It will probably ________________ This diagram represents a animal cell in a _______________ solution. hypertonic It will probably ________________ shrink swell & burst stay the same size shrink

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

endocytosis This type of transport is called _______________ 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

ACTIVE ____________ transport can move molecules AGAINST the concentration gradient. Active Passive When you mix iodine with ____________ you will see a black/purple color change. starch

It will probably ________________ This diagram represents an animal cell in a _______________ solution. hypotonic It will probably ________________ shrink swell & burst stay the same size This process is called _________________ swell & burst cytolysis

Passive ___________ transport does NOT require energy to move molecules.

proton 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 membrane proteins to help molecules move across membranes Facilitated diffusion with carriers, Facilitated diffusion with ion channels, Facilitated diffusion with aquaporins (osmosis) Na+-K+ pump proton pump

selectively permeable A membrane that lets certain molecules pass through and not others is called _______________ Semi permeable OR selectively permeable Image from: http://www.d.umn.edu/~sdowning/Membranes/membraneImages/jpegimages/diffusionmedium.jpg

Exocytosis, endocytosis Name a kind of transport that uses vesicles to move substances across a membrane Exocytosis, endocytosis Name the kind of transport that moves WATER across cell membranes OSMOSIS (Facilitated diffusion with aquaporins)

A freshwater fish has about 1% salt in his body 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 inside the fish’s cells than in the freshwater. (HYPOTONIC) Water will move INTO 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)

plasmolysis carrier protein 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 http://bio.winona.edu/berg/ANIMTNS/facdifan.gif

The energy for active transport comes from this molecule http://www.estrellamountain.edu/faculty/farabee/biobk/BioBooktransp.html The type of transport that moves substances OUT of cells is called ______________ exocytosis The energy for active transport comes from this molecule ATP

isotonic It will probably __________________ This diagram represents an animal cell in a ___________ solution. isotonic It will probably __________________ Undergo cytolysis Undergo plasmolysis stay the same size stay the same size

Tell if the transport is ACTIVE or PASSIVE Facilitated diffusion ___________________ Osmosis ____________________ Na + - K+ pump ____________________ Diffusion ____________________ Endocytosis _______________________ Exocytosis ________________________ Ion channels ________________________ Proton pump _______________________ PASSIVE PASSIVE ACTIVE PASSIVE ACTIVE ACTIVE PASSIVE ACTIVE

The osmotic pressure in this cell will _______________ This diagram represents an plant cell in a _______________ solution. hypotonic The osmotic pressure in this cell will _______________ increase decrease increase

EXOCYTOSIS Match the picture with the kind of transport http://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBooktransp.html EXOCYTOSIS Substance is put in a vesicle and transported up to the cell membrane and released OUTSIDE INSIDE OUTSIDE CELL CELL

ENDOCYTOSIS Match the picture with the kind of transport http://academic.brooklyn.cuny.edu/biology/bio4fv/page/endocytb.htm ENDOCYTOSIS Substance is transported INTO cell inside a vesicle

molecules outside the fish’s cells than in. Ocean water has a greater concentration of dissolved solutes than the organisms that live there so ocea fish live in a _______tonic environment. Will water move into or out of this kind of fish? More solute molecules outside the fish’s cells than in. Water will move leave the fish HYPER

ENDOCYTOSIS Match the picture with the kind of transport http://academic.brooklyn.cuny.edu/biology/bio4fv/page/cell-movement.html ENDOCYTOSIS Substance is transported INTO cell inside a vesicle

HYPERTONIC ISOTONIC HYPOTONIC

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 need energy (passive transport) Pumps move against the gradient (low →high) Carriers/channels move with the gradient (high → low)
