Movement of ANY PARTICLES or MOLECULES from an area of HIGH concentration TO an area of LOW concentration

DIFFUSION of WATER across a selectively permeable membrane - AQUAPORIN PROTEIN REQUIRED, but NO ENERGY!

A membrane that allows certain materials to pass through, but not others

The condition that exists in system when there is a relatively equal distribution of a particular molecule

The "Gateway" - Regulates and controls what enters or leaves the cell - Composed of a Phospholipid Bilayer

Movement of molecules or ion into or out of the cell AGAINST its concentration gradient (from low to high) and requires an INPUT of ENERGY

Movement of substances INTO the cell by creating a new VACUOLE/VESICLE at the cell membrane. REQUIRES ENERGY.

Movement of substances OUT of a cell by merging a VACUOLE/VESICLE with the cell membrane REQUIRES ENERGY.

HIGHER solute concentration outside of cell= "SUCKS" water out of the cell = cell has negative change in mass - SHRINKS

"CELL EATING" a type of ENDOCYTOSIS in which large particulate substances or small organisms are TAKEN UP by a cell. It's carried out by some protists and by certain immune cells of animals.

A phenomenon in WALLED CELLS in which the CYTOPLASM SHRIVELS and the PLASMA MEMBRANE PULLS AWAY from the CELL WALL; occurs when the cell loses water

"CELL DRINKING"; a type of ENDOCYTOSIS in which the cell TAKES FLUID and dissolved solutes INTO small membranous VESICLES

An EMBEDDED PROTEIN that HELPS a certain type of substance to CROSS the MEMBRANE

The TAIL of a phospholipid molecule that is REPELLED by WATER

The HEAD of a phospholipid molecule that is ATTRACTED to WATER

The molecule that provides ENERGY for cellular processes by breaking the BOND BETWEEN the 2nd & 3rd Phosphates

LOWER solute concentration outside of cell= "BLOWS" water INTO the cell = cell has positive change in mass/SWELLS

A SOLUTION in which the concentration of solutes is essentially EQUAL to that of the cell which resides in the solution - No Net mass gain of the cell - SAME

A substance that is DISSOLVED in a solution.

In a solution, the substance in which the solute dissolves.

The PRESSURE that is exerted on the inside the PLANT CELL WALLS and that is caused by the movement of water into the cell - HYPOTONIC condition
