Cell Transport and Plasma Membrane

Particle of movement from an area of lower concentration to an area of higher concentration.

• Active transport

• Passive transport

A blood cell is placed into the jar, as seen. Where will the water go?

• Into the cell

• Out of the cell

• Equally in & out - it's isotonic

• The water is a lie

Which of the following is the best example of osmosis? 

• NA/K Pump 

• Water moving though the cell membrane 

• Kidneys 

• Photosynthesis 

The movement of molecules from an area of high concentration to an area of low concentration.

• Osmosis

• Respiration

• Diffusion

• Active Transport

What is diffusion?

• The movement of water across a semipermeable membrane

• The movement of molecules from an area of high concentration to an area of low concentration

• The movement of molecules from an area of low concentration to an area of high concentration

• The movement of ions across a membrane

What happens to a cell placed in a hypotonic solution?

• A. It swells

• B. It shrinks

• C. It remains the same

• D. It bursts

What is the main function of the cell membrane?

• To provide structure to the cell

• To control the movement of substances in and out of the cell

• To produce energy for the cell

• To store genetic information
