Wild Card
100
This property of water allows this insect to stand on top of it without falling in.
What is surface tension?
100
"Water-fearing" (unable to mix with water)
What is hydrophobic?
100
Type of transport that does not require any energy.
What is passive transport?
100
The substance that moves during osmosis.
What is water?
100
The semi-permeable layer on the outside of a cell controlling what goes in and out.
What is the cell membrane?
200
The type of bond that holds individual water molecules together.
What are hydrogen bonds?
200
They make up the bilayer of the cell membrane!
What is a phospholipid?
200
Basic movement of small molecules from high concentration to low concentration.
What is diffusion?
200
Type of solution where water would rush into the cell causing it to swell.
What is a hypotonic solution?
200
The partial negatively charged element in water.
What is oxygen?
300
The property of water that allows water to stick to other water molecules.
What is cohesion?
300
The head of a phospholipid has this property
What is hydrophilic?
300
This is required for active transport (like endocytosis and exocytosis) to occur.
What is energy (or ATP)?
300
The direction water will move in this example of osmosis:
What is out of the cell?
300
The metaphor I used to compare simple diffusion across the cell membrane to New York City.
What are birds?
400
An example is capillary action. Water is able to stick to other polar substances because of this property of water.
What is adhesion?
400
Type of protein that does not go all the way through the cell membrane. (Sits on the outside)
What is a peripheral protein?
400
This integral protein is responsible for osmosis.
What is aquaporin?
400
Type of solution where water would rush out of the cell and it shrinks.
What is a hypertonic solution?
400
The primary macromolecule responsible for the structure of the cell membrane
What is a lipid (or phospholipid)?
500
A molecule that has oppositely charged ends
What is polar? (Ex: H+ and O- in H2O)
500
The model that describes the cell membrane as bendable and flexible, full of many different structures.
What is the fluid mosaic model?
500
Larger molecules, using a channel protein, going from high concentration to low concentration.
What is facilitated diffusion?
500
Type of solution where there is equal movement of water into and out of the cell.
What is an isotonic solution?
500
All integral proteins have this property that allows them to fit through the cell membrane and pass materials through it.
What is amphipathic?
