Osmosis Flashcards
Diffusion of water across a differentially selectively permeable membrane due to a concentration gradient.
Osmosis
Net movement of water molecules from higher water potential (__ concentration) to lower water potential (__ concentration).
Lower solute
Higher solute
Osmosis
Molecules that pass a semipermeable membrane
Water and Salt
Solute concentration same as the cell
Isotonic
Solute concentration lower than the cell
Hypotonic
Solute concentration higher than the cell
Hypertonic
Isotonic liquid movement
No net movement
Hypotonic liquid movement
Inward net movement
Hypertonic liquid movement
Outward net movement
RBC swells and potentially bursts and turn as ghost cells.
Biconcave cell shape to spherical cell shape.
Hypotonic
RBC retains its shape and size because the solute concentration inside the cell is equal to the surrounding solution.
Isotonic
RBC shrinks and loses its volume because the water is drawn out of the cell.
Shape becomes smaller and develops a ___ appearance.
Hypertonic
Wrinkly
Isotonic NaCl solution
0.9 NaCl
Hypotonic NaCl solution
0.5 NaCl
Hypertonic NaCl solution
1.5 NaCl
The rupture or breakdown of red blood cells, resulting in the release of __ into the surrounding liquid.
Hemolysis
Hemoglobin
The shrinkage or wrinkling of cells, often seen in kidney cells, due to dehydration, loss of electrolytes, or changes in osmotic pressure.
Crenation
Swollen and hemolyzed RBCs
Ghost cells
Eukaryotic, hypotonic, freshwater protists
Paramecium sp.
Ables the paramecium sp. to survive hypotonic environments.
Contractile vacuole
