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
What is the word that describes the cell membrane as permitting some things in and blocking other things from entering. 

What is semi-permeable

200

The movement of all 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 inside and outside the cell, so water travels in and out of the cell at equal rates.

What is isotonic?

300
A structure within a cell that performs a specific function.
What is an organelle?
300

What organelle makes lipids for the cell membrane?

What is the smooth ER?

300

Diffusion of water- water traveling in and out of the cell 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 and therefore MORE water inside the cell- m water travels outside the cell and so the cell shrinks.

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, and therefore more water on the outside- so water travels into the cell 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

Why is the cell membrane called a phospho-lipid bi-layer?

What is because it is made of phophate and lipids and has two layers.

500

These size molecules move easily through a cell membrane.

What are small?

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... balanced and stable like a good HOME.

What is homeostasis?
