How do plants transport materials? Flashcards
What do xylem vessels transport?
Water / minerals
What do phloem vessels transport?
Sucrose and amino acids
In which direction is water transported in a plant?
From source to sink
In which direction are sucrose and amino acids transported in a plant?
From source to sink
Which plant transport vessel transports sucrose and amino acids?
Phloem
Which plant transport vessel carries water and minerals?
Xylem
What is the most common source of sucrose for a plant in summer?
Leaf
What is the most common source of sucrose for a plant in winter
Root
Define transpiration
Loss of water vapor from plant leaves by evaporation of water at the surface of the mesophyll cells followed by diffusion of water vapor through the stomata
Define translocation
Movement of sucrose and amino acids in phloem
What is the name of the process by which sucrose and amino acids are transported from source to sink in the phloem?
Translocation
What is the name of the process by which water and minerals are transported from roots to leaves in xylem?
Transpiration
What is the function of a root hair cell?
Absorb water and mineral from the soil
What is the name of the plant cell that absorbs water from the soil?
Root hair cells
Why do root hair cells have a large surface area?
To absorb as much water and mineral as possible
