When you sit in the bathtub, your fingers get wrinkly because of the water entering your skin cells. The bathtub water is a ____________ solution compared to your skin cells
hypotonic
Hypotonic isotonic hypertonic
This type of transport is called
_______________endocytosis
http://academic.brooklyn.cuny.edu/biology/bio4fv/page/cell-movement.html
Diffusion continues
until the concentration of molecules is equal throughout the space.
This is called ___________________equilibrium
____________ transport can move molecules AGAINST the concentration gradient.
Active Passive
ACTIVE
starchWhen you mix iodine with ____________you will see a black/purple color change.
This diagram represents an animal cell in a _______________ solution.hypotonic

shrink swell & burst stay the same size
This process is called _________________
swell & burst
cytolysis
___________ transport does NOT require energy to move molecules.
Passive
Give some examples
of membrane proteins
that help move
molecules across
cell membranes
H+ ions move across cell membranes using __________ pumps
Carriers, ion channels, aquaporins, pumps
proton

Name a kind of transport that uses vesicles to move substances acrossa membrane
Exocytosis, endocytosis
Name the kind of transport thatmoves WATER across cell membranes
OSMOSIS (Facilitated diffusion with aquaporins)
A freshwater fish has about 1% salt in his body. Freshwater is close to 0% salt.
Will water move into or out of this kind of fish?
More solute molecules insidethe fish’s cells than in the freshwater.(HYPOTONIC)Water will moveINTO the fish
The white circles stand for oxygen molecules.
Use what you know about diffusion of molecules to predict which way the oxygen will move.
From the lungs into the blood(Move from a High concentration to low concentration)
The shrinking away of the cell membrane from the cell wall in a plant cell when placed in a HYPERTONIC environment
plasmolysis
An INTEGRAL MEMBRANE PROTEIN that moves molecules PASSIVELY across cell membranes by attaching, CHANGING SHAPE, and flipping to the other side like a revolving door
carrier protein

The type of transport that moves substances OUT of cells is called
______________exocytosis
The energy for active transportcomes from this molecule

HYPERTONIC HYPOTONICISOTONIC
Healthy cells work to “maintain stable internal conditions” also called ____________. If this doesn’t happen, cells can be damaged.
(That is what happens when cells shrink or swell in hypotonic or hypertonic solutions.)
homeostasis
HOW are pumps different from facilitated diffusion carriers and channels?
Pumps require energy (active transport)and carriers and channels don’t needenergy (passive transport)
Pumps move against the gradient (low →high)Carriers/channels move with the gradient (high → low)
