Question

match the words to their definitions.
A. active transport B. endocytosis C. exocytosis D. facilitated diffusion E. hydrophilic F. hydrophobic G. osmosis H. passive transport I. phospholipid bilayer

1. substances diffuse across the plasma membrane with assistance from membrane proteins.
2. cell moves large materials from inside the cell to the outside of the cell using vesicles.
3. when substances cross the plasma membrane, by moving against the concentration gradient, with the aid of specialized proteins and energy from ATP.
4. capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell.
5. does not interact with water.
6. easily interacts with water.
7. a thin semi permeable polar membrane, made of two layers of lipid molecules, that makes up the plasma membrane of a cell.
8. the transport of substances across a plasma membrane in which they move down the concentration gradient without help.
9. the passive transport of water across a plasma membrane. this can be aided by an aquipore to increase the rate of diffusion
