Cell Transport It’s all about homeostasis  maintaining balance or a constant environment

Cell transport Practice Problems KEY THINGS TO REMEMBER: Water moves from a high to low concentration (osmosis). The plasma membrane is semi-permeable. Water follows salt!

Cell transport examples 1.Given the following internal and external conditions, what would happen to the following cell? 20% H20 80% H20 The cell will shrink!

Cell transport examples 2.Given the following internal and external conditions, what would happen to the following cell? .5% NaCl 5% NaCl The cell will grow (water follows the salt inside of the cell)!

Cell transport examples Given the following internal and external conditions, what would happen to the following cell? 50% H20 50% H20 The cell will stay the same!

Cell transport examples Given the following internal and external conditions, what would happen to the following cell? 70% H20 30% H20 The cell will grow!

Cell transport examples Given the following internal and external conditions, what would happen to the following cell? 1% NaCl .1% NaCl The cell will shrink (water follows the salt outside of the cell)!
