The structure of the cell membrane consists of two layers of:

• proteins
• carbohydrates
• lipids
• nucleic acids

Material moves in and out of the cell through channels made of:

• carbohydrates
• proteins
• lipids
• nucleic acids

The movement of glucose molecules from a high concentration to a low concentration is called: 

• active transport
• diffusion
• osmosis
• inactive diffusion

Skin cells provide protection.  Red blood cells carry oxygen to cells.  White blood cells attack bacteria.  These are all examples of cell:

• work study programs
• interships
• speciation
• specialization

If a wet mount of an Elodea leaf is placed under the microscope and salt water is added to the slide, the cell membrane in the plant cell will:

• expand and push on the outer cell wall
• remain in the same place as when the slide was made
• shrink into the center of the cell
• burst open under the cell wall

The correct order from smallest to largest is:

• chromosome, tissue, organ system, organism, organ
• cell, tissue, organ, organ system, organism
• cell, organ, tissue, organism, organ system
• organ, organ system, organism, cell, tissue

The organelle responsible for the production of energy is the:

• mitochondrion
• nucleus
• ribosome
• chloroplast

A cell containing 5% salt is placed in pure water.  What will happen to the cell?

• Nothing
• water will diffuse into the cell and it may burst
• water will leave the cell and it will shrink
• the salt will diffuse out of the cell and it will shrink
