Vocabulary List #5

I can describe the 6 processes of passive transport.

Vocabulary List #51. Hypertonic Solution- a solution that has more solute in it than

a cell.2. Hypotonic Solution- a solution that has less solute in it than a

cell.3. Isotonic Solution- a solution that has the same solute

concentration as a cell.4. Passive transportprocess of moving substances into/out of

the cell that requires no energy.5. Mitochondria- organelle that produces energy for the cell.6. Concentration gradient- the difference in concentrations

between two areas.7. Selectively Permeable- term used to describe the cell

membrane only allowing some things to enter/exit the cell.8. Homeostasis – the ability of the cell/body to maintain a

constant environment.

Passive Transport1. Movement of particles into and

out of the cell, with no energy being used

2. Always going from high to low concentration.

3. Always trying to reach equilibrium.


Four Types of Passive TransportDiffusionOsmosisFiltrationFacilitated

Diffusion


Analyze the chart , which term describes what the particles are trying to achieve when the divider is removed? (B.1.f, DOK2)

A. equilibrium B. equality C. equation D. equinox


DiffusionDiffusion- movement

of particles from areas of high to low concentration.

The particles move because of kinetic energy, not energy used by the cell.

DiffusionEquilibrium- when

the number of particles is the same in a given area.

Even at equilibrium the particles will NEVER stop moving.


Calculating SpeedSpeed= Distance (m) Time (s)

In the car we do not measure in m/s, we measure in ___.


Speed GraphCalculate speed of a toy tractor 10 times.

Graph all 10 trials as points on the graph.

Draw a Line of Best Fit.


OsmosisOsmosis- movement of

water into and out of the cell with no energy expenditure.

The cell membrane is selectively permeable to water.

Like particles in diffusion water wants to achieve equilibrium inside and outside the cell.


OsmosisThere are three

different types of solutions that will cause water to move into and out of the cell.

Isotonic solutions -Hyper tonic

solutions -Hypotonic solutions

Osmosis #1Isotonic solutions-the

same amount of solute exists inside and outside the cell.

Water moves INTO / OUT OF the cell at the SAME rate.


Osmosis #2Hypertonic

solutions- have more solutes in solution than inside the cell.

Water moves OUT of the cell to achieve equilibrium.


Osmosis #3Hypotonic solutions-

have less solutes in them than inside the cell.

Water ENTERS the cell to try and achieve equilibrium.


Vocabulary List #61. Hypertonic Solution- a solution that has more solute in it

than a cell.2. Hypotonic Solution- a solution that has less solute in it

than a cell.3. Isotonic Solution- a solution that has the same solute

concentration as a cell.4. Diffusion- movement of particles from high to low

concentration that requires no energy.5. Osmosis- movement of water from an area of high to low

water concentration that requires no energy.6. ATP- form of energy used by the cell.7. Filtration- pressure driven process that uses no energy.8. Facilitated Diffusion – the process of diffusion using a cell

membrane protein.

1. ___ If a cell were placed in pure water, predict the most likely consequence if left untouched for 12 hours? (B.1.e,DOK3)

A. the cell would shrink B. the cell would burst C. the cell would maintain its size

and shape D. the cell would alternate in size:

growing and shrinking


2. ___ A person sets sail across the Atlantic Ocean, but forgets to bring any water; therefore, they are forced to drink salt water. Infer from your knowledge of passive transport what is most likely going to occur in the next few days? (B.1.e,B.1.g, DOK3)

A. death from osmosis; drinking a hypertonic solution

B. death from diffusion; drinking a hypertonic solution

C. death from osmosis; drinking a hypotonic solution

D. death from diffusion; drinking a hypotonic solution

types of osmotic solutions we learned about yesterday?

FiltrationFiltration- pressure

driven system that pushes water and nutrients across cell membranes.

This is how urine is produced

Does not require energy.

Facilitated Diffusion

Facilitated diffusion- within the cell membrane are channel proteins that allow materials to pass into the cell.

Does not require energy.

Three Categories of Active TransportCellular PumpsVesicular TransportCell Ingestion


Vesicular TransportProcess that substances enter/exit the cell.1. Endocytosis- substances are brought into

the cell.2. Exocytosis- substances exit the cell.

passive transport systems?2. Describe what this graph is depicting

(showing).


Active Transport=Needs Energy

Processes that use energy (ATP). Go from regions of lesser to greater

concentrations.


Cellular PumpsCell membrane

proteins that pump substances through the cell membrane.

Endocytosis- 3 Types1. Phagocytosis- process by which cells eat

other cells or large materials.

2. Pinocytosis-process by which cells consume fluid

3. Receptor mediated endocytosis-receptors on the cell membrane attach to needed particles and pull them into the cell.


ExocytosisThe removal of

things from your cell.

Leave through a vesicle that fuses with the cell membrane.
