Question

You are a medical scientist who has been doing research on dialysis patients to better understand the

effect of different solutions on blood cells. You put a patient's blood cell in three mineral solutions: a
hypertonic, hypotonic, and isotonic solution. Make a prediction for how a blood cell will react in
each type of solution. Make sure your answer includes how different types of solute concentrations
affect water movement through a semi-permeable membrane.

Answer 1

Hypertonic: cell with shrivel

Hypotonic: cell will lyse (expand)

Isotonic: cell with not change

Step-by-step explanation:

Hypertonic has a higher concentration outside the cell so there will be a net flow of water out of the cell

Hypotonic has a lower concentration outside the cell so there will be a net flow of water into the cell

Isotonic is when the concentration is the same so there will be no net flow of water

Answer 2

An hypertonic solution has a higher concentration than the inside of the cell's cytoplasm, a hypotonic solution has a lower concentration that the cell's cytoplasm an isotonic solution has the same concentration as the cell's cytoplasm. When placed in a hypertonic solution the cell will lose water through osmosis and will shrink. When placed in a hypotonic solution the cell will absorb water through osmosis and it will increase in size untill it bursts. This proces is called cytosis. When placed in an isotonic solution the cell will keep it's initial size.
