Unit 6: Cell Transport Flashcards
Xylem
A tissue that transports water within the organism.
Phloem
A tissue that transports products of photosynthesis.
Short Distance Transport of Solutes
The movement of one cell to another.
Osmosis
The movement of molecules across the cell membrane.
Diffusion
The movement of molecules across their concentration gradient.
Water Potential
Predicts the movement of water.
Turgor Pressure
The pressure against the cell wall.
Flaccid
A cell that has lost water.
Plasmolysis
A flaccid cell pulls away from its plasma membrane and cytoplasm away from the inside of its cell wall.
Aquaporins
Proteins that increase water movement across membranes.
Transpiration
The loss of water vapor from plant.
Stomata
Where oxygen comes in and out of leaves.
Circadian Rhythm
The cycle in your body that tells you to go to sleep.
Source vs. Sink
Source is where the sugars from photosynthesis are created, while Sink is the area where the sugars are used or stored.
What allows for stomata to open and close?
The Turgor Pressure in the guard cells.
