Cell Structure and Function

2. A lipid bilayer that with contains proteins which is constantly in motion.
3. cells are the basic unit of life, all cells come from other cells, living organisms contain one or more cells.
4. A property that allows the plasma membrane to control movement of particles in and out of the cell.
9. This process moves things across the plasma membrane against the concentration gradiennt and requires energy.
10. Taking into the cell.
12. This causes no net movement of water as the solution inside and outside of the cell are the same.
13. Diffusion of water across a selectively permeable membrane.
14. The basic unit of structure and function of all living things.
16. A membrane that contains molecules with polar heads facing out and nonpolar tails facing in.
18. a membrane bound organelle that controls the functions of the cell and protects the genetic information.
19. This random process constantly moves particles evenly.
20. The internal part(s) of a cell that carries out specific functions.

1. controls what enters and leaves the cell through a selectively permeable membrane.
2. This process moves ions and particles through the plasma membrane through transport proteins.
5. Moving out of the cell.
6. Protein Moves substances in and out of the plasma membrane.
7. Cell does not contain a nucleus or membrane bound organelles.
8. This causes water to move out of the cell through osmosis due to high concentrations of solute outside of the cell.
11. Cell has organelles, a membrane, and a nucleus
15. This causes water to move in the cell through osmosis due to low concentrations of solute outside of the cell.
17. This process moves particles across the plasma membrane from an area of high concentration to low.
