Cells

1. A concentration that has low concentration of solutes relative to an adjacent solution.
2. transport of material sacross the cell's plasma membrane that involves no expemditure of energy.
4. the means by which relatively large volumes of materials are moved from the inside of the cell to the outside.
6. the movement of large materials into a cell by means of wrapping extentions of the plasma membrane around the materials and fusing the extentions together
8. The movement of relatively large materials into a cell ny means of the creation of transportr cesicles that are produced through an incagination of the plasma membrane.
10. A gradient within a given medium defined by the difference between the highest and the lowest concentration to lower, thus diffusing.

1. a solution that has a high concentration of solutes relative to an adjacent solution.
3. a solution that has the same concentration of solutes as an adjacent solution.
5. a membrane forming the outer boundry of many cells, composed of a phosphloid bilayer intersped with proteins and cholesterol molecules and coated on its exterior face with short carn. chains associated with protein lipids.
7. the net movement of water across a semipermeable membrane from an area of higher solute concentration.
9. a passage of materials through the cell's plasma membrane that is aided by a transport protein.
11. a protein that forms a hydrophilic channel through the hydrophobic interior of the cells plasma membrane.
12. transport of materials across the plasma membrane in which energy is expended.
13. the process by which cells bring relatively large materials into themselves through the use or transport vesicles.
