100
The smallest units of life
What are cells?
100
The structure that regulates what enters and exits the cell?
What is the cell membrane?
100
Transport that does not require energy.
What is passive transport?
100
Movement of molecules across a cell membrane that requires energy.
What is active transport?
100
Osmosis is considered this type of transport.
What is passive transport?
200

Water fearing and water loving. 

What is hydrophobic and hydrophilic? 

200

Four ringed steroid structure in the cell membrane that keeps it fluid (hint: it is in your bloodstream too). 

What is cholesterol?

200
The movement of molecules from high concentration to low concentration.
What is diffusion?
200
Active transport that keeps sodium from building up in the cell.
What is a sodium potassium pump?
200
This solution has an equal number of solutes in and outside the cell.
What is isotonic.
300
A structure within a cell that performs a specific function.
What is an organelle?
300

A protein that opens and closes to the environment to move things into or out of the cell. 

What is a carrier protein?

300
Diffusion of water.
What is osmosis?
300

Transports molecules into the cells. 

What is endocytosis? 

300
Solution with high solute concentrations on the outside of the cell, making a cell shrink.
What is hypertonic?
400
Which type of molecule forms a lipid bilayer within a cell?
What is a phospholipid?
400

These act as openings to allow molecules to move in and out of the cell. 

What are channel proteins?

400
The movement of molecules across a membrane with the help of a protein. Does not require energy.
What is facilitated diffusion?
400
Vesicles transport wastes out of the cell through this process.
What is exocytosis?
400
Solution with a low solute concentration on the outside, making the cell swell.
What is hypotonic?
500

A rigid structure that has to be porous to let membrane contents in or out (hint: not found in animal cells). 

What is the cell wall?

500

They function as antennae or signal receptors for the membranes (hint: one of the macromolecules).

What are carbohydrates?

500
These types of molecules move easily through a cell membrane.
What are small, nonpolar molecules.
500
During active transport molecules move in this direction across the cell membrane.
What is from low concentration to high concentration?
500
After diffusion or osmosis a cell will be in this state.
What is homeostasis?
