Brownian movement
|
random movement due to kinetic energy
|
|
Passive transport (simple diffusion)
|
-High to low concentration
-requires no energy -Due to Brownian movement |
|
Facilitated diffusion
|
-High to low concentration
-requires no energy -Brownian movement & Carrier Molecule |
|
Active Transport
|
-High to low/Low to high concentration
-requires energy -Carrier molecule |
|
Factors effecting membrane permeability
|
-solubility
-poisons -types of molecules -pressure -size of molecules vs. pore(channels -temperature -concentration -PH |
|
if the cell is Isotonic
|
then the water in the cell will stay the same and the cell could reach equilibrium
|
|
crenate
|
to shrink - animal
|
|
if the cell is Hypertonic
|
then the water in the cell will decrease and the cell could crenate or plasmolyze
|
|
if the cell is Hypotonic
|
then the water in the cell will increase and the cell could burst (animal) or be turgid (plant)
|
|
-plasmolyze
-plasmolysis |
-tonoplast of plant shrinks/loses turgor pressure
-keep cell wall's shape |
|
Lysis
|
bursting of an animal cell
|
|
Turgid
|
increasing of turgor pressure (swelling of a tonoplast)
|
|
Tonicity
|
refers to the solute -concentration comparing the outside solution to the inside of a cell
-(Iso/Hyper/Hypo - all have to do with solute solution outside of cell) |
|
Concentration Gradient
|
-the difference in concentration of molecules
-bigger the difference = bigger the gradient |
|
Homeostasis
|
things can be transported in and out of the cell maintaining homeostasis
|
|
Energy
|
Brownian movement - random motion due to kinetic energy
|
|
Unity within Diversity
|
-All transport but some use different ways = energy, help, etc...
-different things are getting transported -all go from high to low, but some do both |
|
Rate of osmosis when sugar concentration increases
|
rate of osmosis goes up as the sugar concentration increases
|
|
Starch + Lugol iodine
|
turns black or purple
|
|
Glucose + Benedicts + heat
|
from blue -> green -> yellow -> orange -> brown
|
|
Protein + Biuret's
|
from royal blue -> purple
|
