through from soil to air
Root hair, root cortex cells, xylem, mesophyll cells
Define transpiration
The movement of water through the xylem from roots to leaves of a plant
Describe the effect of temperature on transpiration rate
Increase in temperature increases rate of transpiration
Describe the effect of humidity on transpiration rate
Increase in humidity decreases rate of transpiration
Define translocation
Movement of sucrose from source to sink in the phloem
