Cell Transport Mechanisms for Grade 10

Front

*Front:* Active Transport

Back

of molecules against concentration gradient, requires energy

Front

*Front:* Passive Transport

Back

of molecules down concentration gradient, no energy required

Front

*Front:* Osmosis

Back

of water across a semipermeable membrane

Front

*Front:* Hypertonic Solution

Back

solute concentration outside the cell, causes cell to shrink

Front

*Front:* Isotonic Solution

Back

solute concentration inside and outside the cell, no net water movement

Front

*Front:* Hypotonic Solution

Back

solute concentration outside the cell, causes cell to swell

Front

*Front:* Energy Source for Active Transport

Back

(Adenosine Triphosphate)
