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
Cells without a nucleus.
What are prokaryotes?
200

The hydrophilic portion of a phospholipid. 

What is phosphate head?

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
This is where the hydrophobic region of the lipid bilayer is located. 
In the middle. 
300

Diffusion of water across a membrane

What is osmosis?

300
Molecules that are too large to move in the cell are transported through this process.
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 channels to allow molecules to move in and out of the cell.
What are 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

The two organelles that are in a plant cell, but not in an animal cell?

What are cell wall and chloroplast.

500

These two words describe the property of membranes that means they allow some substances through, but not others. 

What is "selectively permeable" 

500
These types of molecules move easily through a cell membrane.
What are small, nonpolar molecules.
500

This is how cells pull in large molecules or food particles. 

What is phagocytosis?

500

After diffusion or osmosis a cell will be in this state (two words).

What is dynamic equilibrium?
