Name That Solution
This solution has the SAME amount of solute as the cell.
Isotonic
The diffusion of WATER across a membrane.
Osmosis
Transport that needs NO energy from the cell.
Passive transport
Plant cells have this around the membrane. Animal cells do not.
Cell wall
Hospitals put this type of solution in an IV bag.
Isotonic
A cell sits in distilled (pure) water.
Hypotonic
In osmosis, what actually crosses: the water or the salt?
Water
Particles spread from HIGH concentration to LOW.
Diffusion
A plant cell that is firm and full of water.
Turgid
Wilted lettuce gets crisp in plain water. Did water move INTO or OUT OF the cells?
Into the cells
A cell sits in very salty water.
Hypertonic
Hypertonic solution. Does more water move INTO or OUT OF the cell?
Out of the cell
Moving from LOW to HIGH costs the cell this molecule.
ATP
The word for an animal cell bursting.
Lyse (lysis)
Salt on a slug pulls water out of its cells. The salt makes this type of solution.
Hypertonic
Inside the cell: 2% salt. Outside: 8% salt.
Hypertonic
Water moves toward the side with MORE of this.
Solute (salt)
HIGH to LOW through a protein channel. Name it AND passive or active.
Facilitated diffusion. Passive.
In salty water, the plant's membrane pulls away from the cell wall.
Plasmolysis (flaccid plant)
A lost sailor drinks ocean water and gets MORE thirsty. Which way did water move in the body cells?
Out of the cells
Inside: 5% salt. Outside: 1% salt. Name the solution AND swell or shrink.
Hypotonic. It swells.
In isotonic solution the cell doesn't change size. True or false: the water has stopped moving. Say why.
False. Water moves both ways equally. (No NET change.)
The cell wraps around something big and brings it IN in a vesicle. Name it AND passive or active.
Endocytosis. Active.
A plant cell and a red blood cell both go into distilled water. Which bursts, AND what saves the other?
The red blood cell. The cell wall.
Salty ocean water floods a farm and the crops wilt. Name the solution AND the word for what happened to the plant cells.
Hypertonic. Plants become flaccid.
