Ans 206- Osmosis And Diffusion Lab

Front 1

What is ICF and ECF?

Back 1

intracellular fluid- in the cell

extracellular fluid- outside the cell

Water moves btw across the cell membrane

Front 2

___= Passive transport system, where water moves across the cell membrane from LOW to HIGH solute concentration
EX: swimming in a pool/ocean, and your fingers pruning
-curing meat
- frogs dont drink water, they absorb it thru their skin

Back 2

osmosis

Front 3

___= passive transport where substances move from area of HIGH to LOW solute concentrations
EX: perfume spreading throughout the room
-alcohol crossing the BBB
-gases
- dye in water spreading

Back 3

diffusion

Front 4

What is normal physiological saline?
Is it isotonic, hypertonic, hypotonic?

Back 4

.9% NaCl
isotonic- same pressure

Front 5

___= solution has lower concentration of the solute, lower pressure than the cell
-to create, you dilute the water
___- when the cell swells in this solution as water enters the cell, going from area of low solute concentration to higher solute concentration

Back 5

hypotonic

hemolysis

Front 6

___= solution has higher pressure, higher solute concentration in the ECF than the ICF
- to create, you add salt
___= occurs in this solution, causes the cell the shrink as water leaves the ( low to high solute concentration)

Back 6

hypertonic

crenation

Front 7

___= how water moves in and out of the cell

Back 7

aquaporins

Front 8

___= made of lipid bi-layer of polar heads and non-pokar tails, transmembrane proteins, and is selectively permeable to water
- transport is either passive or active

Back 8

cell membrane

Front 9

___= solution has the same osmotic pressure as the cell, .9% NaCl
-Normal physiological saline

Back 9

isotonic

Front 10

___= polymer used in experiment that has a large number of glucose

___= monosaccharide, simple sugar ( source of energy for the cell)

___= indicator of starch (deep blue/dark purple when in the present of starch)

___= permeable to glucose, not starch

Think of experiment

Back 10

starch

glucose

iodine

dialysis tubing

Front 11

___= the constituent of a solution that is dissolved in the solvent

___= the constituent of a solution that dissolves the solute

___= The ratio of the mass or volume of a solute to the mass or volume of the solvent

Back 11

solute

solution

concentration
