Cell Theory
Passive Transport
Active Transport
100
This controls the movement of materials into and out of the cell.
cell membrane
100

These organic compounds stores genetic information in the cell (HINT: DNA)

Nucleic Acids
100
According to "The Cell Theory," all living things are composed of _____________.
Cells
100
In passive transport, molecules move from areas of _________ concentration to areas of _________ concentration.
High to Low
100

In active transport, molecules move from areas of _________ concentration to areas of _________ concentration.

Low to High
200
This directs the cell's activities and is known as the "control center" of the cell.
The nucleus
200
These are specialized proteins that speed up chemical reactions (HINT: digestion)
Enzymes
200

According to "The Cell Theory," cells are the basic units of __________ and ____________ in living things.

structure & function
200
The process in which water molecules move from a high to a low concentration, across the cell membrane.
Osmosis
200
Active transport is different from passive transport because it requires the use of cellular __________!
Energy
300
These convert food into energy the cell can use.
Mitochondria
300

These organic compounds gets stored as energy for later use (HINT: fat)

Lipids
300

According to "The Cell Theory," all cells are ___________ from other cells.

Produced or made
300
The process of oxygen molecules moving from a high to a low concentration. 
Diffusion
300
The process in which the cell membrane changes shape to engulf large particles. 
Endocytosis
400
This surrounds a plant cell and helps support it.
The cell wall
400

These organic compounds provide ENERGY to cells.  They are also important components of cell walls and  cell membranes (HINT: Sugars & Starches)

Carbohydrates
400
A _____________ is an instrument that needs to be used in order to see cells because they are so small!
Microscope
400
The process in which molecules move from a high to a low concentration, through protein channels. 
Facilitated diffusion
400

The process in which the cell membrane changes shape to expel large particles. 

Exocytosis
500
These two organelles modify proteins and moves them around the cell. 
Endoplasmic Reticulum & Golgi Apparatus
500
What is the difference between an element and a compound?
Compounds are two or more chemically bonded elements, and elements are substances that cannot be broken down.
500
What are 3 differences between an animal cell and a plant cell?


1. Large central vacuole vs. small vacuoles

2. Cell Wall (plant cells)

3. Chloroplasts (plant cells)

500
Explain why the gummy bear grew in the fresh water and shrank in the salt water. 
The gummy bear grew because water molecules diffused into the bear.  The gummy bear shrank in salt water because water molecules inside it diffused out of the bear into the salty water. 
500
Glucose molecules move from areas of low to high concentration through __________ _________.
Transport Proteins
