Cell Processes

Front 1

eukaryote

Back 1

any of the single-celled or multicellular organisms whose cell contains a distinct, membrane-bound nucleus.

Front 2

prokaryote

Back 2

any of the group of organisms primarily characterized by the lack of true nucleus and other membrane-bound cell compartments.

Front 3

selectively permeable

Back 3

a feature and a function of the plasma membrane that is essential to maintain homeostasis by regulating the passage of some substances while preventing others from entering the cell.

Front 4

diffusion

Back 4

a type of passive transport (spontaneous, therefore, it is a net movement of molecules in and out of the cell across the membrane along a concentration gradient (higher concentration to lower concentration).

Front 5

facilitated diffusion

Back 5

when molecules move (diffuse) via special transport proteins found within the cell membrane.

Front 6

osmosis

Back 6

tendency of water to flow from a hypotonic solution (low concentration of dissolved substances) to hypertonic solution (high concentration of dissolved substances) across a semipermeable membrane.

Front 7

isotonic

Back 7

having equal tension or pressure.

Front 8

hypertonic

Back 8

higher concentration

Front 9

hypotonic

Back 9

lower concentration.
