Plant Transportation Substances Flashcards
(19 cards)
What kind of membrane does a plant have?
Selective permeable membrane
What kind of transport is used to move H+ ions from the cytoplasm to the extracellular fluid?
Active transport
What does a cell use to move the H+ ions outside the cell?
ATP
Proton pumps establish what?
Gradient
Is ATP used for sucrose transport?
No, the sucrose will travel across the membrane with a H+ ion
Sucrose produced in the leaf cell needs to be transported into the what?
Phloem
What is the difference between a pump and a transporter?
Pump- pump H+ ions out of cell (creates electrical gradient)
Transporter- substance joins H+ ion and enters the cell together
What kind of transport is H+ and neutral solutes?
Passive transport
What mineral nutrient is being co-transported with H+ ions in a root cell?
NO3- (Nitrate)
Is ATP needed for NO3- transport?
No, uses electrical gradient
The more ________ a water potential, the more water is attracted to the cells
Negative
What does it mean if a cell is flaccid?
Limp from lack of water
What does water potential predict?
Flow of water
What does it mean to be plasmolyzed?
The cell shrinks and pulls away from the cell wall due to hyperosmotic solution.
What has a more negative water potential in a hyperosmotic solution?
Environment
What has a more negative water potential in a hypoosmostic solution?
Cell
What does it mean to be turgid?
The cell is swollen due to the hypoosmotic solution
What does it mean if a plant is wilting?
Drooping of leaves as a result of the flaccid cells
What does it mean if a plant is turgid?
Leaves and stems are perked up as a result of water in cells
