Science

1. Transport energy-requiring movement of molecules across a membrane from a region of lower concentration to a region of higher concentration
6. uptake of a solid particle into a cell by engulfing the particle
8. uptake of liquids or large molecules into a cell by inward folding of
9. Permeability condition or quality of allowing some, but not all, materials to cross a barrier or membrane
11. movement of dissolved molecules in a fluid or gas from a region of higher concentration to a region of lower concentration
14. release of substances out a cell by the fusion of a vesicle with the membrane
15. protein that detects a single molecule and preforms an action in response
16. Mosaic Model model that describes the arrangement and movement of the molecules that make up a cell membrane

2. Gradient difference in the concentration of a substance from one location to another
3. Diffusion diffusion of molecules assisted by protein channels that pierce a cell membrane
4. molecule that forms a double layer cell membrane; consists of a glycerol, a phosphate group, and two fatty acids
5. solution that has a lower concentration of dissolved particles compared with another solution
7. solution that has a higher concentration of dissolved particles compared with another solution
10. diffusion of water molecules across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration
12. solution that has an equal concentration of dissolved particles compared with another solution
13. cell membrane
