Cell Transport

The movement of particles from a region of high concentration to a region of low concentration is called ____________.

• Osmosis

• Diffusion

• Active Transport

• Secretion

When a potato strip is placed in pure water, after some time it becomes :

• soft

• withered

• swollen

• shorter

The process demonstrated in the diagrams above is responsible for

• Minerals entering root cells

• Carbon dioxide entering leaf cells

• Starch entering Phloem cells

• Water entering root cells

Which statement BEST describes what will be observed after a few hours?

• The level of the water in the beaker will increase

• The sugar particles will dissolve

• The level of the water in the beaker will decrease

• The sugar molecules will diffuse through the potato

Why will a plant die if you water it with a salt water?

• hypotonic solution
• hypertonic solution
• isotonic solution
• silly solution

Two different solutions are separated by a membrane permeable only to water. How will molecules move?

• solutes will move by dissolving
• water will move by active transport
• solutes will move by osmosis
• water will move by osmosis

Your gums are swollen. How will rinsing with warm salt water help the swelling?

• swollen gums will absorb the salt
• salt lowers the temp
• salt goes against the concentration gradient
• water in the gums has diffused out of the cells

Movement of particles from high to low concentration. 

• Passive Transport
• Active Transport

Osmosis is a form of ______________. 

• Passive Transport
• Active Transport

Solutes move with the concentration gradient, therefore no energy is used. 

• Passive Transport
• Active Transport
