1. The change in the appearance off the cell resulted from more…
1. water flowing into the cell than flowing out of the cell
2. water flowing out of the cell than flowing into the cell
3. salt flowing into the cell than flowing out of the cell
4. salt flowing out of the cell than flowing into the cell

2. How would several of these phospholipids arrange themselves if placed in water?
A Phospholipid

7. Can you explain this? 5% Starch Solution
25% Starch Solution (the purple represents starch)

8. Hypertonic solution

9. Hypotonic solution

10. Isotonic-
THE CONCENTRATION OF DISSOLVED PARTICLES IS THE SAME INSIDE AND OUTSIDE THE CELL
Hypertonic
THE CONCENTRATION OF DISSOLVED PARTICLES IS HIGHER OUTSIDE THE CELL THAN INSIDE THE CELL
Hypotonic
THE CONCENTRATION OF DISSOLVED PARTICLES IS LOWER OUTSIDE THE CELL THAN INSIDE THE CELL

11. Is the solution outside the cell isotonic, hypotonic, or hypertonic?

12. Is the solution outside the cell isotonic, hypotonic, or hypertonic?

13. Is the solution outside the cell isotonic, hypotonic, or hypertonic?

14. Is the solution outside the cell isotonic, hypotonic, or hypertonic?
