100

The structure that surrounds each cell.

What is the cell membrane?

100
Chromosomes line up in the middle of the cell.

100
The long tube leading from the throat to the bronchi.
What is the trachea?
100
The component of blood responsible for fighting and destroying disease causing bacteria and viruses.
What are white blood cells?
100
The structure begins the process of mechanical and chemical digestion.
What is the mouth?
200
The control centre of the cell.
What is the nucleus?
200
The division of the cytoplasm happens during this stage.
What is cytokinesis?
200
These small grape-like structures are surrounded in capillaries and are involved in gas exchange.
What is the alveoli?
200
The three components of the circulatory system.
What is the heart, blood, and blood vessels?
200
The muscular tube that links the mouth and stomach.
What is the esophagus?
300

The organelle that is only found in plants. 

What are chloroplasts?

300
Cells spend most of their life cycle in this phase.
What is interphase?
300
These hair like structures work to sweep foreign materials out of the airways.
What are cilia?
300
Large blood vessels that carry blood toward the heart.
What are veins?
300
Absorption of nutrients occurs here.
What is the small intestine?
400
This specialized cell contracts to allow movement.
What are muscle cells?
400
Chromosomes are pulled to opposite sides of the cell.
What is anaphase?
400

The main function of the respiratory system.

What is gas exchange (oxygen in and carbon dioxide out)?

400
Two systems that work together to deliver oxygen to body cells.
What is the circulatory and respiratory system?
400
Water absorption mostly occurs in this part of the digestive system.
What is the large intestine?
500

This tissue types makes up the skin and lining of the digestive system. 

What is the epithelial tissue?

500

The chromosomes get replicated (copied) during this phase. 

What is interphase?

500

The process of oxygen moving from high to low concentration.

What is the diffusion?

500

The tiny blood vessels responsible for diffusion between the blood and body tissues.

What are the capillaries?
