Cell Work

3. the type o fat that composes the cell membrane
5. a thin lipid bilayer that surrounds cells
7. a solution in which the intake and exiting of water into the cell is equal
8. the random motion of gases, particles or molecules across the membrane
9. the direction of movement, or the "force" behind diffusion
11. a type of transport which does not require energy expenditure
12. a type of diffusion which uses proteins to assist in transport across the membrane
15. a solution in which there is more salts or sugars than there is water, causing the cell to lose water and shrivel up
16. a state of balance or comfort all organisms work to maintain
17. another term for cell death

1. an increase or decrease in this will cause the cell membrane to become dysfunctional and no longer fluid
2. facilitated diffusion of substances by means of proteins scattered throughout the cell membrane
4. when water flows into a cell and does not stop, causing the cell to explode
6. the state in which the concentration of substances are equal on both sides of the membrane
10. the movement of water across the membrane due to a difference in the concentration of salts or sugars
13. a type of transport which requires energy expenditure
14. a protein that only allows ions to enter in order to pass through the cell membrane
