solution with lower solute concentration on outside of cell and higher solute concentration on inside of cell. Water will into the cell causing the cell to swell and eventually burst

a solution that has the SAME solute concentration on the outside and inside of the cell. There will be NO NET MOVEMENT of water into or out of the cell. Cell size will stay the SAME.

the movement of molecules LIKE OXYGEN OR HYDROGEN from areas of higher concentration to areas of lower concentration.

molecules LIKE GLUCOSE AND SALT diffuse across the cell membrane with help from membrane PROTEINS, such as channel and carrier proteins.

type of membrane transport that does NOT require energy to move substances across cell membranes. This includes diffusion, osmosis, and facilitated diffusion.

a kind of cellular transport where substances move against a concentration gradient. This type of transport REQUIRES ENERGY from the cell. This includes endocytosis and exocytosis.

process that occurs when a cell moves large materials OUTSIDE of the cell through secretory vesicles. This type of transport is active and requires energy.

a process by which cells absorb or take in external materials by engulfing it (taking in) with the cell membrane. Examples of this is pinocytosis and phagocytosis.

a process by which the cell takes in the fluids along with dissolved small molecules. Pre-fix means to drink.

process by which a phagocyte (a type of white blood cell) surrounds and destroys foreign substances (such as bacteria) and removes dead cells.

the MOVEMENT OF WATER molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules

a type of transport protein, acts like a pore in the membrane that lets water molecules or small ions through quickly

a two-layered arrangement of phosphate and lipid molecules that form a cell membrane.

the cell membranes' ability to differentiate between different types of molecules, only allowing some molecules through while blocking others.

This image is a model of-

Hydrophobic region of the cell membrane?

Hydrophilic portion of cell membrane?

A ______________ is composed of a phosphate and glycerol head and 2 fatty acid chain tails.

Passive Transport is the movement of particles across the membrane from an area of [ ___ ] to an area of [ ___ ]

Passive Transport uses ____ energy

The passage of a substance from an area of high concentration to an area of low concentration

The energy molecule that powers some modes of transport

Water moves into the cell causing the cell to expand:

Small nonpolar molecules (oxygen and carbon dioxide) can pass directly through the cell membrane:

Water moves out of the cell causing it to shrink in size:

Movement of water through the cell membrane is equal:

Type of membrane transport that does NOT require energy:

A state that exists when the concentration of a substance is the same throughout a space:

This molecule powers the sodium-potassium pump.

Energy from ATP changes the carrier protein's _______ to move molecules in and out of the cell.

Which is true of the sodium-potassium pump?

How many sodium ions are moved by the sodium potassium pump?

How many potassium ions are moved by the sodium potassium pump?

The active transport of ions across the membrane causes an _______________ gradient to build up across the cell membrane.

This is the electrical potential energy that is caused by a separation of opposite charges.

The voltage across a membrane is called___________________.

The cell shrunk in size, which means it was placed in a ____ solution.

The cell expanded in size to the point of lysing (bursting), which means it was placed in a ____ solution.

Some cells move large particles out of the cell through the process of:

In passive transport, substances move across the cell membrane ________ the concentration gradient
