Cellular Transport

What type of transport is this? Be specific:

When water moves into a cell.

• facilitated diffusion

• endocytosis

• osmosis

• diffusion

Solutes are at equilibrium in and outside the cell.

• hypertonic

• hypotonic

• isotonic

A test tube of water containing 0.8 mg of salts, holding a cell whose cytoplasm has a concentration of 0.02 mg salts.

• hypertonic

• hypotonic

• isotonic

What are the two main macromolecules in a cell membrane?

• carbohydrates & lipids

• lipids & proteins

• proteins & carbohydrates

• nucleic acids & lipids

In a hypertonic solution, water will move ____ the cell, causing the cell to ________.

• out of; shrink

• out of; swell

• into; shrink

• into; swell

In a hypotonic solution, water will move ____ the cell, causing the cell to ________.

• out of; shrink

• out of; swell

• into; shrink

• into; swell

Diffusion is the movement of particles

• from low to high concentration
• from  high to low concentration
• from equilibrium to areas of high concentration
• all of the above

What characteristic of the cell membrane allows only certain material to pass through?

• selective gating
• selective permeability
• hydrophilia
• selective service

Placing a cell in an isotonic solution causes the cell to

• shrink
• swell
• stay the same

Placing a cell containing 10% salt into a solution containing 7% salt will cause the cell to 

• shrink
• swell
• stay the same
