1.
Separates the cell from its surroundings, made of phospholipid bilayer and proteins
2.
The head of a phospholipid that likes water
3.
The tail of a phospholipid that dislikes water
4.
Cell membrane made of proteins and the phospholipid bilayer
5.
A property of cell membranes that allows some substances to pass through, while others cannot
6.
Movement of substances across a cell membrane without the use of energy by the cell (osmosis, diffusion, facilitated diffusion)
7.
Movement of molecules from an area of higher concentration to an area of lower concentration.
8.
Process of diffusion in which larger molecules pass across the membrane through protein channels
9.
Diffusion of water through a selectively permeable membrane
10.
Solution whose solute concentration is equal to the solute concentration inside a cell; cell stays the same size
11.
Solution with a lower concentration of solutes compared to the cytoplasm inside the cell; cell increases in size
12.
Solution with a higher concentration of solutes compared to the cytoplasm inside the cell; cell decreases in size
13.
Using a transport protein to move substances against their concentration gradient
14.
Moves substances from areas of low concentration to areas of high concentration using energy (protein pumps; endocytosis; exocytosis)
15.
Process by which a cell takes in a substance by surrounding it with its cell membrane; "enters"
16.
A type of endocytosis in which the cell ingests extracellular fluid and its dissolved solutes; "cell drinking"
17.
A type of endocytosis in which a cell engulfs large particles or whole cells; "cell eating"
18.
Process by which a cell releases large amounts of material; "exits"
